What Tom is doing at the moment is to rewrite boot0 and onwards, dodging
the openness issues of the existing bootloader.

The cpu runs BROM on reset.

BROM loads SPL from the boot media. SPL configures DRAM and what else
needs to be initialized for the CPU to function like what we know of as
a CPU.

SPL then loads another program. For flexibility we want some kind of
boot loader, but may just as well load a kernel directly if you like,
assuming all the hardware setup we need fits in SPL.

The discussion on which full bootloader to use is secondary. For now we
use u-boot as it's already available for A10. It's easy to replace
