From 5b34691ff87821891375b28ec5bcf5154575a735 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 27 Jul 2009 07:42:37 +0200 Subject: [PATCH] ppc4xx: Kilauea: Fix SDRAM init in NAND booting version DDR2 Auto-calibration needs to be disabled on the NAND booting PPC4xx targets. Otherwise the configured fixed init values for some DDR2 controller registers (e.g. RQDC) are not initialized at all resulting in a non working SDRAM.
