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. Arnd
