From f93286397ed2a7084efb0362a43ee09f11702349 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Fri, 1 Sep 2006 19:49:50 +0200 Subject: Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory. --- tools/updater/Makefile | 93 ++++++++++++++++++++++++++++++-------------------- 1 file changed, 56 insertions(+), 37 deletions(-) (limited to 'tools/updater') diff --git a/tools/updater/Makefile b/tools/updater/Makefile index 3fa1912..e9684cb 100644 --- a/tools/updater/Makefile +++ b/tools/updater/Makefile @@ -1,5 +1,5 @@ # -# (C) Copyright 2000 +# (C) Copyright 2000-2006 # Wolfgang Denk, DENX Software Engineering, wd@denx.de. # # See file CREDITS for list of people who contributed to this @@ -25,62 +25,81 @@ LOAD_ADDR = 0x40000 include $(TOPDIR)/config.mk -PROG = updater -IMAGE = updater.image -SRC = update.c flash.c flash_hw.c utils.c cmd_flash.c string.c ctype.c dummy.c -ASRC = ppcstring.S -OBJS = $(SRC:.c=.o) $(ASRC:.S=.o) +PROG = $(obj)updater +IMAGE = $(obj)updater.image -LIB = $(TOPDIR)/examples/libstubs.a -LIBAOBJS= -LIBCOBJS= $(TOPDIR)/examples/stubs.o -LIBOBJS = $(LIBAOBJS) $(LIBCOBJS) +COBJS = update.o flash.o flash_hw.o utils.o cmd_flash.o string.o ctype.o dummy.o +COBJS_LINKS = stubs.o +AOBJS = ppcstring.o +AOBJS_LINKS = memio.o + +OBJS := $(addprefix $(obj),$(COBJS) $(COBJS_LINKS) $(AOBJS) $(AOBJS_LINKS)) +SRCS := $(COBJS:.o=.c) $(AOBJS:.o=.S) $(addprefix $(obj), $(COBJS_LINKS:.o:.c) $(AOBJS_LINKS:.o:.S)) CPPFLAGS += -I$(TOPDIR) -I$(TOPDIR)/board/MAI/AmigaOneG3SE CFLAGS += -I$(TOPDIR)/board/MAI/AmigaOneG3SE +AFLAGS += -I$(TOPDIR)/board/MAI/AmigaOneG3SE + +DEPS = $(OBJTREE)/u-boot.bin $(OBJTREE)/tools/mkimage +ifneq ($(DEPS),$(wildcard $(DEPS))) +$(error "updater: Missing required objects, please run regular build first") +endif -all: .depend $(LIB) $(PROG) +all: $(obj).depend $(PROG) $(IMAGE) ######################################################################### -$(LIB): .depend $(LIBOBJS) - $(AR) crv $@ $(LIBOBJS) -%.srec: %.o $(LIB) +$(obj)%.srec: %.o $(LIB) $(LD) -g -Ttext $(LOAD_ADDR) -o $(<:.o=) -e $(<:.o=) $< $(LIB) $(OBJCOPY) -O srec $(<:.o=) $@ -%.o: %.c - $(CC) $(CPPFLAGS) -c $< +$(obj)%.o: %.c + $(CC) $(CFLAGS) -c -o $@ $< + +$(obj)%.o: %.S + $(CC) $(AFLAGS) -c -o $@ $< + +$(obj)memio.o: $(obj)memio.S + $(CC) $(AFLAGS) -c -o $@ $< -%.o: %.S - $(CC) $(CPPFLAGS) -c $< +$(obj)memio.S: + rm -f $(obj)memio.c + ln -s $(SRCTREE)/board/MAI/AmigaOneG3SE/memio.S $(obj)memio.S + +$(obj)stubs.o: $(obj)stubs.c + $(CC) $(CFLAGS) -c -o $@ $< + +$(obj)stubs.c: + rm -f $(obj)stubs.c + ln -s $(SRCTREE)/examples/stubs.c $(obj)stubs.c ######################################################################### -updater: $(OBJS) $(LIB) $(TOPDIR)/board/MAI/AmigaOneG3SE/memio.o - $(LD) -g -Ttext $(LOAD_ADDR) -o updater -e _main $(OBJS) $(LIB) \ - $(TOPDIR)/board/MAI/AmigaOneG3SE/memio.o - $(OBJCOPY) -O binary updater updater.bin +$(obj)updater: $(OBJS) + $(LD) -g -Ttext $(LOAD_ADDR) -o $(obj)updater -e _main $(OBJS) + $(OBJCOPY) -O binary $(obj)updater $(obj)updater.bin -updater.image: updater $(TOPDIR)/u-boot.bin - cat >/tmp/tempimage updater.bin junk $(TOPDIR)/u-boot.bin - $(TOPDIR)/tools/mkimage -A ppc -O u-boot -T standalone -C none -a $(LOAD_ADDR) \ - -e `ppc-elf32-nm updater | grep _main | cut --bytes=0-8` \ - -n "Firmware Updater" -d /tmp/tempimage updater.image +$(obj)updater.image: $(obj)updater $(OBJTREE)/u-boot.bin + cat >/tmp/tempimage $(obj)updater.bin junk $(OBJTREE)/u-boot.bin + $(OBJTREE)/tools/mkimage -A ppc -O u-boot -T standalone -C none -a $(LOAD_ADDR) \ + -e `$(NM) $(obj)updater | grep _main | cut --bytes=0-8` \ + -n "Firmware Updater" -d /tmp/tempimage $(obj)updater.image rm /tmp/tempimage - cp updater.image /tftpboot + cp $(obj)updater.image /tftpboot -updater.image2: updater $(TOPDIR)/u-boot.bin - cat >/tmp/tempimage updater.bin junk ../../create_image/image - $(TOPDIR)/tools/mkimage -A ppc -O u-boot -T standalone -C none -a $(LOAD_ADDR) \ - -e `ppc-elf32-nm updater | grep _main | cut --bytes=0-8` \ - -n "Firmware Updater" -d /tmp/tempimage updater.image +(obj)updater.image2: $(obj)updater $(OBJTREE)/u-boot.bin + cat >/tmp/tempimage $(obj)updater.bin junk ../../create_image/image + $(OBJTREE)/tools/mkimage -A ppc -O u-boot -T standalone -C none -a $(LOAD_ADDR) \ + -e `$(NM) $(obj)updater | grep _main | cut --bytes=0-8` \ + -n "Firmware Updater" -d /tmp/tempimage $(obj)updater.image rm /tmp/tempimage - cp updater.image /tftpboot + cp $(obj)updater.image /tftpboot + +######################################################################### -.depend: Makefile $(SRC) $(ASRC) $(LIBCOBJS:.o=.c) $(LIBAOBJS:.o=.S) - $(CC) -M $(CFLAGS) $(SRC) $(ASRC) $(LIBCOBJS:.o=.c) $(LIBAOBJS:.o=.S) > $@ +# defines $(obj).depend target +include $(SRCTREE)/rules.mk -sinclude .depend +sinclude $(obj).depend ######################################################################### -- cgit v1.1
