The i.MX53 boards m53evk, mx53cx9020 and mx53loco are using the exact same dram initialization code, which uses 'static uint32_t mx53_dram_size[2];' in dram_init(), dram_init_banksize() and get_effective_memsize() to avoid multiple calls to get_ram_size(). This series replaces the static variable with multiple calls to get_ram_size() and moves the shared code into arch/arm/mach-imx/mx5/. The first patch fixes cx9020. The next patch moves that code to a common place to be reused by m53evk and mx53loco with the next patches. Changes in v2: - move dram initialization into common location - reuse fixed dram initialization for m53evk and mx53loco Patrick Bruenn (4): arm: imx: cx9020: remove usage of mx53_dram_size arm: imx: cx9020: move dram init into common place arm: imx: m53evk: remove usage of mx53_dram_size arm: imx: mx53loco: remove usage of mx53_dram_size arch/arm/mach-imx/mx5/Makefile | 5 ++++ arch/arm/mach-imx/mx5/mx53_dram.c | 45 ++++++++++++++++++++++++++++++++++ board/aries/m53evk/m53evk.c | 39 ----------------------------- board/beckhoff/mx53cx9020/mx53cx9020.c | 39 ----------------------------- board/freescale/mx53loco/mx53loco.c | 39 ----------------------------- 5 files changed, 50 insertions(+), 117 deletions(-) create mode 100644 arch/arm/mach-imx/mx5/mx53_dram.c
