* nuttx/lcd/hd4478ou.h and configs/pcblogic-pic32mx/src/up_lcd1602:
Start of support of LCD1602 alphanumeric LCD. I need a few
more parts before I can finish integrating this one.
* arch/arm/src/*/chip.h and arch/arm/include/*/chip.h: Move all
priority ranges from the src to the include chip.h header file.
* arch/arm/include/armv7-m/irq.h: Add inline functions to enable
and disable interrupts via the BASEPRI register.
* arch/arm/Kconfig: Add new option CONFIG_ARM7VM_USEBASEI
* arch/arm/src/*/*_irq.c: Set the priority of the SVCALL exception
to the highest possible value.
* arch/armv7-m/up_hardfault.c: Fail if a hardfault occurs
while CONFIG_ARM7VM_USEBASEPRI=y.
* arch/arm/src/stm32/stm32_serial.c: Add support for USART
* sched/: Implement support for retaining child task status after
the child task exists. This is behavior required by POSIX.
But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and
CONFIG_SCHED_CHILD_STATUS
* Add support for keyboard encode to the keypad test (from
Denis Carikli).
* configs/olimex-lpc1766stk/nettest: Configuration converted to
use the kconfig-frontends tools.

* net/net_poll.c: Split net_poll() to create psock_poll() too.
* net/net_poll.c: Fix poll/select issure reported by Qiang:
poll_interrupt() must call net_lostconnection() when a
loss of connection is reported. Otherwise, the system will
not know that the connection has been lost.
* sched/group_create.c, group_join.c, and group_leave.c: Add
support for task groups.
* sched/group_signal.c and task_exithook.c: Send signal to all
members for the parent task group.
* include/nuttx/sched.h and sched/env_*.c: Move environment
variables into task group structure.
* sched/: Lots of file changed. Don't keep the parent task's
task ID in the child task's TCB. Instead, keep the parent
task group IN the child task's task group.
* fs/, sched/, include/nuttx/sched.h, and include/nutts/fs/fs.h:
Move file data from the TCB to the task group structure.
* libc/stdio/, sched/, include/nuttx/lib.h, and include/nutts/fs/fs.h:
Move stream data from the TCB to the task group structure.
* net/, sched/, and include/nuttx/net/net.h: Move socket data
from the TCB to the task group structure.

* sched/task_starthook.c, sched/task_start.c, and include/nuttx/sched.h:
Add a task start hook that will be called before the task main
is started. This can be used to schedule C++ constructors to run
automatically in the context of the new task.
* binfmt/binfmt_execmodule: Execute constructors as a start hook.
* sched/os_start.c: Fix ordering of group initialization.
* configs/stm32f4discovery/usbnsh: Add an NSH STM32F4Discovery

all STM32 user LED code. The wrong definitions were being used
patacongo

to set LEDs on or off.
* arch/*/common/up_internal.h and arch/*/common/up_initialize.c:
Serial was driver was not being built if there is no console
device. Obviously, the serial driver may be needed even in
this case.
* arch/arm/src/stm32/stm32_serial.c: If there is a serial console,
it would be ttyS0 and the others would be ttyS1-5. If there
is not serial console, was labeling them ttyS1-6; now labels them
ttyS0-5.
* fs/fs_syslog.c: Can't handle SYSLOG output to character device from
the IDLE task (because it can't block). syslog_putc now returns EOF
on failure and sets errno. Fixed some errors in error handling.
* libc/stdio/lib_syslogstream.c: Checking of return value from
syslog_putc was bogus. Switching to EOF for all errors solves
this.
* arch/arm/src/lm/chip/lm4f_memorymap.h: More LM4F changes from
Jose Pablo Carballo.
* drivers/serial/serial.c, include/nuttx/serial/serial.h,
drivers/usbdev/cdcacm.c, and drivers/pl2303.c: Add support for
removable serial devices (like USB serial). This support is enabled
* arch/*/src/*/Toolchain.defs: Change assignment so that we can
override CROSSDEV with a make command line argument.
* include/assert.h: Mark assertion functions as non-returning.
* arch/*/src/*/up_assert.h: Mark _up_assert() as non-returning.
* drivers/mtd/at25.c: When the AT25 device was not available the
initialization did not fail like it should. From Petteri Aimonen.
* fs/fat/fs_configfat.c: Fix some errors in FAT formatting logic
for large devices and for FAT32. From Petteri Aimonen.
* fs/fat/fs_fat32util.c: Fix an initialization error found by
Petteri Aimonen. freecount and next freecount initialization were
reversed.
* drivers/mmcsd/mmcsd_spi.c: Some SD cards will appear busy until
switched to SPI mode for first time. Having a pull-up resistor on
MISO may avoid this problem, but this patch makes it work also
without pull-up. From Petteri Aimonen.

