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 42ifdef CONFIG_CPU_LITTLE_ENDIAN 43BOOTCFLAGS += -m64 -mcpu=powerpc64le 44else 45BOOTCFLAGS += -m64 -mcpu=powerpc64 46endif 47else 48BOOTCFLAGS += -m32 -mcpu=powerpc 49endif 50 51BOOTCFLAGS += -isystem $(shell $(BOOTCC) -print-file-name=include) 52 53ifdef CONFIG_CPU_BIG_ENDIAN 54BOOTCFLAGS += -mbig-endian 55else 56BOOTCFLAGS += -mlittle-endian 57endif 58ifdef CONFIG_PPC64_ELF_ABI_V2 59BOOTCFLAGS += $(call cc-option,-mabi=elfv2) 60endif 61 62BOOTAFLAGS := -D__ASSEMBLY__ $(BOOTCFLAGS) -nostdinc 63 64BOOTARFLAGS := -crD 65 66ifdef CONFIG_CC_IS_CLANG 67BOOTCFLAGS += $(CLANG_FLAGS) 68BOOTAFLAGS += $(CLANG_FLAGS) 69endif 70 71ifdef CONFIG_DEBUG_INFO 72BOOTCFLAGS += -g 73endif 74 75ifeq ($(call cc-option-yn, -fstack-protector),y) 76BOOTCFLAGS += -fno-stack-protector 77endif 78 79BOOTCFLAGS += -include $(srctree)/include/linux/compiler_attributes.h 80BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) 81 82DTC_FLAGS ?= -p 1024 83 84$(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 85$(obj)/ebony.o: BOOTCFLAGS += -mcpu=440 86$(obj)/cuboot-hotfoot.o: BOOTCFLAGS += -mcpu=405 87$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=440 88$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=440 89$(obj)/cuboot-acadia.o: BOOTCFLAGS += -mcpu=405 90$(obj)/treeboot-iss4xx.o: BOOTCFLAGS += -mcpu=405 91$(obj)/treeboot-currituck.o: BOOTCFLAGS += -mcpu=405 92$(obj)/treeboot-akebono.o: BOOTCFLAGS += -mcpu=405 93 94# The pre-boot decompressors pull in a lot of kernel headers and other source 95# files.
