[U-Boot] [PATCH v4 1/2] imx: mx6dlarm2: Add support for i.MX6DL arm2 DDR3 board

Ye.Li B37916 at freescale.com
Mon Sep 29 17:26:28 CEST 2014 

This patch adds the i.MX6DL arm2 board support. The i.MX6DL ARM2
shared the same board with i.MX6Q ARM2 board since the i.MX6DL is
pin-pin compatible with i.MX6Q.

The patch also support the DDR 32-BIT mode option. Please define
CONFIG_DDR_32BIT in the board configure file to enable DDR 32-BIT
mode.But due to the board design, it's 64bit DDR buswidth physically,
so, if you CONFIG_DDR_32BIT, the DDR memory size will be half of it.
