Loongson-3A R1/R2/R3 and Loongson-3B R1/R2 use the same package naming in dts, and Loongson-3A R4 will be different. In cpu.h the classic 64bit Loongson processors are called Loongson64C (C for classic, pre Loongson- 3A R4), and the new 64bit Loongson processors are called Loongson64G (G for generic, Loongson-3A R4+). To keep consistency and make extensible, we rename the classic "loongson3" prefix to "loongson64c", and the new prefix for Loongson-3A R4+ will be "loongson64g".
