Jon Master reports that QEMU refuses to load a U-Boot image built
with CONFIG_ARMV7_NONSEC, but without CONFIG_ARMV7_PSCI since
commit 5a3aae68c74e ("ARM: armv7: guard memory reserve for PSCI
with #ifdef CONFIG_ARMV7_PSCI").It looks like only PSCI that needs the Secure stack, so move the #ifdef to guard the whole of .secure_stack allocation in order not to create the empty section. Signed-off-by: Masahiro Yamada <yamada.masah...@socionext.com> Reported-by: Jon Masters <j...@redhat.com> Link: http://patchwork.ozlabs.org/patch/664025/ --- With this commit, the SECURE_MAX_SIZE check will go inside the #ifdef CONFIG_ARMV7_PSCI, so this patch is probably wrong. I am CCing Chen-Yu Tsai. He mostly expanded this linker script for PSCI work, so I hope he can suggest the correct way for fixing this problem. arch/arm/cpu/u-boot.lds | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/arch/arm/cpu/u-boot.lds b/arch/arm/cpu/u-boot.lds index 0a5fae6..37d4c60 100644 --- a/arch/arm/cpu/u-boot.lds +++ b/arch/arm/cpu/u-boot.lds @@ -74,6 +74,7 @@ SECTIONS *(._secure.data) } +#ifdef CONFIG_ARMV7_PSCI .secure_stack ALIGN(ADDR(.secure_data) + SIZEOF(.secure_data), CONSTANT(COMMONPAGESIZE)) (NOLOAD) : #ifdef __ARMV7_PSCI_STACK_IN_RAM @@ -83,10 +84,10 @@ SECTIONS #endif { KEEP(*(.__secure_stack_start)) -#ifdef CONFIG_ARMV7_PSCI + /* Skip addreses for stack */ . = . + CONFIG_ARMV7_PSCI_NR_CPUS * ARM_PSCI_STACK_SIZE; -#endif + /* Align end of stack section to page boundary */ . = ALIGN(CONSTANT(COMMONPAGESIZE)); @@ -109,6 +110,8 @@ SECTIONS . = LOADADDR(.secure_stack); #endif +#endif + .__secure_end : AT(ADDR(.__secure_end)) { *(.__secure_end) LONG(0x1d1071c); /* Must output something to reset LMA */ -- 1.9.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
