Introduce a new level of portability: boards.

Browse Source 
Since we don't support Flattened Device Trees yet (and they don't solve all the issues), we need a place to hole board-specific config, which are different even though we use U-Boot on ARM. Things like cpu & mmu type...
U-Boot doesn't really help us there anyway, it only passes a few board infos (RAM banks & the bill), and optionally other stuff if we fake a linux kernel or netbsd loader, but still not enough. FDT support isn't available for ARM in U-Boot yet either. So for now, and likely for stuff we can't get from FDT, we'll put board-specific config there.
Unlike desktop machines were we want a single kernel per arch, we'd rather have the kernel built for a single board without having to handle detecting mmu type at boot and switching calls like I did on m68k.
