Device tree aware EMAC driver
Based on BenH's earlier work, this is a new version of the EMAC driver
for the built-in ethernet found on PowerPC 4xx embedded CPUs. The
same ASIC is also found in the Axon bridge chip. This new version is
designed to work in the arch/powerpc tree, using the device tree to
probe the device, rather than the old and ugly arch/ppc OCP layer.
This driver is designed to sit alongside the old driver (that lies in
drivers/net/ibm_emac and this one in drivers/net/ibm_newemac). The
old driver is left in place to support arch/ppc until arch/ppc itself
reaches its final demise (not too long now, with luck).
This driver still has a number of things that could do with cleaning
up, but I think they can be fixed up after merging. Specifically:
- Should be adjusted to properly use the dma mapping API.
Axon needs this.
- Probe logic needs reworking, in conjuction with the general
probing code for of_platform devices. The dependencies here between
EMAC, MAL, ZMII etc. make this complicated. At present, it usually
works, because we initialize and register the sub-drivers before the
EMAC driver itself, and (being in driver code) runs after the devices
themselves have been instantiated from the device tree.
