The cv1812h does not have the A53 core as the sg200x does. Maybe we should treat cv1812h as a trim of sg200x, not just a reband. According to this information, I suggest to preserve these code for cv1812h, it can make upstream the new soc eaiser. Also, adding a new compatible is not too hard, and it is necessary if we have new soc. Otherwise, the one with Huashan Pi now may be confused because it have a old version. >Thanks, > >Chen >
