Please provide generic concepts about porting Linux to ARM.
Hi,
you can find examples from kernel source tree.
LXR linux/arch/arm/
There are many platforms sit in the directory above. Normally, you don't need to do much regarding processor itself unless you are doing SoC enabling work. I presume you just want to make Linux run on the board you designed. If it is the case, have a look at LXR linux/arch/arm/mach-realview/ It will show how to setup memory map, peripherals etc.
Hope this helps.
