From 7ee37d0e0c06730f99926bdb05781bc0111c0161 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 16 Feb 2018 01:33:27 +0100 Subject: ARM: rmobile: Convert Porter to SPL Due to size limitations of the MERAM, switch U-Boot to SPL. The SPL is loaded by the SPI_LOADER into MERAM and then loads U-Boot proper into DRAM. This way U-Boot can freely grow in size in DRAM, as there is plenty of it. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu --- NOTE: To update U-Boot, first install u-boot.img to 0x140000 in SPI NOR, then use the Minimon to flash u-boot-spl.srec using ls,2,e6304000. To generate u-boot-spl.srec, use objcopy: arm-linux-gnueabi-objcopy -O srec spl/u-boot-spl u-boot-spl.srec --- include/configs/porter.h | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) (limited to 'include/configs/porter.h') diff --git a/include/configs/porter.h b/include/configs/porter.h index b4a317f..758ed21 100644 --- a/include/configs/porter.h +++ b/include/configs/porter.h @@ -16,12 +16,8 @@ #include "rcar-gen2-common.h" -#if defined(CONFIG_ARCH_RMOBILE_EXTRAM_BOOT) -#define CONFIG_SYS_INIT_SP_ADDR 0x7023FFFC -#else -#define CONFIG_SYS_INIT_SP_ADDR 0xE633fffC -#endif -#define STACK_AREA_SIZE 0xC000 +#define CONFIG_SYS_INIT_SP_ADDR 0x4f000000 +#define STACK_AREA_SIZE 0x00100000 #define LOW_LEVEL_MERAM_STACK \ (CONFIG_SYS_INIT_SP_ADDR + STACK_AREA_SIZE - 4) @@ -67,4 +63,11 @@ #define CONFIG_SYS_I2C_POWERIC_ADDR 0x58 /* da9063 */ +/* SPL support */ +#define CONFIG_SPL_TEXT_BASE 0xe6304000 +#define CONFIG_SPL_STACK 0xe6340000 +#define CONFIG_SPL_MAX_SIZE 0x40000 +#define CONFIG_SPL_SPI_LOAD +#define CONFIG_SYS_SPI_U_BOOT_OFFS 0x140000 + #endif /* __PORTER_H */ -- cgit v1.1
