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 Motorola's website. This option also incurs a
|
|
|
|
|
performance hit.
|
|
|
|
|
|
|
|
|
|
If in doubt, say N here.
