The SoCs mt8195 and mt8395 are designed for different market application 
and physical characteristics, using different efuse values for 
distinction. The booting flow and configurations are controllered by the 
boot loaders, firmware, and TF-A. Therefore, the part numbers and 
procurement channels are different. The detail information of these 
efuse values is proprietary, so I cant disclose it futher. Hence the 
most of peripheral drivers and base address are almost the same.
