| On some boards the hardware configuration of the ethernet PHY can be | |

| all MII code can be omitted. Say N here if unsure or if you don't | |

| 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. | |
