This release adds support for two new MCU architectures in various states of development:
This release completes the verification of the basic port for the NXP
<a href="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC3131</a> MCU
on the <a href="http://www.embeddedartists.com/products/kits/lpc3131_kit.php">Embedded Artists EA3131</a> board.
This basic port includes basic boot-up, serial console, and timer interrupts. This port
has been verified on the using the NuttX OS test and includes a working
implementation of the NuttShell (NSH).
</p>
<p>
An extended release will follow and should include SDIO-based SD card
support and device USB.

This release adds support for the SAM3U-EK development board with the
<a href="http://www.atmel.com/dyn/products/product_card_mcu.asp?part_id=4562">AT91SAM3U4E</a>.
As with most NuttX architecutre releases, the release will be rolled out in
two parts: A basic port and an extended port.
</p>
<p>
NuttX-5.1 includes the basic port for the SAM3U-EK board. This release
passes the NuttX OS test and is proven to have a valid OS implementation.
It supports the basic boot-up, serial console and timer interrupts. A
configuration to support the NuttShell is also included.
</p>
<p>
The extended port will also include support for SDIO-based SD cards and
USB device (and possible LCD support). These extensions may or may not
happen by the Nuttx 5.2 release as my plate is kind of full now.

the NXP LPC3131 MCU on the
<a href="http://www.embeddedartists.com/products/kits/lpc3131_kit.php">Embedded Artists EA3131</a>
board. That port, unfortunately has stalled due to tools issues. Those tool issues have
been resolved and I am confident that the verified basic port will be
available in NuttX-5.2.

* arch/arm/src/lpc313x and arch/arm/include/lpc313x: Added framework
to support the NXP LPC3131 MCU
* Add configs/ea3131. The LPC3131 port for the Embedded Artist EA3131
(LPC3131) is code complete and waiting for me to get hardware in
hand.
* arch/arm/src/sam3u, arch/arm/include/sam3u, and configs/sam3u-ek -
Added the basic framework needed to begin a port for the SAM3U-EK
development board.
* confgs/ea3131/tools: Added a tool to create a image suitable for
use with the LPC313x bootloader.
* configs/sam3u-3k/ostest - Completed verification of the basic NuttX
OS test for the SAM3U.
* arch/arm/src/common/up_createstack - stack was always been cleared
when it was allocated. This is a good feature for monitoring the
stack during debug, but really hurts thread start-up performance.
Clearing is now done if CONFIG_DEBUG=y only. Changes was only made
for arm, but really should be made for all architectures.
* configs/sam3u/nsh - Added NSH configuration for SAM3U
* arch/arm/src/sam3u/sam3u_pio.c - Fix an address calculation error
that caused ports B & C to get mapped to the PIOA base address.
This is an important bugfix! (a patch is available)
* arch/arm/src/lpc313x/lpc313x_boot.c - Fix an error in the vector
initialization was causing a memory fault.
* lib/lib_strtod.c - Add strtod()
* lpc3131/ea3131 - Several bring fixes submitted by David Hewson. The
lpc3131 is almost there! Thanks David!
* arch/arm/src/arm/up_head.S - Corrected backward conditional compilation
that selects if vectors are located at 0x0000:0000 or 0xffff:f000.
This fixes the last show stopper bug in the lpc313x bring-up.
* configs/ea3131/nsh - Added a NuttShell (NSH) configuration for the
EA3131.
