This patch adds baseboard support for the phyCORE-PXA270 development kit (aka PCM-990). This example shows how to use some phyCORE-PXA270 CPU module features on a baseboard in a standard manner. It could be used as a starting point for custom baseboard development. V2: After comments by Eric Miao: - IRQ chained handler fixed - video/graphic support moved to separate patch - ifdef/endif hell reduced ;-) V3: After comments by Russell King - initialise the mmci platform data statically V4: After comments by Russell King - wrong return value in pcm990_mci_init() fixed Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
