at91_set_serial_console is used to define the default console of linux.
This is already manage by the cmdline. And if the boot loader can not be
modified you can still set it by enabling the CONFIG_CMDLINE_EXTEND option.
And then the command-line arguments provided by the boot loader will be
appended to the default kernel command string.

Set ecc mode in the boards to soft as currently in the driver.

Both at91 and avr32 defines its own platform data structure for
the macb driver and both share common structures though at91
includes a currently unused phy_irq_pin. Create a common
macb_platform_data for macb that both at91 and avr32 can use. In
future we can use this to support other architectures that use the
same IP block with the macb driver.
v2: rename eth_platform_data to macb_platform_data and allow at91_ether
to share the platform data with macb.

Fix up trivial conflicts:
- arch/arm/mach-at91/board-usb-a9260.c
Merged into board-usb-a926x.c
- drivers/mtd/maps/lantiq-flash.c
add_mtd_partitions -> mtd_device_register vs changed to use
mtd_device_parse_register.
Currently atmel_nand driver used by AT91 and AVR32 calls a special callback
which return nand partition table and number of partitions. However in all
boards this callback returns just static data. So drop this callback and
make atmel_nand use partition table provided statically via platform_data.

Cleanup the YL9200 board-support file.
Other things fixed are:
- Use new-style UART initialization
- Register all LEDs as gpio_leds.
- NOR Flash error noted in comments fixed by increasing YL9200_FLASH_SIZE
- The only I2C device is the AT24C eeprom.
- Setup of NWAIT pin and programming of SMC controller for the LCD/VGA.
- Configure touchscreen interrupt pin.
