Great! As you may be aware, we have recently added ARMv7 support which you
might want to use as an example. The architecture code is in
src/arch/armv7, the CPU code is in
src/cpu/samsung/{exynos5250,exynos5-common}, and the first ARM motherboard
target is in src/mainboard/google/snow.

The ARM stuff is still under active development, and we are still making
changes to code that was imported from another codebase (u-boot). But
overall it works and we are able to load a payload and boot Linux.
