Most of it is not board-specific, but platform-specific. This driver handles 
all 4xx EMAC variants and there are quite a lot. But basically you are 
correct.

In net/eth.c? It can't get overwritten then.

I could use board_eth_init() as a common PPC4xx platform code. But I would 
loose the chance being able to implement a "real" board specific 
board_eth_init() for some boards in the future then.
