[PROJECTS] RTEMS project on ARM or kernel related.

[Ritesh Harjani]

Hi all,

Thanks to all for your promising replies. As Joel mentioned
"But we need help reviewing it, getting it ready to merge, shaking all SMP
out." I am willing to start from this point.
Please provide any links to this or Document to start off with.
git://git.rtems.org/rtems.git I will clone this git repo. hope this is the
right place I am looking to?

@ Gedare, this too is right place to start off with. I will try to
replicate the Xi's work.
@Xi Yang, can you help me out with getting the basic things in place.
Or any link/document to try this out?
