分享一下我老师大神的人工智能教程！零基础，通俗易懂！http://blog.csdn.net/jiangjunshow
也欢迎大家转载本篇文章。分享知识，造福人民，实现我们中华民族伟大复兴！
需要两方面处理：
一 根据原理图配置好GPIO
二 修改代码，有如下几只文件需要修改：
1 alps/mediatek/config/{project}/ProjectConfig.mk添加如下option:
CUSTOM_HAL_COMBO=mt6630
CUSTOM_HAL_ANT=mt6630_ant_m1
MTK_COMBO_CORE_DUMP_SUPPORT=no
MTK_COMBO_QUICK_SLEEP_SUPPORT=no
MTK_COMBO_CHIP = MT6630
MTK_WLAN_CHIP=MT6630
MTK_BT_CHIP = MTK_MT6630
MTK_GPS_CHIP = MTK_GPS_MT6630
MTK_FM_CHIP=MT6630_FM
(注意：最好double check原ProjectConfig文件是否已经存在某项option，如果存在且取值一样，则不需要添加；如果只是值不同，则修改为上述值)
2 alps/mediatek/config/{project}/init.project.rc factory_init.project.rc meta_init.project.rc这三只文件
统一作如下2处修改:
service conn_launcher /system/bin/logwrapper /system/bin/6620_launcher -p /system/etc/firmware/
改为：
service 66xx_launcher /system/bin/logwrapper /system/bin/6620_launcher -m 4 -p /system/etc/firmware/
在文件末尾添加：
service autokd /system/bin/autokd
class core
user system
group nvram system
3 alps\mediatek\config\{project}\autoconfig\kconfig\project文件末尾添加：
CONFIG_SDIOAUTOK_SUPPORT=y
4 alps\mediatek\custom\{project}\kernel\core\src\board-custom.h文件作如下3处改动：
//#define CFG_DEV_MSDC3
改为：
#define CFG_DEV_MSDC3
#define CONFIG_MTK_COMBO_SDIO_SLOT (3)
改为：
#define CONFIG_MTK_WCN_CMB_SDIO_SLOT (3)
#undef CONFIG_MTK_COMBO_SDIO_SLOT
改为：
#undef CONFIG_MTK_WCN_CMB_SDIO_SLOT
5 alps\mediatek\custom\{project}\kernel\core\src\board.c文件,因改动内容较多，
最好整个将文件替换为如下内容：

一 根据原理图配置好GPIO
二 修改代码，有如下几只文件需要修改：
1 alps/mediatek/config/{project}/ProjectConfig.mk添加如下option:
CUSTOM_HAL_COMBO=mt6630
CUSTOM_HAL_ANT=mt6630_ant_m1
MTK_COMBO_CORE_DUMP_SUPPORT=no
MTK_COMBO_QUICK_SLEEP_SUPPORT=no
MTK_COMBO_CHIP = MT6630
MTK_WLAN_CHIP=MT6630
MTK_BT_CHIP = MTK_MT6630
MTK_GPS_CHIP = MTK_GPS_MT6630
MTK_FM_CHIP=MT6630_FM
(注意：最好double check原ProjectConfig文件是否已经存在某项option，如果存在且取值一样，则不需要添加；如果只是值不同，则修改为上述值)
2 alps/mediatek/config/{project}/init.project.rc factory_init.project.rc meta_init.project.rc这三只文件
统一作如下2处修改:
service conn_launcher /system/bin/logwrapper /system/bin/6620_launcher -p /system/etc/firmware/
改为：
service 66xx_launcher /system/bin/logwrapper /system/bin/6620_launcher -m 4 -p /system/etc/firmware/
在文件末尾添加：
service autokd /system/bin/autokd
class core
user system
group nvram system
3 alps\mediatek\config\{project}\autoconfig\kconfig\project文件末尾添加：
CONFIG_SDIOAUTOK_SUPPORT=y
4 alps\mediatek\custom\{project}\kernel\core\src\board-custom.h文件作如下3处改动：
//#define CFG_DEV_MSDC3
改为：
#define CFG_DEV_MSDC3
#define CONFIG_MTK_COMBO_SDIO_SLOT (3)
改为：
#define CONFIG_MTK_WCN_CMB_SDIO_SLOT (3)
#undef CONFIG_MTK_COMBO_SDIO_SLOT
改为：
#undef CONFIG_MTK_WCN_CMB_SDIO_SLOT
5 alps\mediatek\custom\{project}\kernel\core\src\board.c文件,因改动内容较多，
最好整个将文件替换为如下内容：
