stmmac-socfpga breakage in arm-soc

[Arnd Bergmann]

Hi Dinh,

I just merged your stmmac socfpga glue driver with Ack from
David Miller, but then found multiple issues with it. I've
attempted to fix them up in an untested patch below, which
I could apply on top, if everyone thinks this is a good idea.

If we can't get agreement on this, it's probably better if
we revery your stmmac series for now and try to get it
right for 3.16.

On a more general note about the stmmac driver, I think it
should be restructured into a base 'library' driver and
multiple front-ends per SoC or interface (PCI, platform-generic,
sun7i, socfpga, sti, spear, ...) that can be built as
modules, like we do for other drivers that get reused a lot
with smaller variations.

Any comments?
