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.
