[PATCH v4 0/8] SMP support for CNS3xxx + some SMP SCU cleanups

Hello everyone,

This is a reincarnation of my old series that was posted some time
ago, i.e. http://www.spinics.net/lists/arm-kernel/msg94291.html

The main change is that boot protocol routines were split into
its own file, i.e. smp_scu_boot.c. And now there are all platforms
converted to the common SCU routines (where possible).

Russell suggested to get rid of the holding pen thing, I believe
this is doable, but for now I don't want to change code behaviour.
Just consolidate it as much as possible.

For convenience, the patches are available in GIT repository (based
on Russell's devel tree):

git://git.infradead.org/users/cbou/linux-cns3xxx.git smp

Diffstat looks quite good, I think. Especially, considering that
the series contains SMP addition for a platform, :-)
