To: u-boot
We really shouldn't be overwriting bat registers with translation
enabled, especially when we're executing code using one of them
for translating the current instruction stream. Instead, disable
address translation while doing the final BAT setup.
In order to do this, setup_bats has to move back to asm code,
because we require translation to be enabled to have a stack for
C code. The yucky thing about that is that the assembler doesn't
like ULL so we have to switch to using HIGH/LOW pairs for
physical addresses that are > 32 bits in length.
