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: $(obj)/zImage 22 23compress-$(CONFIG_KERNEL_GZIP) := CONFIG_KERNEL_GZIP 24compress-$(CONFIG_KERNEL_XZ) := CONFIG_KERNEL_XZ 25 26ifdef CROSS32_COMPILE 27 BOOTCC := $(CROSS32_COMPILE)gcc 28 BOOTAR := $(CROSS32_COMPILE)ar 29else 30 BOOTCC := $(CC) 31 BOOTAR := $(AR) 32endif 33 34BOOTCFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \ 35 -fno-strict-aliasing -O2 -msoft-float -mno-altivec -mno-vsx \ 36 -pipe -fomit-frame-pointer -fno-builtin -fPIC -nostdinc \ 37 -D$(compress-y) 38 39ifdef CONFIG_PPC64_BOOT_WRAPPER 40BOOTCFLAGS += -m64 41else 42BOOTCFLAGS += -m32 43endif 44 45BOOTCFLAGS += -isystem $(shell $(BOOTCC) -print-file-name=include) 46 47ifdef CONFIG_CPU_BIG_ENDIAN 48BOOTCFLAGS += -mbig-endian 49else 50BOOTCFLAGS += -mlittle-endian 51BOOTCFLAGS += $(call cc-option,-mabi=elfv2) 52endif 53 54BOOTAFLAGS := -D__ASSEMBLY__ $(BOOTCFLAGS) -traditional -nostdinc 55 56BOOTARFLAGS := -cr$(KBUILD_ARFLAGS) 57 58ifdef CONFIG_CC_IS_CLANG 59BOOTCFLAGS += $(CLANG_FLAGS) 60BOOTAFLAGS += $(CLANG_FLAGS) 61endif 62 63ifdef CONFIG_DEBUG_INFO 64BOOTCFLAGS += -g 65endif 66 67ifeq ($(call cc-option-yn, -fstack-protector),y) 68BOOTCFLAGS += -fno-stack-protector 69endif 70 71BOOTCFLAGS += -I$(objtree)/$(obj) -I$(srctree)/$(obj) 72 73DTC_FLAGS ?= -p 1024 74 75$(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 76$(obj)/ebony.o: BOOTCFLAGS += -mcpu=405 77$(obj)/cuboot-hotfoot.o: BOOTCFLAGS += -mcpu=405 78$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=405 79$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=405 80$(obj)/cuboot-acadia.o: BOOTCFLAGS += -mcpu=405 81$(obj)/treeboot-walnut.o: BOOTCFLAGS += -mcpu=405 82$(obj)/treeboot-iss4xx.o: BOOTCFLAGS += -mcpu=405 83$(obj)/treeboot-currituck.o: BOOTCFLAGS += -mcpu=405 84$(obj)/treeboot-akebono.o: BOOTCFLAGS += -mcpu=405 85$(obj)/virtex405-head.o: BOOTAFLAGS += -mcpu=405 86 87# The pre-boot decompressors pull in a lot of kernel headers and other source 88# files.
