  To: u-boot

The board supports following features:
 - Boot media support: SD card/e.MMC/SPI flash,
 - Support LCD display (optional, disabled by default),
 - Support ethernet,
 - Support USB mass storage.

The patch is based on the following patches sent in mailing list.
	[PATCH] gpio: atmel: Add the PIO4 driver support
	[PATCH] arm: at91: Change the Chip ID registers' addresses
	[PATCH v3] mmc: atmel: Add atmel sdhci support
	[PATCH v2] arm: at91: clock: Add the generated clock support

Changes in v2:
 1./ re-order SAMA5D2 statements alphabetically.
 2./ remove redundant "Unknown CPU type".
 3./ rework sama5d2's macros.
 4./ remove some #ifdef before functions.
 5./ move CONFIG_CMD_SF to Kconfig.
 6./ remove NAND macros from config file.
 7./ CONFIG_BOOTCOMMAND for sf uses defines in at91-sama5_common.h.
