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().

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
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(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:
git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91

Replace the 'is_b' variable with 'slot_b' in at91_mmc_data.
Also add the new 'chipselect' variable for CF/PCMCIA and 'bus_width_16'
variable for NAND.
This (and previous patches) will unfortunately break the current MMC,
USB Gadget and PCMCIA drivers. Updates and fixes for those drivers will
be submitted to the various subsystem maintainers.

This patch converts the old CONFIG_MTD_PHYSMAP_ options to the new
physmap API by creating a physmap platform device for the NOR flash

This patch makes the AT91 gpio.c support processor-generic (AT91RM9200
and AT91SAM9xxx). The GPIO controllers supported by a particular AT91
processor are defined in the processor-specific file and are registered
with gpio.c at startup.

Patch from Andrew Victor
This patch updates the support for the Atmel DK and EK boards.
The changes include:
1. Use the new at91_uart_config structure and device registration
functions for the UARTs.
2. Registration of I2C and SPI platform devices.
3. The USB Device pullup line is connected to reset, so multidrive needs
to be enabled on the line. [Patch from David Brownell].

Patch from Andrew Victor
On the Atmel AT91RM9200-DK and -EK boards, a pin is used to control
whether the card socket is used for a DataFlash Card or an MMC/SD card.
We now default to MMC/SD in the configuration files.
