FLASH结构

mergedir/code.tmp.bin　　压缩未加密文件的FLASH文件

mergedir/sfs/nvm.bin　　   shareData数据文件，未加密、未压缩

数据克隆：DATA/ALL

APP_Clone_Backup_SystemData_To_USBBackup(CV_FM_DATA)

APP_Clone_Backup_FlashData_To_USBBackup(DataType_t DataType)  //BACKUP_ROMBIN_DATA

中间件的读写：　　Cmd_FlashWrite(UINT32 destAddr, UINT32 srcAddr, UINT32 size)

中间件模块读写：　Cmd_FlashModuleUpdate(INT8 * moduleName, INT8 * updateData, UINT32 updateSize)

通过ID寻找地址：  Cmd_GetAddrAndSizeByFlashID(UINT8 flashID, UINT32 *pFlashAddr, UINT32 *pFlashSize)

shareData的读写：tv_SaveFlashSetting()

读写FLASH: spi_write_flash

更新POWER键：update_option_ir_power_key

SFS底层调用：spi_dmawrite(__u32 dest,__u32 src,__u32 size)

信号量的操作：VD_SEM_TAKE/VD_SEM_GIVE

设备读：Cmd_NVMRead(UINT8 eNvmID, UINT8 u8Compress, UINT32 u32Count, UINT8 *pu8Buffer)

设备写：Cmd_NVMWrite(UINT8 eNvmID, UINT8 u8Compress, UINT32 u32Count, UINT8 *pu8Buffer)

组件装载：AL_Setting_Reload(AL_SETTING_HANDLE handle, al_uint8 user_pref_id) //user_pref_id=0xff 装载整个设备到cache

读取默认值到cache：AL_Setting_ReadDefault(AL_SETTING_HANDLE handle,al_uint8 user_pref_id, const al_void *data)

读写内存：AL_Setting_Read()/AL_Setting_Write()

写FLASH：AL_Setting_Store()
