# Makefile for making ELF bootable images for booting on CHRP # using Open Firmware. # # Geert Uytterhoeven September 1997 # # Based on coffboot by Paul Mackerras # Simplified for ppc64 by Todd Inglett # # NOTE: this code is built for 32 bit in ELF32 format even though # it packages a 64 bit kernel. We do this to simplify the # bootloader and increase compatibility with OpenFirmware. # # To this end we need to define BOOTCC, etc, as the tools # needed to build the 32 bit image. That's normally the same # compiler for the rest of the kernel, with the -m32 flag added. # To make it easier to setup a cross compiler, # CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE # in the toplevel makefile. all: $(obj)/zImage BOOTCFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \ -fno-strict-aliasing -Os -msoft-float -pipe \ -fomit-frame-pointer -fno-builtin -fPIC -nostdinc \ -isystem $(shell $(CROSS32CC) -print-file-name=include) BOOTAFLAGS := -D__ASSEMBLY__ $(BOOTCFLAGS) -traditional -nostdinc ifdef CONFIG_DEBUG_INFO BOOTCFLAGS += -g endif ifeq ($(call cc-option-yn, -fstack-protector),y) BOOTCFLAGS += -fno-stack-protector endif BOOTCFLAGS += -I$(obj) -I$(srctree)/$(obj) -I$(srctree)/$(src)/libfdt $(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 $(obj)/ebony.o: BOOTCFLAGS += -mcpu=405 $(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=405 $(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=405 $(obj)/treeboot-walnut.o: BOOTCFLAGS += -mcpu=405 $(obj)/virtex405-head.o: BOOTAFLAGS += -mcpu=405 zlib := inffast.c inflate.c inftrees.c zlibheader := inffast.h inffixed.h inflate.h inftrees.h infutil.h zliblinuxheader := zlib.h zconf.h zutil.h $(addprefix $(obj)/,$(zlib) gunzip_util.o main.o): \ $(addprefix $(obj)/,$(zliblinuxheader)) $(addprefix $(obj)/,$(zlibheader)) src-libfdt := fdt.c fdt_ro.c fdt_wip.c fdt_sw.c fdt_rw.c fdt_strerror.c src-wlib := string.S crt0.S crtsavres.S stdio.c main.c \ $(addprefix libfdt/,$(src-libfdt)) libfdt-wrapper.c \ ns16550.c serial.c simple_alloc.c div64.S util.S \ gunzip_util.c elf_util.c $(zlib) devtree.c oflib.c ofconsole.c \ 4xx.c ebony.c mv64x60.c mpsc.c mv64x60_i2c.c cuboot.c bamboo.c \ cpm-serial.c stdlib.c mpc52xx-psc.c planetcore.c uartlite.c \ fsl-soc.c mpc8xx.c pq2.c src-plat := of.c cuboot-52xx.c cuboot-824x.c cuboot-83xx.c cuboot-85xx.c holly.c \ cuboot-ebony.c treeboot-ebony.c prpmc2800.c \ ps3-head.S ps3-hvcall.S ps3.c treeboot-bamboo.c cuboot-8xx.c \ cuboot-pq2.c cuboot-sequoia.c treeboot-walnut.c \ cuboot-bamboo.c cuboot-mpc7448hpc2.c cuboot-taishan.c \ fixed-head.S ep88xc.c ep405.c \ cuboot-katmai.c cuboot-rainier.c redboot-8xx.c ep8248e.c \ cuboot-warp.c cuboot-85xx-cpm2.c cuboot-yosemite.c simpleboot.c \ virtex405-head.S src-boot := $(src-wlib) $(src-plat) empty.c src-boot := $(addprefix $(obj)/, $(src-boot)) obj-boot := $(addsuffix .o, $(basename $(src-boot))) obj-wlib := $(addsuffix .o, $(basename $(addprefix $(obj)/, $(src-wlib)))) obj-plat := $(addsuffix .o, $(basename $(addprefix $(obj)/, $(src-plat)))) quiet_cmd_copy_zlib = COPY $@ cmd_copy_zlib = sed "s@__used@@;s@<linux/\([^>]*\).*@\"\1\"@" $< > $@ quiet_cmd_copy_zlibheader = COPY $@ cmd_copy_zlibheader = sed "s@<linux/\([^>]*\).*@\"\1\"@" $< > $@ # stddef.h for NULL quiet_cmd_copy_zliblinuxheader = COPY $@ cmd_copy_zliblinuxheader = sed "s@<linux/string.h>@\"string.h\"@;s@<linux/kernel.h>@<stddef.h>@;s@<linux/\([^>]*\).*@\"\1\"@" $< > $@ $(addprefix $(obj)/,$(zlib)): $(obj)/%: $(srctree)/lib/zlib_inflate/% $(call cmd,copy_zlib) $(addprefix $(obj)/,$(zlibheader)): $(obj)/%: $(srctree)/lib/zlib_inflate/% $(call cmd,copy_zlibheader) $(addprefix $(obj)/,$(zliblinuxheader)): $(obj)/%: $(srctree)/include/linux/% $(call cmd,copy_zliblinuxheader) $(obj)/empty.c: @touch $@ $(obj)/zImage.lds $(obj)/zImage.coff.lds $(obj)/zImage.ps3.lds: $(obj)/%: $(srctree)/$(src)/%.S @cp $< $@ clean-files := $(zlib) $(zlibheader) $(zliblinuxheader) \ empty.c zImage.coff.lds zImage.ps3.lds zImage.lds quiet_cmd_bootcc = BOOTCC $@ cmd_bootcc = $(CROSS32CC) -Wp,-MD,$(depfile) $(BOOTCFLAGS) -c -o $@ $< quiet_cmd_bootas = BOOTAS $@ cmd_bootas = $(CROSS32CC) -Wp,-MD,$(depfile) $(BOOTAFLAGS) -c -o $@ $< quiet_cmd_bootar = BOOTAR $@ cmd_bootar = $(CROSS32AR) -cr $@.$$$$ $(filter-out FORCE,$^);
