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