From: Bo Shen @ 2014-11-10 7:24 UTC (permalink / raw)
To: u-boot
The code for this board supports following features:
- Boot media support: NAND flash/SD card/SPI flash
- Support LCD display
- Support ethernet
- Support USB mass storage
Signed-off-by: Bo Shen <voice.shen@atmel.com>

Changes in v4:
- rebase to the mainline master (11ada92)
- Select CPU_V7 in Kconfig.
- Drop CONFIG_ARMV7 in board head file.
Series-changes: 3
- Rewrite the h32mxdiv related code according to Andreas's suggestion.
Series-changes: 2
- Add sama5d4_devices.c to hold soc related code (e.g: get_cpu_name)
- rewrite the clock with H32MXDIV
Changes in v2: None
