2. 编译过程
   

3. 创建文件
   

命令：make -f ./scripts/Makefile.build obj=dts

1. 经过《36.1 dts/Makefile 文件分析》分析可知：

#  dts/Makefile 
targets += dt.dtb
DEVICE_TREE = bcm2837-rpi-3-b
DTB = arch/arm/dts/bcm2837-rpi-3-b.dtb

2. 经过《36.2 创建 $(builtin-target)》 和步骤1的分析可知，依赖$(builtin-target)最终创建规则如下：

# scripts/Makefile.build 
# 输入命令：make -f ./scripts/Makefile.build obj=dts
builtin-target := $(obj)/built-in.o

300 $(obj)/%.o: $(src)/%.S FORCE
301 	$(call if_changed_dep,as_o_S)

336 cmd_link_o_target = $(if $(strip $(obj-y)),\
337 		               rm -f $@; $(AR) cDPrsT $@ $(filter $(obj-y), $^), \
338 		               rm -f $@; $(AR) cDPrsT$(KBUILD_ARFLAGS) $@)
339 
340 $(builtin-target) : $(obj)/dt.dtb.o FORCE
341 	   $(call if_changed,link_o_target)

3. 在《1.1 引用文件》引用的scripts/Makefile.lib中有如下创建规则：

# scripts/Makefile.lib
# make -f ./scripts/Makefile.build obj=dts
311 $(obj)/%.dtb.S: $(obj)/%.dtb
312 	$(call cmd,dt_S_dtb)
331 $(obj)/%.dtb: $(src)/%.dts FORCE
332    $(call if_changed_dep,dtc)

由上可知，并且在scripts/Makefile.build中，300行的 $(src)=$(obj) ，最终创建规则如下所示：

# 输入命令：make -f ./scripts/Makefile.build obj=dts
# scripts/Makefile.build 
builtin-target := $(obj)/built-in.o

1. 8-11行：在《1.2 用规则新建 -include 声明的文件》的include/config/auto.conf中CONFIG_DEFAULT_DEVICE_TREE="bcm2837-rpi-3-b"，所以： DEVICE_TREE = bcm2837-rpi-3-b
2. 13-17行：$(EXT_DTB)未定义为空，所以： DTB = arch/arm/dts/bcm2837-rpi-3-b.dtb
3. 19-21行：由于SPL_NAME = spl，dt-$(SPL_NAME).dtb不存在，所以这里不执行
4. 23-29行：CONFIG_TPL_BUILD未定义为空
5. 46-53行：CONFIG_SPL_BUILD未定义为空
6. 52行：在include/config/auto.conf中CONFIG_OF_EMBED=y
7. 60-61行：这里一般都不会执行
