| 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 |
| need link status reports. |

| 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. |
