1.配置文件

在out\target\product\msm8909\obj\KERNEL_OBJ\.config中可以看到

# CONFIG_MTD_LPDDR is not set
# CONFIG_MTD_UBI is not set
CONFIG_DTC=y
CONFIG_OF=y

#
# Device Tree and Open Firmware support
#
# CONFIG_PROC_DEVICETREE is not set
# CONFIG_OF_SELFTEST is not set
CONFIG_OF_FLATTREE=y
CONFIG_OF_EARLY_FLATTREE=y
CONFIG_OF_ADDRESS=y
CONFIG_OF_IRQ=y
CONFIG_OF_DEVICE=y
CONFIG_OF_I2C=y
CONFIG_OF_NET=y
CONFIG_OF_MDIO=y
CONFIG_OF_SPMI=y
CONFIG_OF_MTD=y
CONFIG_OF_SLIMBUS=y
CONFIG_OF_BATTERYDATA=y
CONFIG_OF_RESERVED_MEM=y
...

但这个文件是自动生成的，应该主要是由\kernel\arch\arm\configs下的文件汇总的，但是没有找到定义CONFIG_OF=y的源头。
