just a small note: mii does NOT depend on generic DMA working (only MMC does so far):

The Ethernet MAC controller uses a dedicated DMA controller to transfer data between the Ethernet MAC module and the host memory.

It is very similar to the DMA descriptors of the LCDC.
And the jz4730 ethernet driver has code to do the setup of the buffers.

So I am working a little (while I should do other urgent things) on
polishing the ethernet driver:

1. replace kernel threads by delayed_worker
2. replace printk/prerror() with dev_err()
3. fix whitespace and coding style
4. (try to) register access without strange macros with BASE
