1) Firstly the cal.Data in flash is downloaded to target RAM @ 0xC0000 2) Followed by first time otp.bin downloaded and execution parameter as \"0x8000\

先从os\\linux\\src目录开始加载，在完成offload加载后再加载qca_da中的内容

统一先加载umac.ko，offload driver是umac的一部分，将先probe offload device。但在qcawifi.sh中，对同时存在direct attach的设备（ap135/ap147/ap151/ap152），会设置wifi_start_idx=1，保证让AHB总线上的射频始终是wifi0
