Ah, very nice!

Ok, looks like you are making good progress. I noticed three high-level
issues that you may want to address:

- the watchdog driver should use the generic watchdog framework rather
  than registering a misc device.
- the ehci glue can probably go away if you make very small changes
  to the generic ehci platform driver
- I don't like the way that the stmmac glue drivers are added, I thought
  we had fixed this before but I think I need to dig up old emails.
  The driver should really be a loadable module that hooks calls into
  the common code rather than being linked into one module.

I also have a plan for doing multiplatform builds of nommu kernels, 
for build testing mostly, I wouldn't expect you to run that configuration.
No need for you to address that yourself though, we'll get there.
