I'm porting U-Boot to a PPC405GPr board of our own design,
and I'm having trouble getting the ethernet working.
Specifically, when I try to do anything network related,
it hangs in ppc_4xx_eth_init. I added some test prints
and find that I'm getting an un-clearable error interrupt.
I've added some test prints to dump the obvious registers,
here's a snippet:

XXXX Entering ppc_4xx_eth_init
ENET Speed is 10 Mbps - HALF duplex connection
XXXX about to enable interrupts...

MAL error occured.... ISR = 0 UIC = 7f0000  MAL_DEF = 2e0000  MAL_ERR=
260000
XXXX Entering ppc_4xx_eth_init
XXXX about to enable interrupts...
XXXX Leaving ppc_4xx_eth_init

MAL error occured.... ISR = 0 UIC = 7f0000  MAL_DEF = 2e0000  MAL_ERR=
260000
XXXX Entering ppc_4xx_eth_init
XXXX about to enable interrupts...
XXXX Leaving ppc_4xx_eth_init

... and so on. It is looping infinitely on the un-cleared
error interrupt.  I'm struggling w/ PHY/MII/MAL learning
curves, as well as U-Boot learning, so clues welcome.
