From e049b772ae21e6698b65ebb3bc3afc61c8b13f39 Mon Sep 17 00:00:00 2001 From: Tom Rini <trini@konsulko.com> Date: Thu, 2 Apr 2015 16:01:33 -0400 Subject: [PATCH] am33xx/ddr.c: Fix regression on DDR2 platforms Back in fc46bae a "clean up" was introduced that intended to reconcile some of the AM335x codepaths based on how AM43xx operates. Unfortunately this introduced a regression on the DDR2 platforms. This was un-noticed on DDR3 (everything except for Beaglebone White) as we had already populated sdram_config correctly in sequence. This change brings us back to the older behavior and is fine on all platforms. Tested on Beaglebone White, Beaglebone Black and AM335x GP EVM Reported-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Tom Rini <trini@konsulko.com> --- arch/arm/cpu/armv7/am33xx/ddr.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/cpu/armv7/am33xx/ddr.c b/arch/arm/cpu/armv7/am33xx/ddr.c index 85cceae152..f5b16b4b72 100644 --- a/arch/arm/cpu/armv7/am33xx/ddr.c +++ b/arch/arm/cpu/armv7/am33xx/ddr.c @@ -164,9 +164,9 @@ void config_sdram(const struct emif_regs *regs, int nr) writel(regs->ref_ctrl, &emif_reg[nr]->emif_sdram_ref_ctrl); writel(regs->ref_ctrl, &emif_reg[nr]->emif_sdram_ref_ctrl_shdw); } - writel(regs->sdram_config, &emif_reg[nr]->emif_sdram_config); writel(regs->ref_ctrl, &emif_reg[nr]->emif_sdram_ref_ctrl); writel(regs->ref_ctrl, &emif_reg[nr]->emif_sdram_ref_ctrl_shdw); + writel(regs->sdram_config, &emif_reg[nr]->emif_sdram_config); } /** -- 2.39.5
