[PATCH 0/3] ARM: zynq: ARCH_MULTIPLATFORM support

Michal-

Here's an attempt at supporting ARCH_MULTIPLATFORM on Zynq.  I've gotten
a multiplatform kernel building and booting on the zc702, although I
haven't tried to boot the same image on another non-Zynq board, due to
lack of available hardware.

It would be super awesome if this set could land in 3.8, but I know
we're running out of time there.  I wouldn't be too heartbroken if it
didn't make it.

This patchset is on top of your arm-next branch and with the
debug_ll_init support patch @ arm-soc/devel/debug_ll_init.

Patch 1 drops the early TTC mapping.  It is not necessary, since the TTC
driver now supports pulling mapping info from the device tree.

Patch 2 converts zynq to use the debug_ll_init() infrastructure slated
to go into 3.8.

Patch 3 is the bulk of the set, moving around logic around within
mach-zynq/include, and setting up the necessary build magic to get Zynq
building w/ CONFIG_ARCH_MULTIPLATFORM.

Thanks,
   Josh
