74xx_7xx, mpc8xx, ppc4xx -- called regardless of CONFIG_HAS_ETHn
mpc512x -- called only based on HAS_ETH0
mpc8260, mpc83xx, mpc85xx, mpc86xx -- called if HAS_ETH0 || HAS_ETH1  
|| HAS_ETH2 || HAS_ETH3

With ETH3 being the max today.

We have a part (p4080) in the works with 8 interfaces (its unlikely  
we'll have support for all 8 in u-boot, but do want to be ablity to  
set mac addresses for all 8.)
