From daebb796ff5a91f3185c7653abcb97c3a0a228f3 Mon Sep 17 00:00:00 2001 From: Patrick Bruenn Date: Tue, 16 Jan 2018 07:59:02 +0100 Subject: arm: imx: cx9020: move dram init into common place Move dram_init(), dram_init_banksize() and get_effective_memsize() to arch/arm/mach-imx/mx5/mx53_dram.c, where it can be reused by m53evk and mx53loco.
