Well I can boot Debian on my 1136 r0p1 (no v6k) using a v6/v7 kernel, so the
lack of MMU shouldn't change that. The main issue was booting the same
kernel on an A15, which resulted in speculative interrupt acks on the GIC
(fix sitting in rmk's tree [ARM: 7954/1: mm: remove remaining domain support
from ARMv6]).
