From aa09a071c3295011816c0e2f18532f61bc8b74f3 Mon Sep 17 00:00:00 2001 From: Michael Trimarchi Date: Wed, 31 Oct 2018 20:03:16 +0100 Subject: [PATCH] sunxi: Fix memory 2-rank initialization for a33 cpu When we initialize the memory we need to autodetect rank and size but this can happen only if we send the proper reset to both memory module including cke signal. For this reason we need initialize the physical on both channel because we need to presume that both are connected. This way let the CLKE to be activated at the right time with the memory reset coming from the cpu Signed-off-by: Michael Trimarchi Acked-by: Maxime Ripard --- arch/arm/mach-sunxi/dram_sun8i_a33.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/mach-sunxi/dram_sun8i_a33.c b/arch/arm/mach-sunxi/dram_sun8i_a33.c index d9aa0c6..1da2727 100644 --- a/arch/arm/mach-sunxi/dram_sun8i_a33.c +++ b/arch/arm/mach-sunxi/dram_sun8i_a33.c @@ -334,7 +334,7 @@ unsigned long sunxi_dram_init(void) struct dram_para para = { .cs1 = 0, .bank = 1, - .rank = 1, + .rank = 2, .rows = 15, .bus_width = 16, .page_size = 2048, -- 2.7.4
