[RFC v2 1/7] MIPS: Add support for the Lexra LX5280 CPU

2018-10-01 Thread Yasha Cherikovsky
The Lexra LX5280 CPU [1][2] implements the MIPS-I ISA, without unaligned load/store instructions (lwl, lwr, swl, swr). The programming model of this CPU is very similar to the R3000 programming model, with a few differences. The Realtek RTL8186 SoC has this CPU, so this patch is required for futur
