If we get an #ifdef maze, this is an indication we need to re-think how
gt64260 is done. My suggestion is a struct that the platform/*_setup.c
file can give to the eth driver somehow that specifies all this stuff.

I would really like the gt64260 eth and serial drivers to be useable on
mips also.. so we need to find someone with a mips 64240 board..

FYI, the gt eth driver is completely busticated for SMP. I managed to get
zuma's mpsc driver working on SMP by turning on snooping. (this may be the
'wrong' thing to do , but it works for now)

I agree 100% on this.

The only thing we *HAVE* to find out from the firmware is the MAC address.
