It was using the faraday driver, not the aspeednic one. I fixed this
up and re-pushed (along with a bunch of cleanups - you may find the
history was rewritten, sorry).

aspeednic.c has a bunch of #defines I copied from the board files when
bringing up witherspoon which forces the driver into NC-SI mode. I
suggest we use the ftgmac100 driver for platforms with a dedicated
phy, and aspeednic for NC-SI. The goal is to add a NC-SI library to
u-boot so ftgmac100 can be a NC-SI driver in a similar fashion to the
kernel. Gavin will work on that next week.

After doing this work today I still need to re-check it boots on the
ast2500 systems. Once I've done that I'll push to openbmc/u-boot.

Cheers,

Joel
