Tue Oct 27 01:59:57 CET 2015
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.
