		* ABSTRACT:
		*
		* The PXA270 processor comes with a bunch of hardware on its silicon.
		* Not all of this hardware can be used at the same time and not all
		* is routed to module's connectors. Also it depends on the baseboard, what
		* kind of hardware can be used in which way.
		* -> So this file supports the main devices on the CPU card only!
		* Refer pcm990-baseboard.c how to extend this features to get a full
		* blown system with many common interfaces.
		*
		* The PCM-027 supports the following interfaces through its connectors and
		* will be used in pcm990-baseboard.c:
		*
		* - LCD support
		* - MMC support
		* - IDE/CF card
		* - FFUART
		* - BTUART
		* - IRUART
		* - AC97
		* - SSP
		* - SSP3
		*
		* Claimed GPIOs:
		* GPIO0 -> IRQ input from RTC
		* GPIO2 -> SYS_ENA*)
		* GPIO3 -> PWR_SCL
		* GPIO4 -> PWR_SDA
		* GPIO5 -> PowerCap0*)
		* GPIO6 -> PowerCap1*)
		* GPIO7 -> PowerCap2*)
		* GPIO8 -> PowerCap3*)
		* GPIO15 -> /CS1
		* GPIO20 -> /CS2
		* GPIO21 -> /CS3
		* GPIO33 -> /CS5 network controller select
		* GPIO52 -> IRQ from network controller
		* GPIO78 -> /CS2
		* GPIO80 -> /CS4
		* GPIO90 -> LED0
		* GPIO91 -> LED1
		* GPIO114 -> IRQ from CAN controller
		* GPIO117 -> SCL
		* GPIO118 -> SDA
		*
		* *) CPU internal use only
