MTK 6752/6732支持6630

需要两方面处理：
1 根据原理图配置好GPIO
2 修改代码，有以下几只文件需要修改：
1 alps/mediatek/config/{project}/ProjectConfig.mk添加以下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文件是不是已存在某项option，如果存在且取值1样，则不需要添加；如果只是值不同，则修改成上述值)
2 alps/mediatek/config/{project}/init.project.rc factory_init.project.rc meta_init.project.rc这3只文件
统1作以下2处修改:
service conn_launcher /system/bin/logwrapper /system/bin/6620_launcher -p /system/etc/firmware/
改成：
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 alpsmediatekconfig{project}autoconfigkconfigproject文件末尾添加：
CONFIG_SDIOAUTOK_SUPPORT=y
4 alpsmediatekcustom{project}kernelcoresrcoard-custom.h文件作以下3处改动：
//#define CFG_DEV_MSDC3
改成：
#define CFG_DEV_MSDC3
#define CONFIG_MTK_COMBO_SDIO_SLOT (3)
改成：
#define CONFIG_MTK_WCN_CMB_SDIO_SLOT (3)
#undef CONFIG_MTK_COMBO_SDIO_SLOT
改成：
#undef CONFIG_MTK_WCN_CMB_SDIO_SLOT
5 alpsmediatekcustom{project}kernelcoresrcoard.c文件,因改动内容较多，
最好全部将文件替换为以下内容：

1 根据原理图配置好GPIO
2 修改代码，有以下几只文件需要修改：
1 alps/mediatek/config/{project}/ProjectConfig.mk添加以下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文件是不是已存在某项option，如果存在且取值1样，则不需要添加；如果只是值不同，则修改成上述值)
2 alps/mediatek/config/{project}/init.project.rc factory_init.project.rc meta_init.project.rc这3只文件
统1作以下2处修改:
service conn_launcher /system/bin/logwrapper /system/bin/6620_launcher -p /system/etc/firmware/
改成：
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 alpsmediatekconfig{project}autoconfigkconfigproject文件末尾添加：
CONFIG_SDIOAUTOK_SUPPORT=y
4 alpsmediatekcustom{project}kernelcoresrcoard-custom.h文件作以下3处改动：
//#define CFG_DEV_MSDC3
改成：
#define CFG_DEV_MSDC3
#define CONFIG_MTK_COMBO_SDIO_SLOT (3)
改成：
#define CONFIG_MTK_WCN_CMB_SDIO_SLOT (3)
#undef CONFIG_MTK_COMBO_SDIO_SLOT
改成：
#undef CONFIG_MTK_WCN_CMB_SDIO_SLOT
5 alpsmediatekcustom{project}kernelcoresrcoard.c文件,因改动内容较多，
最好全部将文件替换为以下内容：
