* 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
