From c74dda8b44622266feac7a0080a4302dbec052f5 Mon Sep 17 00:00:00 2001 From: Angelo Dureghello Date: Sun, 14 May 2017 21:42:27 +0200 Subject: m68k: mcf5445x: move early ddr init as board-specific For certain boot types and sbf, for V4 cpu's, an early ddr/sdram init is required. This patch moves this ddr/sdram early initalization away from start.S (to be board related).
