[MPC8xx] Initial MMU too low

[LEROY christophe]

Hello,

When I build a kernel with DEBUG_LOCK_ALLOC set, I get a kernel which 
has __bss_stop above the C0800000 limit, and then I get a bad page 
exception during the zeroize of the __bss at startup, because the 
initial MMU only maps the first 8Mbytes.

What can I do to fix that ?
