+ * 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
