* drivers/usbdev/Kconfig, arch/arm/src/sam34/Kconfig, and
drivers/usbdev/usbmsc_scsi.c: If DCD can support queuing of stall
requests, then the USB MSC stall work around delays are not necessary
(2014-3-20).

* net/netdev_findbyaddr.c: Skip network devices that are in the
"down" state. It does not make sense to consider an address match
with a "down" device. From Brennan Ashton (2014-3-20).
* configs/sam4e-ek/usbnsh: Add a NSH configuration that uses the
NSH console (2014-3-22).
* arch/arm/src/stm32/stm32_eth.c: Add IGMP hashing support. From
Manuel Stühn (2014-3-24).

from Manuel Stühn (2014-3-24).

* arch/arm/src/sam34: Add missing HSCMI configuration settings to
Kconfig; update naming to include SAM34_ (2014-3-24).
* configs/sam4e-ek/include/board.h: Update HSMCI timing to use the
CLKODD bit (2014-3-24).
Gregory Nutt

* drivers/include/mtd/Kconfig, sector512.c, and include/nuttx/mtd/mtd.h:
Add a new MTD driver that can be used to contain another driver and
force its apparent sector size to be 512 bytes (2014-3-24).
* arch/arm/src/sam34/sam_lowputc.c sam_serial.c: Fix a mysterious
multithreading bug that can log up the serial port (2014-3-14).
* drivers/usbdev/Kconfig, usbmsc.c, usbmsc.h, and usbmsc_scsi.c:
Redesign threading module used with the USB MSC driver. It was using
pthreads before and these were changed to a kernel thread. The reason
for this has to do with task grouping: A pthread is a memory of the
group of the task that started it. A kernel thread is independent of
the task that started in (other than knowing it as the parent). This
allows me to remove so kludge logic to "deparent" the pthread on
startup (2014-3-25).
* tools/astyle.sh: A code formatting tool from Lorenz Meier. This
tool should do a better job than the old tools/indent.sh tool
* arch/arm/src/sam_hsmci.c and sam_spi.c: Add support to invalidate
cached memory if the CMCC is enabled (not yet tested, 2014-3-26).
* arch/arm/src/sam_spi.c: Add logic to handle SPI word widths > 8
(also untested on initial checkin, 2014-3-26).
* configs/sam4e-ek: All configurations updated to run with 120MHz