* drivers/serial/serial.c: Correct some race conditions when checking
for disconnection of a removable serial device.
* sched/task_posixspawn.c, task_spawn.c, task_spawnparms.c and
spawn_internal.h: Create new interface task_spawn() that is
like posix_spawn(), but uses entry point addresses like
task_create().
* Corrected all argv[] arguments. Should be char * const *, not
const char **.
* sched/pthread* and include/nuttx/sched: Move pthread join data
and pthread key calculation data into the "task group" structure.
* sched/atexit.c, on_exit.c, task_exithook.c and include/nuttx/sched.h:
Move atexit and on_exit data structures to task group. These
callbacks are only issued now when the final member of the task
group exits.
* sched/waitpid.c, task_exithook.c and include/nuttx/sched.h:
Move waitpid data data structures to task group. Callers of
of waitpid() are now only awakened whent he final thread of the
task group exits.
* sched/mq_descreate.c, mq_open.c, mq_remove.c, group_leave.c, and
include/nuttx/sched.h: Move list of opened message queues to
the task group structures. Now all message queues opened by
members of the group are closed when the last member of the group
exits.
* includes/nuttx/sched.h and Lots of files: Change name of _TCB to
struct tcb_s so that (1) it is consitent with other NuttX naming and
so that (2) the naming can handle some upcoming changes.
* includes/nuttx/sched.h and sched/: There are three TCB structures:
struct tcb_s is a generic common version, struct task_tcb_s is a
version for tasks and kernel threads and pthread_tcb_s is a version
for pthreads. By dividing the TCB structure into these variants,
pthreads do not have to be burdened by task-specific data structures
(and vice versa).

* sched/task_exithook.c adn group_create.c: Fix an error, the
task within the task group may exit early leaving a pthread to
exit the task group last. In this case, we need to remember the
the PID of the main task in the task group and use that PID for
signalling SIGCHILD to the parent task group.
* included/nuttx/sched.h and sched/sig*.c: Numerous changes to the
signal deliver logic so that the delivery of signals to threads
within a task group will be compliant with delivery of signals
to threads within a POSIX process.
* sched/mq_recover.c and task_exithook.c: Add logic to handle the
case where a task is deleted (or pthread canceled) while it is
waiting on a message queue. task_delete() and pthread_cancel()
are dangerous interfaces. This is only one feeble recover measure
of *many* that would be needed to do this safely.
* sched/group_killchildren.c, task_recover.c, group_foreachchild.c,
sched/restart.c, sched/task_delete.c, and others: Beef up logic
to better support task deletion and pthread cancellation. Needed
to pass need OS test case for task_restart().
* sched/include/sched.h and all timed functions in sched/: Move
timer from local variables to TCB. This is needed so that if a
task is canceled or restarted while it is waiting for a timed
event, we can gracefully recover. We can't let the timer expire
after the task has been deleted.
* arch/arm/include/stm32 and arch/arm/src/stm32: Add support for
the STM32 F3 family (still missing some things).
* configs/stm32f3discovery: This will (eventually) be support for
the STM32F3Discovery board.
* STM32 F3 and STM32F3Discovery port is complete a ready for test.

* drivers/input/max11802.c: MAX11802: Fix a timing bug that
corrupted coordinates. From Petteri Aimonen.
* drivers/mmcsd/mmcsd_spi.c: Use SPI locking so that MMC/SD can
exist on the same bus as other SPI devices. From Petteri
Aimonen.
* graphics/nxfonts/nxfonts_sans17x22.h: Small mod to hyphen in
sans17x22 font. The hyphen did not have any space on its sides.
This caused it to run together with other characters so that for
example "+-" would look weird. From Petteri Aimonen.
* mm/mm_mallinfo.c: Take MM semaphore in mm_mallinfo. From Petteri
Aimonen.
* configs/stm32f3discovery/nsh/defconfig: Disable SPI. It is not
used.
* drivers/mtd/sst39vf: Add a driver for the SST29VF NOR FLASH parts.
* sched/os_start.c: Add an additional call-out to support board-
specific driver initialization during the start phase: If
CONFIG_BOARD_INITIALIZE is defined, then an additioinal
initialization function called board_initialize() will be called
just after up_initialize() is called and just before the initial
application is started.
* arch/arm/src/stm32/stm32_otgfsdev.c, drivers/usbdev/usbdev_trprintf.c,
and include/nuttx/usb/usbdev_trace.h: Add logic to support decoding
of device-specific trace events to make the trace ouput more readable.
From Petteri Aimonen.
* arch/arm/src/stm32/stm32_otgfsdev.c: Need to manually set CNAK in
the case where we are waiting for a SETUP command with DATA. Otherwise,
the core may NAK further transactions. From Petteri Aimonen.
* arch/arm/src/stm32/stm32_otgfsdev.c: Add logic to prevent premature
to IDLE state. This change (plus the previous) was necessary to get
the CDC/ACM driver working the certain STM32 F4 hardware (but not others).
These changes appear to prevent certain race conditions that may or may
not cause USB problems. From Petteri Aimonen.
* arch/arm/include/armv6-m and arch/arm/src/armv6-m: First cut at support

