From 5614e71b4956c579cd4419b958b33fa6316eaa92 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 30 Sep 2013 09:22:09 -0700 Subject: Driver/DDR: Moving Freescale DDR driver to a common driver Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs. The similar DDR controllers will be used for ARM-based SoCs.

These changes are backward compatible. Some fields are removed for newer DDR controllers. Writing to those fields are safely ignored. TIMING_CFG_2 register is fixed. Additive latency is added to RD_TO_PRE automatically. It was a misunderstanding in commit c360ceac.
