Kernel patches for board support

Hi,

I'm in the process of adding board support for the Friendly ARM mini2440 boards to buildroot, but I'm a bit stuck with how to handle the kernel patch. Is there an accepted way of doing this? The patch I have will apply against any 2.6.32 version.

Hopefully when I'm done it'll be good enough for submission to buildroot, but I'm a bit of a newbe at this!

Paul.
