Gong Qianyu Qianyu.Gong at freescale.com
Wed Nov 11 10:58:36 CET 2015


Reuse dts files from ls1043a linux kernel. Some parts in dts files
may not be needed by U-Boot.

Signed-off-by: Gong Qianyu <Qianyu.Gong at freescale.com>

V4:
 - No change.
V3:
 - Modified the dts file according to ls1043a upstreaming linux kernel.
V2:
 - New Patch.
