| 91 | bool "CPU6 Silicon Errata (860 Pre Rev. C)" | |
| 92 | help | |
| 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. | |
| 99 | ||
| 100 | If in doubt, say N here. | |
