Great stuff!

Regarding the question about the directory, is there going to be any
shared code with the files present in mach-mvebu, e.g. the SMP support
that I assume is planned for a later point?

If there is shared code, it's probably best to have it in here. Otherwise
I don't care either way: We have precedent for fairly unrelated platforms
(ev2+shmobile, or the mach-bcm) being in the same directory for practical
reasons, and you can also create an almost empty directory now as we are
likely going to consolidate all "trivial" platforms in the future. Once
the l2x0 and clock init code as well as the early mapping has been
addressed, there won't be any platform code left.
