The problem seems to be that some targets don't 8*4882a593Smuzhiyunhave CONFIG_SYS_LITTLE_ENDIAN properly set, and therefore 9*4882a593Smuzhiyunthe default -EB switch is selected. 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunLet's get rid of the default switch entirely, and fix this problem. 12*4882a593SmuzhiyunWhile this may be a hack, it is a quick solution until 13*4882a593SmuzhiyunU-Boot gets CI20 proper support. 14*4882a593Smuzhiyun 15*4882a593Smuzhiyunmake ARCH=mips CROSS_COMPILE=mips-linux-gnu- ci20_mmc 16*4882a593SmuzhiyunConfiguring for ci20_mmc - Board: ci20, Options: SPL_MMC_SUPPORT,ENV_IS_IN_MMC 17*4882a593Smuzhiyunmake 18*4882a593Smuzhiyunmake[1]: Entering directory '/home/zeta/repos/u-boot-ci20' 19*4882a593SmuzhiyunGenerating include/autoconf.mk 20*4882a593SmuzhiyunGenerating include/autoconf.mk.dep 21*4882a593Smuzhiyunmips-linux-gnu-gcc: error: may not use both -EB and -EL 22*4882a593Smuzhiyunmips-linux-gnu-gcc: error: may not use both -EB and -EL 23*4882a593SmuzhiyunGenerating include/spl-autoconf.mk 24*4882a593Smuzhiyunmips-linux-gnu-gcc: error: may not use both -EB and -EL 25*4882a593SmuzhiyunGenerating include/tpl-autoconf.mk 26*4882a593Smuzhiyunmips-linux-gnu-gcc: error: may not use both -EB and -EL 27*4882a593Smuzhiyunmips-linux-gnu-gcc -DDO_DEPS_ONLY \ 28*4882a593Smuzhiyun -g -Os -ffunction-sections -fdata-sections -D__KERNEL__ -I/home/zeta/repos/u-boot-ci20/include -fno-builtin -ffreestanding -nostdinc -isystem /home/zeta/repos/buildroot/mips/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.3.0/include -pipe -DCONFIG_MIPS -D__MIPS__ -G 0 -EB -msoft-float -fpic -mabicalls -march=mips32 -mabi=32 -DCONFIG_32BIT -mno-branch-likely -Wall -Wstrict-prototypes \ 29*4882a593Smuzhiyun -o lib/asm-offsets.s lib/asm-offsets.c -c -S 30*4882a593Smuzhiyunif [ -f arch/mips/cpu/xburst/jz4780/asm-offsets.c ];then \ 31*4882a593Smuzhiyun mips-linux-gnu-gcc -DDO_DEPS_ONLY \ 32*4882a593Smuzhiyun -g -Os -ffunction-sections -fdata-sections -D__KERNEL__ -I/home/zeta/repos/u-boot-ci20/include -fno-builtin -ffreestanding -nostdinc -isystem /home/zeta/repos/buildroot/mips/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.3.0/include -pipe -DCONFIG_MIPS -D__MIPS__ -G 0 -EB -msoft-float -fpic -mabicalls -march=mips32 -mabi=32 -DCONFIG_32BIT -mno-branch-likely -Wall -Wstrict-prototypes \ 33*4882a593Smuzhiyun -o arch/mips/cpu/xburst/jz4780/asm-offsets.s arch/mips/cpu/xburst/jz4780/asm-offsets.c -c -S; \ 34*4882a593Smuzhiyunelse \ 35*4882a593Smuzhiyun touch arch/mips/cpu/xburst/jz4780/asm-offsets.s; \ 36*4882a593Smuzhiyunfi 37*4882a593Smuzhiyunmips-linux-gnu-gcc: error: may not use both -EB and -EL 38*4882a593Smuzhiyunmake[1]: *** [Makefile:747: lib/asm-offsets.s] Error 1 39*4882a593Smuzhiyunmake[1]: *** Waiting for unfinished jobs.... 40*4882a593Smuzhiyunmake[1]: Leaving directory '/home/zeta/repos/u-boot-ci20' 41*4882a593Smuzhiyunmake: *** [.boards.depend:463: ci20_mmc] Error 2 42*4882a593Smuzhiyun 43*4882a593SmuzhiyunSigned-off-by: Ezequiel Garcia <ezequiel@collabora.com> 44*4882a593Smuzhiyun--- 45*4882a593Smuzhiyunhttps://github.com/MIPS/CI20_u-boot/pull/19 46*4882a593Smuzhiyun 47*4882a593Smuzhiyun arch/mips/config.mk | 3 --- 48*4882a593Smuzhiyun 1 file changed, 3 deletions(-) 49*4882a593Smuzhiyun 50*4882a593Smuzhiyundiff --git a/arch/mips/config.mk b/arch/mips/config.mk 51*4882a593Smuzhiyunindex c89279025507..43560abbc0e1 100644 52*4882a593Smuzhiyun--- a/arch/mips/config.mk 53*4882a593Smuzhiyun+++ b/arch/mips/config.mk 54*4882a593Smuzhiyun@@ -20,9 +20,6 @@ ifdef CONFIG_SYS_BIG_ENDIAN 55*4882a593Smuzhiyun ENDIANNESS := -EB 56*4882a593Smuzhiyun endif 57*4882a593Smuzhiyun 58*4882a593Smuzhiyun-# Default to EB if no endianess is configured 59*4882a593Smuzhiyun-ENDIANNESS ?= -EB 60*4882a593Smuzhiyun- 61*4882a593Smuzhiyun PLATFORM_CPPFLAGS += -DCONFIG_MIPS -D__MIPS__ 62*4882a593Smuzhiyun 63*4882a593Smuzhiyun # 64*4882a593Smuzhiyun-- 65*4882a593Smuzhiyun2.19.1 66*4882a593Smuzhiyun 67
