The main aim of this patchset is to add the GPIOAMSEL register to the PL061 GPIO module. I've converted the PL061 to VMState format first, though, because I didn't really feel like adding a new field/version to an old-style save/load format device...
Notes: the old vmstate format for pl061 is 32 bits per register on the wire despite being only 8 bits in the struct. I opted to widen the struct member fields to 32 bits as the least unpalatable of the various possible ways to deal with this in VMState format. The GPIOAMSEL register is TI/Stellaris specific, but we leave it in the ARM PL061 to match all the other Stellaris specific registers. It's also only present on newer Stellaris chips, but common init code typically tries to write to it anyway. Since it doesn't do anything in the model there doesn't seem any point trying to distinguish between revisions where it reads-as-written and revisions where it is unimplemented and will RAZ/WI. These patches plus Engin's one for the RCC2 register are enough for the example binary from http://www.keil.com/download/docs/345.asp to boot and at least get as far as drawing to the screen (although there may still be some issues with networking).
