一、获取Linux默认班级配置文件：
1.1 Linux:
zengjf@desk-ubuntu:~/uboot-fsl_uboot_L4.1.15_from_TP/configs$ make mx6dlsabresd_defconfig V=1
make -f ./scripts/Makefile.build obj=scripts/basic
rm -f .tmp_quiet_recordmcount
make -f ./scripts/Makefile.build obj=scripts/kconfig mx6dlsabresd_defconfig
scripts/kconfig/conf --defconfig=arch/../configs/mx6dlsabresd_defconfig Kconfig
#
# configuration written to .config
#
1.2 Android:
zengjf@desk-ubuntu:~/uboot-fsl_uboot_L4.1.15_from_TP/configs$ make mx6dlsabresdandroid_defconfig V=1
make -f ./scripts/Makefile.build obj=scripts/basic
rm -f .tmp_quiet_recordmcount
make -f ./scripts/Makefile.build obj=scripts/kconfig mx6dlsabresdandroid_defconfig
scripts/kconfig/conf --defconfig=arch/../configs/mx6dlsabresdandroid_defconfig Kconfig
#
# configuration written to .config
#
二、获取班级头文件目标：
2.1 Linux:
zengjf@desk-ubuntu:~/uboot-fsl_uboot_L4.1.15_from_TP/configs$ cat arch/../configs/mx6dlsabresd_defconfig
CONFIG_ARM=y
CONFIG_ARCH_MX6=y
CONFIG_TARGET_MX6SABRESD=y
CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6sabresd/mx6dlsabresd.cfg,MX6DL,SYS_USE_SPINOR"
CONFIG_CMD_GPIO=y
2.2 Android:
zengjf@desk-ubuntu:~/uboot-fsl_uboot_L4.1.15_from_TP/configs$ cat arch/../configs/mx6dlsabresdandroid_defconfig
CONFIG_ARM=y
CONFIG_ARCH_MX6=y
CONFIG_TARGET_MX6SABRESD=y
CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6sabresd/mx6dlsabresd.cfg,MX6DL,SYS_USE_SPINOR,ANDROID_SUPPORT"
CONFIG_CMD_GPIO=y
三、板级头文件：
1. 根据前面的CONFIG_TARGET_MX6SABRESD --> mx6sabresd
2. include/configs/mx6sabresd.h
1. #include "mx6sabre_common.h"
2. #include "mx6sabreandroid_common.h" # 依据CONFIG_ANDROID_SUPPORT宏进行加载