USB descriptor but a truncated, 8-byte name in the SCSI field.
From Petteri Aimonen.
* arch/arm/src/stm32/stm32_spi.c: Need to clear error flags to prevent
corruption of subsequent transfers. Also, bit count should not be
changed while the SPI peripheral is enabled. From Petteri Aimonen.
* drivers/mmcsd/mmcsd_spi.c: When bus is shared, the speed has to be
set every time. Also SD cards require a few dummy clocks to react
into CS release. From Petteri Aimonen.
* configs/lm4f120-launchpad: In initial configuration for testing
the LM4F120 LaunchPad port. This is to support testing only and
is not yet a functional board port (as of 2013-03-01).
* arch/arm/include/lm/lm4f_irq.h and arch/arm/src/lm/chip/lm4f_vector.h:
Add interrupt vector/IRQ number definitions for the LM4F120.
* arch/arm/src/stm32f20xxx_dma.c and stm32f40xxx_dma.c: Fix a typo

Yan T.
* Several build fixes from Mike Smith were incorporated. These were
mostly compilation errors introduced into the system because of the
large number of recent changes with broad scope (2013-03-04).
* configs/zkit-arm-17969/src/up_can.c: Add CAN support to the
Zilogics Technologies ZKIT-ARM-1769 board (From Rashid Fatah, (2013-03-04)).

* libc/wqueue: Work queue logic moved from sched/ to libc/wqueue. It
is not really core OS functionality and this move helps prepare for
user-space work queues. (2013-03-05)

* arch/arm: Correct some bad syscall dispatching logic. This change
cannot be fully tested until there is a fielded NuttX kernel build.
(2013-03-06).
* net/net_poll.c: Correct logic that checks if the socket is
disconnected when the poll is setup. That is bad logic: Listen
sockets, for example, are not connected. In that case, the purpose of
the poll is to wait for connection events. As a result of this,
poll/select would return immediately with POLLHUP with it was used to
detect connection events. This fix for now was to check instead if
the socket is closed (meaning that it was connected at one time but
was closed by the remote peer). That excludes the listen socket which
was never connected. This does introduce a new problem, however. If
the socket was not closed, but lost the connection through an abnormal
event, then poll/select will hang. That needs to be revisited.

* fs/fs_select.c: Was not checking if the timeout parameter was NULL
but would, instead, setup a bogus timeout based on whatever it found at
address zero. Also, improved some of the memory allocation logic so
that it will not use so much memory. (2013-03-07)
* net/net_poll.c: Handle the missing case. Now tests for not connected
AND not listening. I think that now covers all of the cases including
the missing case noted above. (2013-03-07)
* mm/: Move all memory manager globals into a structure. A reference
to this structure is now passed internally between mm APIs. This
change will (eventually) support multiple heaps and heap allocators.

to do with them (which is probably to just delete them). (2013-03-08).
patacongo

* mm/mm_test.c and Makefile.test: Deleted the memory test. This was
a good test and helped me a lot when I wrote the memory manager, but
now it is in the way and paralyzing other efforts. So the memory unit
test was deleted. (2013-03-08)

* configs/sam3u-ek/kernel/up_userspace.c: This is the header for
the SAM3U-EK's user space. (2013-03-10)

