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