From: Wenyou Yang <wenyou.yang@atmel.com>

The SAMA5D27-SiP (System in Package) integrates the SAMA5D2
with 1Gbit DDR2-SDRAM in a single package.

The SAMA5D27 SOM1 embeds a 64Mbit QSPI flash, KSZ8081 Phy and
Mac-address EEPROM.

 - Drop the applied patches.

Changes in v4:
 - Rebase the uboot/master (84a4206).
 - Remove the default config file for the spiflash.
 - Integrate the following patches into this patch series.
   1./ [PATCH v2 0/3] board: atmel: Set the ethernet mac address from eeprom
   2./ [PATCH 1/7] lib: at91: Add logo files used by API from DM_VIDEO
   3./ [PATCH 2/7] atmel: common: Add function to display via DM_VIDEO's API
   4./ [PATCH] board: sama5d2_xplained: Make SPL work on spiflash
 - Remove the dependency on [PATCH 0/5] configs: at91: Remove value of CONFIG_SYS_EXTRA_OPTIONS option.

Changes in v3:
 - Rebase on the PATCH: Atmel PIT timer driver and Remove CONFIG_SYS_EXTRA_OPTIONS.
 - Use the new Atmel PIT timer driver.
 - Remove "SAMA5D2" from CONFIG_SYS_EXTRA_OPTIONS options.
 - Move CONFIG_ENV_IS_IN_FAT to Kconfig.

Changes in v2:
 - Add the reviewed-by tag.
 - Add the help in Kconfig to describe the board and peripherals.
 - Add the code to display the company's logo and board information.
 - Replace the code to set the ethernet mac address with the common