(2013-03-12).
* arch/arm, configs/sam3u-ek, configs/open1788: Fix memory map for
kernel mode build; Some regions were overlapping. (2013-03-13).
* arch/: Rename g_heapbase to g_idle_topstack. This is the same value
however: The top of the IDLE stack is the same as the base of the
heap in the flat build. But not in the kernel build: The base of
the heap is elsewhere so the naming was wrong. (2013-03-13).
* libc/stdlib/lib_itoa.c: Implementation of itoa() contributed by
6.27 2013-04-28 Gregory Nutt <gnutt@nuttx.org>
* arch/arm/src/armv7-m/up_mpu.c: Correct MPU sub-region settings for

* configs/lm4f120-launchpad/tools: Add scripts and instructions to
simplify use of OpenOCD with ICDI (from JP Carballo, 2013-03-15).
* tools/mkconfig.c: Logic that attempts to suppress buffered I/O
within the kernel is wrong. sizeof(struct file_struct) must be
the same in both kernel- and user-spaces (2013-03-16).
* arch/arm/src/common/up_pthread_start.c, libc/pthread/pthread_startup.c,
and related files: Implement switch to user-space and user-space
pthread start-up function (2013-03-16).
* arch/arm/src/common/up_signal_handler.c, libc/pthread/pthread_startup.c,

* arch/arm/src/armv[6|7]-m/up_schedulesigaction.c: Need make sure we are
in kernel mode before switching to kernel-mode signal handler
trampoline (2013-03-16).
* arch/arm/include/armv[6|7]-m/irq.h, and arch/arm/src/armv[6|7]-m/up_svcall.c:
Add support for nested system calls. In the current design, this can
happen only under one condition: When the kernel system call logic calls
back into user space in order to allocate user space memory. So it is
expected that the maximum nesting level will be only 2 (2013-03-17).
* libc/stdio/lib_sccanf.c: Correct an error in sscanf. If %n occurs in
the format statement after the input data stream has been fully
parsed, the %n format specifier will not be handled. Reported by
Lorenz Meier (and also earlier by Kate) (2013-03-17).
* drivers/serial/serial.c: Support for O_NONBLOCK was not supported
in the "upper half" serial driver. This is normally not an issue
because UART TX is almost always available, but it does become an
if the UART uses hardware flow control or if the a "lower half" is
something like the USB CDC/ACM driver that may need to block for
significant amounts of time (2013-03-18).
* arch/arm/src/armv7-h/ram_vectors.h, up_ramvec_*.c, arch/arm/src/*/*_irq.c,
and Make.defs: Add support for modifiable interrupt vectors in RAM
(2013-03-18).
* arch/arm/src/armv7-m/up_exception.S, sam3u/sam3u_vectors.S, and
lpc17xx/lpc17_vectors.S: In exception handling with CONFIG_NUTTX_KERNEL,
need to explicity set and clear the privilege bit in the CONTROL
register on return. I assumed this would be handled automatically
by the EXC_RETURN. Silly me (2013-03-18).
* arch/arm/src/lpc17_adc.c: Add a work-around for an ADC errata. From
* arch/arm/src/armv7-m/up_hardfault.c: If the PRIMASK is used to disable
interrupts, then additional logic is required in the hard fault handler
* libc/ and mm/: Directories where the same sources files are used to
build different objects in the first and second pass kernel builds need
to keep those objects in separate directories so that they are not
* fs/fat: Create an error in FAT file creation. The FAT logic was
not making a distinction between directory non-existence and file
non-existence so when it you try to create a file in a non-existent
patacongo
committed
directory, it would create a file with the name of the missing
directory. Reported by Andrew Tridgell (2013-03-30).
* Numerous files: Changed the protoypes of up_create_stack() and
up_release_stack() so that is includes a task type. Normally you
can get this type from the TCB parameter, but there are certain
conditions when the task type is not valid in the TCB when these
functions are called. Only the prototypes were changed on this
big, initial checkin. The next step will be to add logic to
allocate stacks for kernel threads from protected kernel memory
and all other task types from unprotected user memory (2013-03-20).
* arch/*/src/common/up_createstack.c, up_use_stack.c, and
up_release_stack.c: If creating or releasing the stack for a kernel
thread, use the kernel allocator so that the kernel thread stacks
are protected from user application meddling (2013-03-20).
* arch/arm/src/armv[6|7]-m/up_scall.c: Fix parameter passing for
all system call inline functions with > 3 parameters (2013-03-20)
* arch/*/src/common/up_stackframe.c and include/nuttx/arch.h: Add
and new interface to set aside memory on the stack. This will be
used at least in the kernel build to hold task arguments (2013-03-21).
* sched/sig_deliver.c: When dispatching signals to user threads,
copy the siginfo_t from the sigq to the stack. The signal queue
is allocated from kernel memory; however, the current stack is
the user's stack and the user code will be able to access the
signinfo_t data from the stack copy (2013-03-21).
* arch/arm/src/stm32: Added support for the kernel mode build
(cloned from the lpc17xx). (2013-03-21).
* configs/stme32f4discovery/kernel and scripts: Add support for
the kernel mode build on the STM32F4Discovery (2013-03-21).

