[U-Boot] [PATCH v4 12/15] config: Move smdkv310 to use common exynos4 file

Simon Glass sjg at chromium.org
Mon Sep 29 03:18:51 CEST 2014


Most of the smdkv310 features are common with other exynos4 boards. To
permit easier addition of driver model support, use the common file and
add a device tree file.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v4:
- Rebase on top of master (CONFIG_OF settings moved to Kconfig)

Changes in v3: None
Changes in v2:
- Leave in a few configs which are not in fact common to all boards
