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 -pipe -fomit-frame-pointer -fno-builtin -fPIC -nostdinc \ 38 $(LINUXINCLUDE) 39 40ifdef CONFIG_PPC64_BOOT_WRAPPER 41ifdef CONFIG_CPU_LITTLE_ENDIAN 42BOOTCFLAGS += -m64 -mcpu=powerpc64le 43else 44BOOTCFLAGS += -m64 -mcpu=powerpc64 45endif 46else 47BOOTCFLAGS += -m32 -mcpu=powerpc 48endif 49 50BOOTCFLAGS += -isystem $(shell $(BOOTCC) -print-file-name=include) 51 52ifdef CONFIG_CPU_BIG_ENDIAN 53BOOTCFLAGS += -mbig-endian 54else 55BOOTCFLAGS += -mlittle-endian 56endif 57ifdef CONFIG_PPC64_ELF_ABI_V2 58BOOTCFLAGS += $(call cc-option,-mabi=elfv2) 59endif 60 61BOOTAFLAGS := -D__ASSEMBLY__ $(BOOTCFLAGS) -nostdinc 62 63BOOTARFLAGS := -crD 64 65ifdef CONFIG_CC_IS_CLANG 66BOOTCFLAGS += $(CLANG_FLAGS) 67BOOTAFLAGS += $(CLANG_FLAGS) 68endif 69 70ifdef CONFIG_DEBUG_INFO 71BOOTCFLAGS += -g 72endif 73 74ifeq ($(call cc-option-yn, -fstack-protector),y) 75BOOTCFLAGS += -fno-stack-protector 76endif 77 78BOOTCFLAGS += -include $(srctree)/include/linux/compiler_attributes.h 79BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) 80 81DTC_FLAGS ?= -p 1024 82 83$(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 84$(obj)/ebony.o: BOOTCFLAGS += -mcpu=440 85$(obj)/cuboot-hotfoot.o: BOOTCFLAGS += -mcpu=405 86$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=440 87$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=440 88$(obj)/cuboot-acadia.o: BOOTCFLAGS += -mcpu=405 89$(obj)/treeboot-iss4xx.o: BOOTCFLAGS += -mcpu=405 90$(obj)/treeboot-currituck.o: BOOTCFLAGS += -mcpu=405 91$(obj)/treeboot-akebono.o: BOOTCFLAGS += -mcpu=405 92 93# The pre-boot decompressors pull in a lot of kernel headers and other source 94# files.
