From 382de4a7e9278cdd086897ef94b02d35cbd8aa5e Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 26 Jun 2019 13:51:46 +0900 Subject: arm64: add an option to switch visibility of CONFIG_SYS_INIT_SP_BSS_OFFSET By default, CONFIG_SYS_INIT_SP_BSS_OFFSET was made invisible by not giving a prompt to it. The only way to define it is to hard-code an extra entry in SoC/board Kconfig, like arch/arm/mach-tegra/tegra{186,210}/Kconfig. Add a prompt to it in order to allow defconfig files to specify the value of CONFIG_SYS_INIT_SP_BSS_OFFSET. With this, CONFIG_SYS_INIT_SP_BSS_OFFSET would become always visible. So, we need a new bool option to turn it off by default. I move the 'default 524288' to the common place. This value is not too big, but is big enough to avoid the overwrap of DT in most platforms. If 512KB is not a suitable choice for your platform, you can change it from your defconfig or menuconfig etc. Signed-off-by: Masahiro Yamada Acked-by: Stephen Warren --- Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index 516260f46d..73fdf70cdd 100644 --- a/Makefile +++ b/Makefile @@ -874,7 +874,7 @@ ifneq ($(CONFIG_BUILD_TARGET),) ALL-y += $(CONFIG_BUILD_TARGET:"%"=%) endif -ifneq ($(CONFIG_SYS_INIT_SP_BSS_OFFSET),) +ifdef CONFIG_INIT_SP_RELATIVE ALL-y += init_sp_bss_offset_check endif @@ -1155,7 +1155,7 @@ binary_size_check: u-boot-nodtb.bin FORCE fi \ fi -ifneq ($(CONFIG_SYS_INIT_SP_BSS_OFFSET),) +ifdef CONFIG_INIT_SP_RELATIVE ifneq ($(CONFIG_SYS_MALLOC_F_LEN),) subtract_sys_malloc_f_len = space=$$(($${space} - $(CONFIG_SYS_MALLOC_F_LEN))) else -- cgit