contributed by Manikandan.S (2013-03-22).
* configs/zkit-arm-1769: Now supports the ST7567 LCD display

2013-03-22).
* configs/stm32f4discovery/kostest: Add a kernel mode version

* nuttx/include/nuttx, nuttx/configs/sam3u-ek, nuttx/configs/open1788,
nuttx/configs/stm32f4discovery, and nuttx/arch/arm: Complete
re-archtecting of how signals are dispatched to user-space code
in the kernel build. The original implementation was C-based
and simpler. However, the C code intermixed with SVC calls was
not properly preserving registers. The more complex, assembly
language version does not suffer from these issues. I believe
the the kernel build can now be called "feature complete"
(2013-03-23).
* binfmt/binfmt_execmodule.c: Here is a place where I forget
to update the call to sched_releasetcb() to pass the thread
type as the second parameter (2013-03-23).
* arch/arm/src/lm, kinetis, lpc32, and nuc1xx: Add kernel build
support to all ARMv7-M and ARMv6-M chips. There are no

configs/open1788/src/lpc17_sdraminitialize.c: Began testing the
Open1788 SDRAM. The SDRAM is basically functional, but there are
failures with the SDRAM is stressed by the memory test at
apps/example/ramtest (SDRAM support and the RAM test can be configured
into the base configs/open1788/nsh configuration as described in
configs/open1788/READMT.txt (2103-3-27).

* arch/arm/src/lpc17xx/lpc17_gdma.c: LPC17 DMA is code complete and
under test. Does not yet work (2013-3-30).
* fs/fat/fs_fat32dirent.c and fs_fat32util.c: Several fixes to the
FAT file system from Ronen Vainish. These fixes mostly involve the
logic to extend directory clusters for the case of long file names
but also include a few important general fixes (such as for storing
32 bit FAT values) (2013-03-31).
* arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: SD card DMA
is now functional. Thre may be some issues with DMA from CPU SRAM
which is apparently disabled in sleep mode; up_idle() always enters
sleep mode (2013-03-31).

reports LPC177x/8x GPIO registers when GPIO debug is enabled
(2013-4-05).
* arch/arm/src/Makefile: The variable NUTTX already includes
the extension $(EXEEXT). So remove the second extension
$(NUTTX)$(EXEEXT) in two places (2013-4-7).
* arch/arm/src/lpc17xx/lpc17_gpioint.c: Disable interrrupts in
lpc17_setintedge(). This logic must be atomic because it can be
re-entered before it completes enabled interrupts, sometimes
leaving the interrupts in a strange state (2013-4-7).
* arch/arm/src/lpc17_lcd.c: Rommel Marcelo got the LPC1788
framebuffer-based LCD working. Very nice! (2013-4-08).

from slcd_codec.h (2013-5-25)
* libc/misc/lib_slcdencode.c and lib_slcddecode.c: Several encoding
and decoding bug fixes (2013-5-26)
Gregory Nutt
committed
* configs/sure-pic32mx: Converted all configurations to use the
kconfig-frontends tools, cleaned up the directory structure and
naming to match some of the more recent configurations, and added
a segment LCD driver for the board. The initial checkin of the
LCD driver is just a clone of configs/pcblogic-pic32mx/src/pic32mx_lcd1602
and it not yet expected to be functional (2013-5-26).

committed
* include/nuttx/lcd/slcd_ioctl.h and all SLCD drivers: Rename geometry
structure to attributes; Move MAX contrast to attributes. Add
attribute and ioctl commands to get and set LCD brightness (2013-5-27).
* configs/sure-pic32mx/pic32mx_lcd1602.c: This driver appears to
fully functional (at least to the extent that it has been tested)
(2013-5-27).

