We do this to simplify the 12# bootloader and increase compatibility with OpenFirmware. 13# 14# To this end we need to define BOOTCC, etc, as the tools 15# needed to build the 32 bit image. That's normally the same 16# compiler for the rest of the kernel, with the -m32 flag added. 17# To make it easier to setup a cross compiler, 18# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE 19# in the toplevel makefile. 20 21all: $(obj)/zImage 22 23ifdef CROSS32_COMPILE 24ifdef CONFIG_CC_IS_CLANG 25 BOOTCC := $(CROSS32_COMPILE)clang 26else 27 BOOTCC := $(CROSS32_COMPILE)gcc 28endif 29 BOOTAR := $(CROSS32_COMPILE)ar 30else 31 BOOTCC := $(CC) 32 BOOTAR := $(AR) 33endif 34 35BOOTCFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \ 36 -fno-strict-aliasing -O2 -msoft-float -mno-altivec -mno-vsx \ 37 $(call cc-option,-mno-spe) $(call cc-option,-mspe=no) \ 38 -pipe -fomit-frame-pointer -fno-builtin -fPIC -nostdinc \ 39 $(LINUXINCLUDE) 40 41ifdef CONFIG_PPC64_BOOT_WRAPPER 42BOOTCFLAGS += -m64 43ifdef CONFIG_PPC64_ELF_ABI_V2 44BOOTCFLAGS += $(call cc-option,-mabi=elfv2) 45endif 46else 47BOOTCFLAGS += -m32 48endif 49 50ifdef CONFIG_TARGET_CPU_BOOL 51BOOTCFLAGS += -mcpu=$(CONFIG_TARGET_CPU) 52else ifdef CONFIG_PPC64_BOOT_WRAPPER 53ifdef CONFIG_CPU_LITTLE_ENDIAN 54BOOTCFLAGS += -mcpu=powerpc64le 55else 56BOOTCFLAGS += -mcpu=powerpc64 57endif 58endif 59 60BOOTCFLAGS += -isystem $(shell $(BOOTCC) -print-file-name=include) 61 62ifdef CONFIG_CPU_BIG_ENDIAN 63BOOTCFLAGS += -mbig-endian 64else 65BOOTCFLAGS += -mlittle-endian 66endif 67 68BOOTAFLAGS := -D__ASSEMBLY__ $(BOOTCFLAGS) -nostdinc 69 70BOOTARFLAGS := -crD 71 72BOOTCFLAGS += $(call cc-option,-mno-prefixed) \ 73 $(call cc-option,-mno-pcrel) \ 74 $(call cc-option,-mno-mma) 75 76ifdef CONFIG_CC_IS_CLANG 77BOOTCFLAGS += $(CLANG_FLAGS) 78BOOTAFLAGS += $(CLANG_FLAGS) 79endif 80 81ifdef CONFIG_DEBUG_INFO 82BOOTCFLAGS += -g 83endif 84 85ifeq ($(call cc-option-yn, -fstack-protector),y) 86BOOTCFLAGS += -fno-stack-protector 87endif 88 89BOOTCFLAGS += -include $(srctree)/include/linux/compiler_attributes.h 90BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) 91 92DTC_FLAGS ?= -p 1024 93 94$(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 95$(obj)/ebony.o: BOOTCFLAGS += -mcpu=440 96$(obj)/cuboot-hotfoot.o: BOOTCFLAGS += -mcpu=405 97$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=440 98$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=440 99$(obj)/cuboot-acadia.o: BOOTCFLAGS += -mcpu=405 100$(obj)/treeboot-iss4xx.o: BOOTCFLAGS += -mcpu=405 101$(obj)/treeboot-currituck.o: BOOTCFLAGS += -mcpu=405 102$(obj)/treeboot-akebono.o: BOOTCFLAGS += -mcpu=405 103 104# The pre-boot decompressors pull in a lot of kernel headers and other source 105# files.
