- get a BUG() very early in boot, this might fix the problem. For
- more details read the document entitled "MPC860 Family Device Errata

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