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.
Signed-off-by: Wenyou Yang wenyou.yang@microchip.com ---
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 code from the board/atmel/common folder.
