MTK 6752/6732支持6630

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：
