Adding a new target architecture variant just requires a few lines of
code in target/Config.in.arch. If you give some hints, I'm pretty sure
someone will be kind enough to help you making the necessary changes.

In 'make menuconfig', Kernel submenu, there is an option to point to
kernel patches needed for your platform.
