AT91RM9200 specific directory in kernel source tree

Hi,

I would like the specific directory in kernel source for this processor. Say if I have intel pxa processor, I have a directory arch/mach-pxa named for this. I hope this is the BSP part

Similary, is there any thing for atmel's AT91RM9200.

Generally, the kernel does not have per-processor directories, only per-architecture.

What are you looking to achieve?

Did you try to install a patch already?
