ARM: mach-shmobile: r8a7779 SMP support V3
This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
