106           Saying Y here will cause the ports on an MPC8xx processor to be used

116           This enables a workaround for erratum CPU15 on MPC8xx chips.
117           This bug can cause incorrect code execution under certain
118           circumstances.  This workaround adds some overhead (a TLB miss
119           every time execution crosses a page boundary), and you may wish
120           to disable it if you have worked around the bug in the compiler
121           (by not placing conditional branches or branches to LR or CTR
122           in the last word of a page, with a target of the last cache
123           line in the next page), or if you have used some other
124           workaround.
