What would it take to implement cache support for mips? The u-boot mips
cache code seems quite straight forward. With cache support you could
use several drivers as they are and wouldn't have to introduce
physical/virtual translations. I'm afraid these translations will be
broken quite soon as they get tested only on Mips.
