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