Enable option for big endian configuration but it is not used too much that's why it is completely untested. By supporting this system there is a need to define LITTLE/BIG endian Kconfig options to pass -EL/-EB flags. Full command line for u-boot.elf recreation looks like this: microblazeel-xilinx-linux-gnu-objcopy -I binary -B microblaze \ -O elf32-microblazeel u-boot.bin u-boot-elf.o Signed-off-by: Michal Simek Link: https://lore.kernel.org/r/7e242a519fcd1c693b9103c5599b515af555ca43.1655299267.git.michal.simek@amd.com --- diff --git a/arch/Kconfig b/arch/Kconfig index 4851300e9b..02de32f9c7 100644 --- a/arch/Kconfig +++ b/arch/Kconfig @@ -448,7 +448,7 @@ source "arch/riscv/Kconfig" source "board/keymile/Kconfig" -if MIPS +if MIPS || MICROBLAZE choice prompt "Endianness selection" @@ -460,11 +460,11 @@ choice config SYS_BIG_ENDIAN bool "Big endian" - depends on SUPPORTS_BIG_ENDIAN + depends on (SUPPORTS_BIG_ENDIAN && MIPS) || MICROBLAZE config SYS_LITTLE_ENDIAN bool "Little endian" - depends on SUPPORTS_LITTLE_ENDIAN + depends on (SUPPORTS_LITTLE_ENDIAN && MIPS) || MICROBLAZE endchoice diff --git a/arch/microblaze/config.mk b/arch/microblaze/config.mk index de5b97e719..3e84a832fc 100644 --- a/arch/microblaze/config.mk +++ b/arch/microblaze/config.mk @@ -16,3 +16,9 @@ LDFLAGS_FINAL += --gc-sections ifeq ($(CONFIG_SPL_BUILD),) PLATFORM_CPPFLAGS += -fPIC endif + +ifeq ($(CONFIG_SYS_LITTLE_ENDIAN),y) +PLATFORM_ELFFLAGS += -B microblaze $(OBJCOPYFLAGS) -O elf32-microblazeel +else +PLATFORM_ELFFLAGS += -B microblaze $(OBJCOPYFLAGS) -O elf32-microblaze +endif diff --git a/configs/microblaze-generic_defconfig b/configs/microblaze-generic_defconfig index 7994110b28..35e32466bd 100644 --- a/configs/microblaze-generic_defconfig +++ b/configs/microblaze-generic_defconfig @@ -14,6 +14,7 @@ CONFIG_XILINX_MICROBLAZE0_USE_BARREL=1 CONFIG_XILINX_MICROBLAZE0_USE_DIV=1 CONFIG_XILINX_MICROBLAZE0_USE_HW_MUL=1 CONFIG_DISTRO_DEFAULTS=y +CONFIG_REMAKE_ELF=y CONFIG_FIT=y CONFIG_FIT_VERBOSE=y CONFIG_BOOTDELAY=-1
