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