MIPS: Add CPU support for Loongson1B
Loongson 1B is a 32-bit SoC designed by Institute of Computing Technology (ICT) and the Chinese Academy of Sciences (CAS), which implements the MIPS32 release 2 instruction set. [ralf@linux-mips.org: But which is not strictly a MIPS32 compliant device which also is why it identifies itself with the Legacy Vendor ID in the PrID register. When applying the patch I shoveled some code around to keep things in alphabetical order and avoid forward declarations.] Signed-off-by: Kelvin Cheung <keguang.zhang@gmail.com> Cc: To: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Cc: wuzhangjin@gmail.com Cc: zhzhl555@gmail.com Cc: Kelvin Cheung <keguang.zhang@gmail.com> Patchwork: https://patchwork.linux-mips.org/patch/3976/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
