[U-Boot] [PATCH] net: Add option to disable fibre on M88E1111 PHY for PPC4xx
By defining CONFIG_M88E1111_DISABLE_FIBRE boards can configure the M88E1111 PYH to disable fibre. This is needed for an upcoming PPC460GT based board, which has fibre/copper auto-selection enabled by default. This doesn't seem to work. So we disable fibre in the PHY register.

I don't mean to be pedantic, but unless this is a Fibre Channel link (and it isn't), the appropriate spelling is 'FIBER'. I say this reluctantly, having been raised using British/European spelling...

Thanks. I'll send an updated patch version tomorrow.
