From 70616df2bfbb4de675b93aa85e8aec744346fede Mon Sep 17 00:00:00 2001 From: Sandy Patterson Date: Mon, 29 Aug 2016 07:31:17 -0400 Subject: [PATCH] Enable ROCKCHIP_SPL_BACK_TO_BROM for rock2 board Rock2 has been tested with back to brom feature. The tricky part is that with this feature the default environment is inside u-boot, and it's defined for every rk3288 board independetly. So I just changed it for rock2 here if ROCKCHIP_SPL_BACK_TO_BROM. Solve by moving environment after u-boot before 1M boundary Signed-off-by: Sandy Patterson Acked-by: Simon Glass --- configs/rock2_defconfig | 2 ++ include/configs/rock2.h | 9 +++++++++ 2 files changed, 11 insertions(+) diff --git a/configs/rock2_defconfig b/configs/rock2_defconfig index fc9ff78943..036125689a 100644 --- a/configs/rock2_defconfig +++ b/configs/rock2_defconfig @@ -7,6 +7,8 @@ CONFIG_SPL_STACK_R_ADDR=0x80000 CONFIG_DEFAULT_DEVICE_TREE="rk3288-rock2-square" CONFIG_SPL_STACK_R=y CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN=0x2000 +# CONFIG_SPL_MMC_SUPPORT is not set +CONFIG_ROCKCHIP_SPL_BACK_TO_BROM=y CONFIG_HUSH_PARSER=y CONFIG_CMD_BOOTZ=y # CONFIG_CMD_IMLS is not set diff --git a/include/configs/rock2.h b/include/configs/rock2.h index ee924c3816..99d69155d2 100644 --- a/include/configs/rock2.h +++ b/include/configs/rock2.h @@ -16,11 +16,20 @@ #define CONFIG_ENV_IS_IN_MMC #define CONFIG_SYS_MMC_ENV_DEV 0 + +#ifdef CONFIG_ROCKCHIP_SPL_BACK_TO_BROM +/* SPL @ 32k for 34k + * u-boot directly after @ 68k for 400k or so + * ENV @ 992k + */ +#define CONFIG_ENV_OFFSET ((1024-32) * 1024) +#else /* SPL @ 32k for ~36k * ENV @ 96k * u-boot @ 128K */ #define CONFIG_ENV_OFFSET (96 * 1024) +#endif #define CONFIG_SYS_WHITE_ON_BLACK #define CONFIG_CONSOLE_SCROLL_LINES 10 -- 2.25.1
