barebox is not neccessary, Thomas and I just merged SoC init to always
map on KW, Dove, and A370/XP. It is in a very early stage (console-only)
and will take some time to actually boot linux. And we have SoC
specific init that can set CP15 there.

Dove is difficult because u-boot always remaps and never sets the bit
in CP15 _but_ doesn't hang on writing wrong addresses. So remap by
writing to 0xd0.. will do no harm.
