[U-Boot] [PATCH V2 4/5] ARM: OMAP5: Add DDR changes required for OMAP543X ES2.0 SOCs

R Sricharan
2013-02-04T14:29:23Z

From: Lokesh Vutla <lokeshvutla@ti.com>

Add pre calculated timing settings of LPDDR2 and DDR3 memories
present in OMAP5430 and OMAP5432 ES2.0 versions.

Also adding the DDR pad io settings required for
OMAP543X SOCs here.
