From a49716aa7cda96f5e8cd15e57587da7a99f9e330 Mon Sep 17 00:00:00 2001 From: Allen Martin Date: Fri, 31 Aug 2012 08:30:11 +0000 Subject: [PATCH] tegra20: move SDRAM param save to later in boot Move warmboot_save_sdram_params() to later in the boot sequence. This code relies on devicetree to get the address of the memory controller and with upcoming changes for SPL boot it gets called early in the boot process when devicetree is not initialized yet.
