| 93 | MPC860 CPUs, prior to Rev C have some bugs in the silicon, which |
| 94 | require workarounds for Linux (and most other OSes to work). If you |
| 95 | get a BUG() very early in boot, this might fix the problem. For |
| 96 | more details read the document entitled "MPC860 Family Device Errata |
| 97 | Reference" on Motorola's website. This option also incurs a |
| 98 | performance hit. |
