The rk3288 spl size is very close to 32KB while the rk3288 bootrom has the limitation of maximum size of SPL is 32KB. After apply this patch, the SPL size will exceed 32KB if we do not enable macro CONFIG_ROCKCHIP_SPL_BACK_TO_BROM and disable CONFIG_SPL_MMC_SUPPORT.
This patch has test with 2GB DDR3 and 2GB/4GB LPDDR3. V2 add patch to clean some source code size for some rk3288 board to make the SPL size in the 32KB limitation. Changes in v3: - move the config into defconfig file - add error report and return value when error happen - add comments for stride and address bits. Changes in v2: - update code for OF_PLATDATA enabled - bug fix for ddrconfig Kever Yang (3): rk3288: config change for enable dram capacity auto-detect. rk3288: sdram: auto-detect the capacity dts: rk3288: remove node in dmc which not need anymore arch/arm/dts/rk3288-evb.dts | 3 - arch/arm/dts/rk3288-fennec.dts | 3 - arch/arm/dts/rk3288-firefly.dts | 2 - arch/arm/dts/rk3288-miniarm.dts | 3 - arch/arm/dts/rk3288-popmetal.dts | 3 - arch/arm/dts/rk3288-rock2-square.dts | 2 - arch/arm/dts/rk3288-veyron.dtsi | 2 - arch/arm/include/asm/arch-rockchip/sdram.h | 15 ++ arch/arm/mach-rockchip/rk3288/sdram_rk3288.c | 272 ++++++++++++++++++++++----- configs/evb-rk3288_defconfig | 1 + configs/fennec-rk3288_defconfig | 1 + configs/miniarm-rk3288_defconfig | 1 + configs/popmetal-rk3288_defconfig | 1 + 13 files changed, 249 insertions(+), 60 deletions(-) -- 1.9.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
