I've been developing a new BSP since May 2009.
We are porting the csb337 to the new BSP csb637. It is an ARM9 processor
from ATMEL (the AT91RM9200).
We want this BSP in the 4.10 version.
It is good work to do and it is not so easy if you want it a little more
complete. I think the basic things are: UART at least for testing, and the
mininum OS functionality.
We based on the existing BSP and change somethings to the new one. I am
delevoping also some drivers to complete the BSP, but i think it is a harder
task to do.
As xu ray said the quicker way to do is create a new folder and change based
on the existing closer BSP.
