[RFC PATCH 0/3] Per SoC descriptor

[Marc Zyngier]

This is my first stab at an idea that has floated around for a while,
which is to have a per-soc descriptor containing most of the SoC
specific operations, which should clear the path a bit more towards
the single zImage holy grail. It's as far as possible from being
perfect, but I thought I'd share it as early as possible and see what
people think of it.

This first patch series introduces the arm_soc_desc structure, adds
per-soc SMP and CPU hotplug operations, and converts both RealView and
VExpress to this new scheme.

There's a number of things I'm happy with yet in that patch series:
- the per-soc descriptor init is ugly
- all descriptors are kept around forever

I plan to address those in the future (if this patch series has any!).

It's been tested on VExpress (A5 and A15) and RealView EB-11MP.
