create the Cortex-A5 support (2013-7-19).

* arch/Kconfig: Attempt at generic external memory configuration is not
flexible enough, especially for the SAMA5. Move external memory
configuration options from arch/Kconfig to
arch/arm/src/lpc17xx/Kconfig, lpc31xx/Kconfig, sam34/Kconfig, and
sama5/Kconfig and renamed each from CONFIG_ARCH_ to, for example,
CONFIG_LPC31_. This renaming also affect many defconfig files
(2013-7-24).
* arch/arm/src/sama5/Kconfig and sam_allocateheap.c: Set up

configured as a UART or not. And this is for all CPUS, not just
SAM3/4 (2013-7-24).
Gregory Nutt

* arch/arm/src/arm/up_head.S and arch/arm/src/armv7-a/arm_head.S:
Fix a bug (uninitialized register error) that crept in the ARM9
boot-up code several years ago and was cloned into the Cortex-A5
code. Obviously no one has used the ARM9 NuttX port for years!
* Many files: Finally... I changed the naming of configuration
variables like CONFIG_DRAM_ to CONFIG_RAM_. This has bothered
me for a long time since most boards don't have DRAM. The more
generic RAM naming should not produce so much cognitive dissonance
(2013-7-26).
* configs/sama5d3x-ek/hello: Added a tiny hello world configuration
to simplify bring up of the SAMA5 (it will probably be removed
later) (2013-7-26).
* The sama5d3x-ek/hello now runs correctly (2013-7-28).
Gregory Nutt

* configs/sama5d3x-ek/src/sam_norflash.c: Add board specific

timing BEFORE increasing the main clock (2013-7-29).
Gregory Nutt
committed
* configs/sama5d3-ek/norboot and src/nor_main.c: The norboot
configuration to help debug NuttX in NOR flash. It runs
out of ISRAM, configures NOR FLASH, then waits for you to
break in with a debugger to start the program in NOR FLASH
(2013-7-29).
* arch/arm/src/armv7-a/arm_cache.S: Separate the bigger cache
operations into separater files (2013-7-29).

Gregory Nutt
committed
* arch/arm/src/sama5/arm_head.S: Setup page table mappings for
all of .text, .bss, .data, stacks and heap before enabling
the MMU and caching. This is safer because it avoids the
caching issues (and much less redundant) (2013-8-1)
* arch/arm/src/sama5/chip/sam_mpddrc.h: Add DDR controller
registers definitions for the SAMA5 (2013-8-1).
* nuttx/configs/sama5d3x-ek/src/sam_sdram.c: Add logic which

greater than or equal to 2GB (2013-8-2).
* arch/arm/src/sama5/sam_boot.c: Boot logic now initially
configures DRAM as strongly ordered so that it can be initialized.
After initialization, the page table entries are modified so
that DRAM is fully cache-able (2018-8-2).

SAMA5 DMA controller (2013-8-3).
* arch/arm/src/sama5/sam_dmac.c and sam_dmac.h: Add support for the
SAMA5 DMAC controllers. Initial check-in is untested and is a
straight leverage from the SAM3/4 (2013-8-4).
* arch/arm/src/sama5/sam_spi.c, sam_spi.h, and chip/sam_spi.h:
Leverage SPI support from SAM/3/4. Initial check-in is untested

(2013-8-5).
* arch/arm/src/sam34/sam_spi.c: Corrected an error in the SAM3/4
SPI driver while testing the SAMA5 SPI driver: If CONFIG_SPI_OWNBUS

(2013-8-5).
* configs/sama5d3x-ek/src/sam_at25.c: Move AT25 initialization logic

use the kconfig-frontends tool. From Max Holtzberg (2013-8-12).
* includes/nuttx/usb/usbhost.h, et al: Continued changes to the USB
host interface to support multiple downstream ports. When a class
is disconnected, it needs to provide the FunctionAddress to the
USB HCD disconnect method so that the HCD will know which port
is being disconnected (2013-8-12).

STM32 F3 I2C fixes from John Wharington (2013-8-13).
* nuttx/arch/arm/src/sama5/sam_serial.c: Fix a re-entrancy problem
in up_putc(). I think all architectures have this re-entrancy
than can result in serial interrupt being disabled, but I have only
seen the symptom on SAMA5 (2013-8-13).

* includes/nuttx/usb/usbhost.h and many other affected files: Separate
wait() and enumerate() methods from struct usbhost_driver_s and move
to new interface, struct usbhost_connection_s. This is part of the
necessary restructuring of the USB host interface to support multiple
root hub ports (2013-8-13).
Gregory Nutt
committed
* arch/arm/src/sama5/sam_ohci.c: Major restructuring of the driver due
in order to handle multiple root hub ports. Basically instead of one
driver structure with an arrayof root hub port structures, there is no
one container structure with an array of driver structures, one for
each root hub port. The advantage is that each class->driver call not
passes information associated with the RHport implicitly. The klugey,
procedural alternative was to add the function address to every
interface method (which I started to do but backed above) (2013-8-13).

* include/nuttx/usb/usbhost.h, drivers/usbhost/usbhost_enumerate.c, and
all USB host drivers: Added a new driver method: getdevinfo. This
method is intended to get various information about the connected device,
but currently returns only the device speed. The device speed is
necessary by usbhost_enumerate in order to set a credible initial EP0
max packetsize. High speed needs 64 bytes, low speed needs 8 bytes,
and full speed can handle almost any size (2013-8-26).

has not yet been configured. Verified on CDC/ACM. Corresponding
changes made to pl2303, but untested (2013-9-5).

may not be detected when the connection is lost before it has been
accepted (from Max Holtzberg) (2013-9-6).
* configs/sama5d3x-ek/demo: Add a new NSH configuration. The
original NSH configuration will be a simple platform for testing
individual features; the demo configuration will be a more complex
platform for demonstrating multiple interacting features (2013-9-6).

* drivers/usbhost/usbhost_storage.c: Correct a reference counting
error: When an MSC device transfer fails while waiting for
UnitTestReady (see 2013-9-9), the reference count was not being
decremented. The end result is a memory leak (2013-9-10).

PHYs (identified with ETH0 and ETH1) (2013-9-17).
* net/Kconfig and drivers/net/Kconfig: Move PHY selections from
net/Kconfig to drivers/net/Kconfig where they belong. Add the previx
ETH0_ to each PHY selection. And a new configuration
CONFIG_NETDEV_MULTINIC that can be set to enable support for multiple

Fatah (2013-9-17).
* configs/: Lots of defconfig files changes. A consequence of the
above renaming and moving of the PHY configuration settings is
that the you now also have to set CONFIG_NETDEVICES=y if you
need to set a PHY configuration (2013-9-17).

that does not work. A divider of 5 does. Why? (2013-9-19).
* Several USB device driver files: Change naming of SELFPOWERED
and REMOTEWAKEUP to avoid name collisions. Prepend the name
of the driver (for example CDCACM_SELFPOWERED) (201309-20).
* configs/sama5d3x-ek/nsh and demo: Increase the number of pre-allocated
watchdog timers. The default number of 4 was easily being exhausted
