Emulate a 3A5000 board use the new loongarch instruction. 3A5000 belongs to the Loongson3 series processors. The board consists of a 3A5000 cpu model and the virt bridge. The host 3A5000 board is really complicated and contains many functions.Now for the tcg softmmu mode only part functions are emulated.
