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