Ideally we wouldn't have this file and put all the data into
the device tree of course but we're still lacking bindings for
that, so it's still ok for v3.5.

I think we can now probe localtimer from devicetree so you should
not need this one any more.

I'd also prefer if you could add bindings for GPT and probe
these interrupts and the GPT address from the devicetree
for the three spear platforms, that would make the code much
nicer in this area.

Can you go through this list one more time and check which ones are
still needed here? I think most of them can just get removed.

Why are the RAS control registers in a global header? It looks like you
only use them from the clock driver, so they can be moved into a local
header file there.
