Description
The default build for sparc64/ultra has become too big that when loader runs, OBP reports Fast Data Access MMU miss. Running the ctrace command reveals the call stack:
inflate_codes+444
inflate_dynamic+1c4
bootstrap+3a0
ofw_init
Where inflate_codes+444 does:
stb %o5, [%g5 + %g1]
g1: 4a4000
g5: 55c000
g5 + g1 = 0xa00000 = 10M

Looks like we need to take care of the identity mapping at higher addresses explicitly.
