nuttx-0.3.17 2008-10-28 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
	* Incorporate patch "[2164503] nuttx-0.3.16 does not build for ARM with USB disabled"
	* Reduced the amount of memory reserved for USB serial control requests.  It
	  was unnecessarily large.
	* Added LPC214x SPI1 driver to interface with MMC on mcu123.com board.
	* Added a simple SPI-based MMC/SD block driver
	* NSH: Add LPC214x-specific support to NSH; NSH now mounts any SD cards in the slot.
	* FAT: Fix access to unaligned 32-bit values in partion table (start sector &amp; size)
	* Fixed a problem with a un-initialized variable in the USB serial driver.
	* Added USB storage NXP LPC214x configuration
	* Added a test for USB storage under examples/usbstorage
	* Fixed a bug in the LPC214x USB driver: It was not properly clearing a HALTed
	  endpoints (other than EP) on receipt of CLEAR FEATURES request.
	* Added USB storage class device side driver (BBB)
	* Fixed a bug in the LPC214x USB driver: It was not properly handling request buffers
	  larger then the endpoint's max packet (DM320 driver also fixed, untested)
	* Added logic to the USB device interface:  A bit is needed to force the driver to
	  to terminate an IN transfer with a short packet (zero-length if necessary).
	* Fix an error in the NXP LPC214x USB device driver that was causing corruption of
	  the request queue (M320 driver also fixed, untested)
	* Correct another error in the NXP LPC214x USB device driver that caused read failures
	  when the request buffer size was larger than maxpacket.
	* Numerous corrections/extensions to the USB tracing logic included in 0.3.16 (but
	  not integrated until 0.3.17)
	* Fixed another bug in the NXP LPC214x USB device driver:  After a stalled endpoint
	  is resumed (view CLEAR FEATURE), we must restart the IN (outgoing) queue.

pascal-0.1.2 2008-02-10 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;

	* Add logic to build and link with the ZDS-II toolchain
	  use with the z16f.
	* Make sure that POFF header structures are aligned
	* Standardized POFF file format to big-endian
	* Break up large switch statements to lower complexity
	  and eliminate a compiler bug
	* Changes so that runtime compiles with SDCC.

buildroot-0.1.0 2007-03-09 &lt;spudmonkey@racsa.co.cr&gt

	* Support for arm-elf toolchain

nuttx-0.3.18 2008-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
	* Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711
	  board (STR71x testing is stalled because I have been unable to get OpenOCD to
	  communicate with my JTAG wiggler on Linux).
	* Fix race condition workaround delay in LPC214X SPI logic.  It the cause of the very
	  bad MMC/SD performance.
	* Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board (this is a work in progress)

pascal-0.1.3 2008-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;

buildroot-0.1.1 2008-xx-xx &lt;spudmonkey@racsa.co.cr&gt;

	* Support for m68k-elf and m68hc11 toolchain
	* Add patch to build older binutils with newer Texinfo version
	* Add support for SH-1 toolchain