CPU speed and with the CMCC enabled. Calibrated delay loop
(2014-3-26).
* drivers/lcd/Kconfig: Add missing configuration for the MIO283QT-9A
LCD. Reported by Toby Duckworth (2014-3-27).
* arch/arm/include/sama5/chip.h and arch/arm/src/sama5/Kconfig: Add
support for the SAMA5D36 (2014-3-28).
Gregory Nutt
committed
* libc/strings/lib_strncpy.c: Change ordering of test and copy. Logic
would have failed if n=0; one byte was always copying before testing
for the end of the copy.
* nuttx/configs/sama5d3-xplained/: Add a board support configuration
for the Atmel SAMA5D3 Xplaiend board. The initial check in is not
finished. For example, it still builds to run out of NOR FLASH but
the SAMA5D Xlpained has no NOR FLASH (2013-4-28).
Gregory Nutt
committed
* arch/arm/src/sama5/sam_pmc.c and .h: Add functions to calculate
PLLACK, PCK, and MCK frequencies given the main clock frequency
(2014-3-29).
Gregory Nutt
committed
* configs/sama5d*/include/board.h, board_sdram.h, and other files:
When booting from SDRAM, we need to query the PMC registers (using
the functions in sam_pmc.c) to determine the MCK, PCK, etc. We assume
that the MCK input clock is well known main crystal oscillator
frequency (2014-3-29).
Gregory Nutt
committed
* configs/sama5d3x-ek: Change all configuration names to board-
specific names so that this are no name collisions with other
boards that have similar configuration variables (2013-3-30).
Gregory Nutt
committed
* configs/nuttx/compiler.h: Add macro UNUSED() that can be used
to eliminate warnings about variables that are set to values
that are not used (2014-3-30).
Gregory Nutt
committed
* arch/arm/src/sama5/sam_hsmci_clkciv.c: Remove HSCMI-related
functions that did not belong in sam_pmc.c and give them their
own file (2014-3-30).
* arch/arm/src/sama5/sam_boot.c: Fix some backward conditional
compilation (2014-3-30).
Gregory Nutt
committed
* libc/stdio/lib_sccanf.c: Fix a counting error in the return
value from sscanf(). Noted by kfrolov. Also, sscanf() should
return EOF if no values were converted (2014-3-30).
* include/time.h and sched/clock_settime(): Add support for
CLOCK_REALTIME. From Macs N (2014-3-31).
* libc/stdio/lib_ferror.c, lib_fread.c, lib_libfflush.c,
lib_libfread.c, and lib_libfwrite.c: Finish incomplete support
for ferror(). From Macs N (2014-3-14).
Gregory Nutt
committed
* libc/stdio/lib_ftell.c: Fix a logic error in ftell(). It was
simply using the file offset and did not take into account data
buffered in memory. From Macs N (2013-3-31).
* Add CONFIG_CLOCK_MONOTONIC that case used to disable CLOCK_MONOTONIC
for a smaller footprint (2013-3-31).
* sched/Kconfig: Menu has gotten too long. And another layer of
menuing in order to simplify this layer (2014-3-31).
* arch/arm/src/sama5_boot.c: Fix double mapping of SDRAM when executing
out of SDRAM. In this case, the SDRAM was already mapping in
arm_head.S (2014-3-31).
* arch/arm/src/sama5/chip/sam_dbgu.h: Add SAMA5D3 DBGU definition
header file (2014-3031).
Gregory Nutt
committed
* arch/arm/src/sama5/sam_dbgu.c and .h: Add support for the SAMA5D3
DBGU (2014-4-1).
* configs/sama5d3-xplained/nsh: Configurations now use the DBGU for
the serial console (instead of USART1) (2014-4-1).
* libc/stdio/lib_sccanf.c: Use stroul() vs strol() with %u format
otherwise, range of values is restricted because of sign bit
from kfrolov (2014-4-2).
* arch/arm/src/sama5/sam_boot.c, sam_irq.c, chip/sama5d3x_memorymap.h:
When running from SDRAM, vectors must lie in SRAM (2014-4-2).
Gregory Nutt
committed
* arch/arm/src/armv7-a/arm_head.S and cache.h: On start-up, make
certain the the MMU and caches are disabled (probably un-necessary)
(2014-4-2).
* arch/arm/src/sama5/sam_boot.c: If we have to copy vectors, then
make sure to clean the DCache to be sure that the copied vectors are
in the physical RAM (2014-4-2).
* arch/arm/src/sama5/sam_irq.c: After we modify the AXI MATRIX, make
sure to invalidate all caches and TLBs (probably un-necessary)
(2014-4-2).
Gregory Nutt
committed
* arch/arm/src/sama5/sam_irq.c: Set the VBAR register to zero. If
were started by a bootloader (vs. a RESET), then the VBAR register
may not be in its reset state (zero, 2014-4-3).
* arch/arm/src/sama5/sam_boot.c, sam_irq.c, and chip/sama5d3x_memorymap.h:
When booting from SDRAM, don't relocated vectors to ISRAM. Instead,
just set the VBAR register to address of the vectors in SDRAM.

committed
* arch/arm/src/sama5/sam_clockconfig.c: BMS Fixed to match what the HW
does. From David Sidrane (2014-4-3).
* arch/arm/src/sama5/Kconfig, sam_boot.c, andsam_clockconfig.c: On some
hardware, reconfiguring the PLL while executing out of NOR FLASH causes
crashes. This was fixed by David Sidrane by implementing RAM functions.
The killer code is copied and executed from ISRAM and the crash is
avoided (2014-4-3).
* configs/sama5d3-xplained/Kconfig and include/board*.h;
configs/sama5d3x-ek/Kconfig and include/board*.h: Add support for
528MHz CPU clock (2014-4-3).
* arch/arm/src/sama5/Make.defs: Fix a build error that occurs when
only USB device tracing is enabled (2014-4-4).
* Documentation/UsbTrace.html: Add some discussion of the USB monitor
(2014-4-4).
Gregory Nutt
committed
* nuttx/arch/arm/src/armv7-a/mmu.h: Bufferable bit did not do what
I thought it was going to do. Result was the NOR FLASH accesses
were very slow (2014-4-3).
Gregory Nutt
committed
* arch/arm/src/sama5/sam_udphs.c: Fix a case where received status
was not clear, causing OUT SETUP commands to fail (2014-4-6).
Gregory Nutt
committed
* arch/arm/src/tiva/tiva_syscontrol.c: Add logic for TM4C125GXL based
on logic from Daniel Carvalho with modifications. I think the
LM4F120 may have broken before as well(?). In any event, the LM4F120
also works well with this chanage (2014-4-7).
