help
|

MPC860 CPUs, prior to Rev C have some bugs in the silicon, which
|
|
require workarounds for Linux (and most other OSes to work). If you
|
|
get a BUG() very early in boot, this might fix the problem. For
|
|
more details read the document entitled "MPC860 Family Device Errata
|
|
Reference" on Freescale's website. This option also incurs a
|
|
performance hit.

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.
