[GSOC2009]GUMSTIX(PXA255) BSP for RTEMS

[xi yang]

Hi, I work for project of GSOC2009. Here is a sample BSP for Gumstix
with clock, uart, timer support.
gumstix_bsp.patch is generated by cvs diff -uN
You need place gumstix.cfg to ./make/custom/
Extract gumstix.tar.gz to c/src/lib/libbsp/arm/
Extract pxa255.tar.gz  to c/src/lib/libcpu/arm/
gumstix.skyeye is configure file for skyeye simulator.
With below patch for current version from SVN of skyeye project, you
can use skeyey to run GUMSTIX bsp by ./skyeye -c gumstix.skyeye -e
hello.exe (Please notice that when you execute ticker.exe, you have to
wait for a long time since one tick of skyeye simulator is more slower
than real hardware)

Here is Skyeye patch(Maybe then have fixed in SVN)
