MIPS: Loongson: Add Loongson-3A R2 basic support
Loongson-3 CPU family:
Code-name Brand-name PRId
Loongson-3A R1 Loongson-3A1000 0x6305
Loongson-3A R2 Loongson-3A2000 0x6308
Loongson-3B R1 Loongson-3B1000 0x6306
Loongson-3B R2 Loongson-3B1500 0x6307
Features of R2 revision of Loongson-3A:
- Primary cache includes I-Cache, D-Cache and V-Cache (Victim Cache).
- I-Cache, D-Cache and V-Cache are 16-way set-associative, linesize is
64 bytes.
- 64 entries of VTLB (classic TLB), 1024 entries of FTLB (8-way
set-associative).
- Supports DSP/DSPv2 instructions, UserLocal register and Read-Inhibit/
Execute-Inhibit.
