[ARM] 4744/1: pcm027: add support for phyCORE-PXA270 CPU module
This patch adds main support for the generic phyCORE-PXA270 CPU module (aka PCM-027). Its as generic as possible to support any kind of baseboard. Note: Neither the CPU module nor the pcm027.c implementation can work without a baseboard support. Baseboard support can be added by the PCM-990 or any custom variant. V2: After comments by Eric Miao: - Currently unsupported devices moved into separate patch - direct call of baseboard initialisation V3: After comments by Russell King - sort include files - setting RTC bit for power control removed - style problems fixed (discovered by checkpatch.pl) Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
