Structs called at91_nand_data where renamed to atmel_nand_data
and configs called *MTD_NAND_AT91* where renamed to
*MTD_NAND_ATMEL*. This was unfortunately not done consistently,
causing NAND chips not being initialised on several ARM boards.
I am aware that the author of the original change did not rename
MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
to keep naming consistency.
This patch was only tested on a MACH_SAM9_L9260, as this is the
only ARM board I have to my disposal.

The AT91CAP9 processor includes the same Static Memory Controller
(SMC) peripheral as the SAM9 processors, but replaces the SDRAM
Controller with a DDR/SDR Controller (DDRSDRC).
This patch splits the existing
include/asm-arm/arch-at91/at91sam926x_mc.h into at91sam9_sdramc.h and
at91sam9_smc.h.
It also adds an at91cap9_ddrsdr.h for the DDRSDRC controller.

The AT91 I2C driver is currently marked as "broken" due to hardware
issues. This patch enables AT91-based platforms to also use the
bitbanged GPIO for I2C.
This updates platform setup logic (setting up an i2c-gpio device
using the same pins as the i2c-at91 device, unless only the BROKEN
driver is enabled).
Also make use of the new-style initialization of I2C devices using
i2c_register_board_info().

Andrew Morton found a section mismatch warning in x86_64 triggered by a
wrongly placed __initdata marker.
git grep "struct __initdata" revealed that board-sam9260.c had the same
problem.
This patch fixes this by placing the __initdata marker correct. It was
checked with objdump that the variable was moved to .init.data by this
change.
Fixed an unrelated section mismatch warning while touching the file.
Both changes are only compile tested but obvious correct.

The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.
These changes are:
* The system peripheral I/O region we remap has increased from
0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
* The increased I/O region forces changes to entry-macro.S and
debug-macro.S due to ARM's limited immediate offset addressing
modes.
* Maximum number of GPIO banks increases to 5.
* 2 MMC controllers so the board-setup code needs to specify which
controller it wishes to use when calling at91_add_device_mmc().

Now that Linux includes support for the Atmel AT91SAM9260 and

(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.
The following git commands should be run BEFORE applying this patch:

Fix build failure of AT91SAM9260.
The AT91RM9200 ethernet driver (at91_ether.c) stores platform data in a
"struct at91_eth_data" structure, but the AT91SAM9260 (and AT91SAM9263)
ethernet driver (macb.c) [developed on the AVR32 architecture] expects a
"struct eth_platform_data".
Since the platform data of the two drivers is very similar, we continue
to use the "struct at91_eth_data" for all AT91 processors but add a
#define eth_platform_data at91_eth_data
in board.h to keep the MACB driver happy.
