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 35BOOTCPPFLAGS := -nostdinc $(LINUXINCLUDE) 36BOOTCPPFLAGS += -isystem $(shell $(BOOTCC) -print-file-name=include) 37 38BOOTCFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \ 39 -fno-strict-aliasing -O2 -msoft-float -mno-altivec -mno-vsx \ 40 $(call cc-option,-mno-spe) $(call cc-option,-mspe=no) \ 41 -pipe -fomit-frame-pointer -fno-builtin -fPIC 42 43ifdef CONFIG_PPC64_BOOT_WRAPPER 44BOOTTARGETFLAGS += -m64 45BOOTTARGETFLAGS += -mabi=elfv2 46ifdef CONFIG_PPC64_ELF_ABI_V2 47BOOTTARGETFLAGS += $(call cc-option,-mabi=elfv2) 48endif 49else 50BOOTTARGETFLAGS := -m32 51endif 52 53ifdef CONFIG_TARGET_CPU_BOOL 54BOOTTARGETFLAGS += -mcpu=$(CONFIG_TARGET_CPU) 55else ifdef CONFIG_PPC64_BOOT_WRAPPER 56ifdef CONFIG_CPU_LITTLE_ENDIAN 57BOOTTARGETFLAGS += -mcpu=powerpc64le 58else 59BOOTTARGETFLAGS += -mcpu=powerpc64 60endif 61endif 62 63$(obj)/4xx.o: BOOTTARGETFLAGS += -mcpu=405 64$(obj)/ebony.o: BOOTTARGETFLAGS += -mcpu=440 65$(obj)/cuboot-hotfoot.o: BOOTTARGETFLAGS += -mcpu=405 66$(obj)/cuboot-taishan.o: BOOTTARGETFLAGS += -mcpu=440 67$(obj)/cuboot-katmai.o: BOOTTARGETFLAGS += -mcpu=440 68$(obj)/cuboot-acadia.o: BOOTTARGETFLAGS += -mcpu=405 69$(obj)/treeboot-iss4xx.o: BOOTTARGETFLAGS += -mcpu=405 70$(obj)/treeboot-currituck.o: BOOTTARGETFLAGS += -mcpu=405 71$(obj)/treeboot-akebono.o: BOOTTARGETFLAGS += -mcpu=405 72 73ifdef CONFIG_CPU_BIG_ENDIAN 74BOOTTARGETFLAGS += -mbig-endian 75else 76BOOTTARGETFLAGS += -mlittle-endian 77endif 78 79BOOTAFLAGS := -D__ASSEMBLY__ $(BOOTTARGETFLAGS) $(BOOTCFLAGS) 80 81BOOTARFLAGS := -crD 82 83BOOTCFLAGS += $(call cc-option,-mno-prefixed) \ 84 $(call cc-option,-mno-pcrel) \ 85 $(call cc-option,-mno-mma) 86 87BOOTCFLAGS += $(BOOTTARGETFLAGS) 88 89ifdef CONFIG_CC_IS_CLANG 90BOOTCFLAGS += $(CLANG_FLAGS) 91BOOTAFLAGS += $(CLANG_FLAGS) 92endif 93 94ifdef CONFIG_DEBUG_INFO 95BOOTCFLAGS += -g 96endif 97 98ifeq ($(call cc-option-yn, -fstack-protector),y) 99BOOTCFLAGS += -fno-stack-protector 100endif 101 102BOOTCFLAGS += -include $(srctree)/include/linux/compiler_attributes.h 103BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) 104 105DTC_FLAGS ?= -p 1024 106 107# The pre-boot decompressors pull in a lot of kernel headers and other source 108# files.
