From b97476965bf292c13074e01de4bd39253de0ef66 Mon Sep 17 00:00:00 2001 From: Vikas Manocha Date: Sun, 28 May 2017 12:55:10 -0700 Subject: stm32: stm32f7: add spl build support This commit supports booting from stm32 internal nor flash. spl U-Boot initializes the sdram memory, copies next image (e.g. standard U-Boot) to sdram & then jumps to entry point. Here are the flash memory addresses for U-Boot-spl & standard U-Boot: - spl U-Boot : 0x0800_0000 - standard U-Boot : 0x0800_8000 To compile u-boot without spl: Remove SUPPORT_SPL configuration (arch/arm/mach-stm32/Kconfig) Signed-off-by: Vikas Manocha [trini: Rework Kconfig logic a bit] Signed-off-by: Tom Rini --- arch/arm/mach-stm32/Kconfig | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'arch/arm/mach-stm32') diff --git a/arch/arm/mach-stm32/Kconfig b/arch/arm/mach-stm32/Kconfig index ec6b3ff2df..a3390d0bfd 100644 --- a/arch/arm/mach-stm32/Kconfig +++ b/arch/arm/mach-stm32/Kconfig @@ -8,6 +8,23 @@ config STM32F1 config STM32F7 bool "stm32f7 family" + select SUPPORT_SPL + select SPL + select SPL_CLK + select SPL_DM + select SPL_DM_SEQ_ALIAS + select SPL_DRIVERS_MISC_SUPPORT + select SPL_GPIO_SUPPORT + select SPL_LIBCOMMON_SUPPORT + select SPL_LIBGENERIC_SUPPORT + select SPL_MTD_SUPPORT + select SPL_OF_CONTROL + select SPL_OF_LIBFDT + select SPL_OF_TRANSLATE + select SPL_PINCTRL + select SPL_RAM + select SPL_SERIAL_SUPPORT + select SPL_SYS_MALLOC_SIMPLE source "arch/arm/mach-stm32/stm32f4/Kconfig" source "arch/arm/mach-stm32/stm32f1/Kconfig" -- cgit v1.2.1
