The AT91CAP9 revC CPU has a few differences over the previous,
revB CPU which was distributed in small quantities only (revA was
an internal Atmel product only).

This patch adds the detection routines to recognize the different
AT91CAP9 revisions (based on the PMC subsystem version number), and
uses them to:
	- activate a workaround for the external interrupts levels
	  (on revB CPUs)
	- set the UDPHS_BYPASS bit (on revB CPUs)
	- set AT91_GPBR register address to the correct offset
	  (0xfffffd50 on revB, 0xfffffd60 on revC)

For debugging usage, the CPU revision can be found in /proc/cpuinfo
on the 'Revision' line.

This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch)
where it has been tested for the last 6 months.

Convert the SAM9 and CAP9 board-specific files to make use of the
sam9_smc_configure() method to configure the memory-controller for
external peripherals.

The following boards have been modified:
 cam60 : NAND
 cap9adk : NAND, NOR
 qil-a9260 : NAND
 sam9-l9260 : NAND
 sam9260ek : NAND
 sam9261ek : DM9000 Ethernet, NAND
 sam9263 : NAND
 sam9g20ek : NAND
 sam9rlek : NAND
 usb-a9260 : NAND
 usb-a9263 .: NAND

In at91_add_device_nand(), do not configure the Static Memory
controller with specific timing values.
The *_devices.c files are board independent, and the SMC timing values
are specific to the NAND devices that are installed on the board.
The board-specific files are now responsible for configuring the
Static Memory controller (if the don't want to leave it up to a
bootloader).

Add a structure 'sam9_smc_config' and function sam9_smc_configure() to
allow the board-specific files to specify the configuration of the
Static Memory Controller per chip-select.  This allows the board file
to specify timings for NAND flash, NOR flash or other external
peripherals.

This functionality can be used for all the SAM9 and CAP9 processors.
(the AT91RM9200 has a different memory-controller)
This patch is based on similar code in the AVR32 architecture.

Update to use the asm/sections.h header rather than declaring these

This avoids confusion with platform specific DMA implementations in
mach/dma.h
Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Since 8d5796d2, we have allowed
PAGE_OFFSET to be configurable, so a constant virtual address
for MAX_DMA_ADDRESS is buggy.  It should be defined in terms of
PAGE_OFFSET rather than a constant virtual address.

Move the definition of MAX_DMA_ADDRESS from mach/dma.h to mach/memory.h,
thereby placing it along side its relative, ISA_DMA_THRESHOLD.
