[U-Boot] [PATCH] dra7xx: Add dra74_evm_defconfig using CONFIG_DM

Mugunthan V N mugunthanvnm at ti.com
Tue Sep 22 15:15:12 CEST 2015


Import various DT files for dra7-evm from Linux Kernel v4.2
Add config file for this board, enable DM and DM_GPIO

Signed-off-by: Mugunthan V N <mugunthanvnm at ti.com>
