[PATCH v2 00/07] ARM: shmobile: Suspend on non-SMP for r8a7790/r8a7791

[Magnus Damm]

ARM: shmobile: Suspend on non-SMP for r8a7790/r8a7791 (V2)

[PATCH v2 01/07] ARM: shmobile: Allow use of boot code for non-SMP case
[PATCH v2 02/07] ARM: shmobile: Adjust APMU code to build for non-SMP
[PATCH v2 03/07] ARM: shmobile: Use __init for APMU suspend init function
[PATCH v2 04/07] ARM: shmobile: Move r8a7790 reset code to pm-r8a7790.c
[PATCH v2 05/07] ARM: shmobile: Allow r8a7790 to build non-SMP APMU code
[PATCH v2 06/07] ARM: shmobile: Move r8a7791 reset code to pm-r8a7791.c
[PATCH v2 07/07] ARM: shmobile: Allow r8a7791 to build non-SMP APMU code

These patches update mach-shmobile and r8a7790/r8a7791 to allow build of
early boot code and APMU power management code in case of CONFIG_SMP=n.

The reason for this change is to allow use of Suspend-to-RAM for recent
SoCs like R-Car Gen2 with simplified kernel configuration such as when
SMP is disabled. Power management code like CPUFreq, CPUIdle and
Suspend-to-RAM should work regardless of what kind of CONFIG_SMP
setting the user decides.

 Changes since V1:
 - Dropped V1 patch 6, 7, 8 - needs more discussions how to tie in UP case
 - Moved V1 patch 5 to V2 patch 3
 - Added r8a7791 code at end of series

Hi Magnus

I tested these patches. Test result is below:

[Test environment]
 -lager / koelsch
 -tag:renesas-devel-v3.15-rc8-20140605v3

[Test command]
Suspend to RAM command
 #echo enabled > /sys/class/tty/ttySC6/power/wakeup
 #echo mem > /sys/power/state

[Test results]
 -lager(SMP)		:OK
 -lager(non-SMP)	:OK
 -koelsch(SMP)		:OK
 -koelsch(non-SMP)	:OK
