[U-Boot] [PATCH v3 3/3] ARM: atmel: add sama5d4ek board support
Bo Shen
voice.shen at atmel.com
Wed Oct 29 06:12:06 CET 2014
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 at atmel.com>
---
Changes in v3:
- 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
