This patch breaks the build with MACH_MMP_DT=y in 3.4-rc2 for me: MACH_MMP_DT selects CPU_PXA168 which selects CPU_32v5, which results in: armv7-unknown-linux-gnueabi-gcc -Wp,-MD,arch/arm/mm/.dma-mapping.o.d -nostdinc -isystem /opt/crosstool/gcc-4.6.0/lib/gcc/armv7-unknown-linux-gnueabi/4.6.0/include -I/home/cjb/git/olpc-kernel/arch/arm/include -Iarch/arm/include/generated -Iinclude -I/home/cjb/git/olpc-kernel/include -include /home/cjb/git/olpc-kernel/include/linux/kconfig.h -I/home/cjb/git/olpc-kernel/arch/arm/mm -Iarch/arm/mm -D__KERNEL__ -mlittle-endian -I/home/cjb/git/olpc-kernel/arch/arm/mach-mmp/include -I/home/cjb/git/olpc-kernel/arch/arm/plat-pxa/include -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-delete-null-pointer-checks -Os -marm -fno-dwarf2-cfi-asm -mabi=aapcs-linux -mno-thumb-interwork -funwind-tables -D__LINUX_ARM_ARCH__=5 -march=armv5te -msoft-float -Uarm -Wframe-larger-than=1024 -fno-stack-protector -Wno-unused-but-set-variable -fomit-frame-pointer -g -Wdeclaration-after-statement -Wno-pointer -sign -fno-strict-overflow -fconserve-stack -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(dma_mapping)" -D"KBUILD_MODNAME=KBUILD_STR(dma_mapping)" -c -o arch/arm/mm/dma-mapping.o /home/cjb/git/olpc-kernel/arch/arm/mm/dma-mapping.c /home/cjb/git/olpc-kernel/arch/arm/kernel/entry-armv.S: Assembler messages: /home/cjb/git/olpc-kernel/arch/arm/kernel/entry-armv.S:207: Error: selected processor does not support ARM mode `clrex' CPU_32v5=y adds: arch/arm/Makefile:arch-$(CONFIG_CPU_32v5) :=-D__LINUX_ARM_ARCH__=5 $(call cc-option,-march=armv5te,-march=armv4t) - Chris. -- Chris Ball <[email protected]> <http://printf.net/> One Laptop Per Child _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
