Subject: [PATCH v4 0/7] Add basic support for Loongson-2K1000

These patches support single-core DTS boot to the serial port login
interface, which can be operated using conventional commands.

I have successfully tested it on the Loongson 2K1000 machine.
pmon: http://cgit.loongnix.org/cgit/pmon-loongson3/

Note:
After the basic support is merged, 
I will submit SMP and other peripheral support in the future.