* arch/mips/src/pic32mx/pic32mx-usbdev.c: Fix NULL packet handling in
the PIC32 USB device driver. Without this fix the CDC/ACM driver
cannot be used reliably with the PIC32 USB. With this change the
configs/sure-pic32mx/usbnsh configuration works great (2013-5-28).
* configs/sure-pic32mx/src/pic32mx_nsh.c: The NSH configurations will
support the USB monitor applications (2013-5-28).
nuttx/arch/arm/include/stm32/chip.h, src/stm32/Kconfig, src/stm32/chip.h,
and src/stm32/chip/stm32f103c_pinmap.h: STM32F103C4 and F103C8 chip
support from Laurent Latil (2013-5-28)
* configs/stm32_tiny: Add support for the STM32 Tiny development board
based on th STM32 F103C8T6 MCU (2013-5-28).
* arch/arm/src/stm32/stm32_usbdev.c: Fix an error in NULL packet
handling: If the NULL-packet needed flag ever gets set, then
it is not cleared and inifinite NULL packets result. This only
effects the CDC/ACM class and was the cause of the failure of
configs/stm32f3discovery/usbnsh configureation which works great
after this change (2013-5-29).

* drivers/usbdev/cdcacm.c and pl2303.c and include/nuttx/usb/cdcacm.h:
Change the default IN request buffer size from 64 to 96. This will
avoid requests of exactly MAXPACKET size and, hence, avoid so many
NULL packets. Also, fix the OUT request buffers size to exactly
the max packet size. It cannot be any other size (2013-5-29).
* .gitignore: Clean-up of most all .gitignore files: Make scope of
ignore to be only the current directory; Ignore .dSYM files in
directories where .exe's may be build. Also, in Makefiles,
clean .dSYM files in directories where .exe may be built (2013-5-30).
* drivers/wireless/nrf24101.c/.h and include/nuttx/wireless/nrf24101.h:
Add new driver for the wireless nRF24L01+ transceiver. From Laurent
Latil (2013-6-1).
* drivers/wireless/cc1101: Move files in the cc1101 up one directory.
From Laurent Latil (2013-6-1).
* configs/stm32_tiny: Fix nRF24L01+ driver integration for the STM32
Tiny. From Laurent Latil (2013-6-01).

to this subdirectory. Naming of registers changed from SAM3U_ to
just SAM_. This is in preparation for a SAM4L port (2013-6-2).
Gregory Nutt
committed
* arch/arm/src/sam3u: Renamed files to sam_* vs. sam3u_*.
Eliminated sam3u_internal.h; instead uses individual header
files for each SAM interface block (2013-6-2).
Gregory Nutt
committed
* arch/arm/src/stm32/stm32f20xxx_rcc.c and stm32f40xxx_rcc.c, and
configs/mikroe-stm32f4/src/up_clockconfig.c. Correct some bad
conditional compilation (CONFIG_ missing from setting name). This
affects some STM32 FLASH pre-fetch settings. From Lorenz Meier
(2013-6-2).
* arch/arm/include/sam34 and arch/arm/src/sam34: The old sam3u/
directories were renamed sam34/ to make room in the namespace for
the SAM4L (2013-6-2).
* libc/stdio/lib_dprintd.c and lib_vdprintf.c: Add dprintf() and
vdprintf() (the latter from Andrew Tridgell, 2013-6-2).
* sched/sem_holder.c: Modify assertion that is reported to cause
false alarm assertions (2013-6-2).
* arch/arm/include/sam34/sam4l_irq.h and
arch/arm/src/sam34/chip/sam4l_memorymap.h: Add interrupt and memory
map definitions for the AT91SAM4L (2013-6-3).
* arch/arm/src/sam34/chip/sam4l_vectors.h and arm/src/sam34/sam_vectors.S:
Add interrupt vector support for the SAM4L family (2013-6-3).
* arch/include/sam34/chip.h: Add chip definitions for the SAM4L
family (2013-6-3).

* arch/arm/src/stm32/stm32*_dma.*: Add a new interface function,
stm32_dmacapable() that can be used to determine if DMA is
possible from the specified memory address. From Petteri Aimonen
(2013-6-4).
* arch/arm/src/stm32/stm32_spi.c: If CONFIG_STM32_DMACAPABLE is
defined, use stm32_dmacapable() to determine if it is possible
to perform DMA from the specified address. This change is
important for the STM32 F4 which may have SPI data buffers
allocated on the stack in CCM memory which cannot support the
DMA. From Petteri Aimonen (2013-6-4).
* nuttx/arch/arm/src/sam34/sam4l_gpio.h: Created GPIO driver
header file for the SAM4L. Also renamed the SAM3U header
file to sam3u_gpio.h (2013-6-4).
* nuttx/arch/arm/src/sam34/sam4l_gpio.c: Created GPIO driver for
the SAM4L (2013-6-4).
