These are some hackish patches to make the Ethernet driver work somehow
on this arm core.
The flash driver is not working, so we removed the nvram reading, this
should be changed after we have a flash driver.
The mdelay(1) is a ugly workaround for this arm chip, this seams to be a dma problem.
The PHY says it is not connected by default, just ignore it.
