[PATCH 0/3] MIPS: pbl: add nmon MIPS nano-monitor

[Antony Pavlov]

nmon is a tiny monitor (<1200 bytes) program
for the MIPS processors.
It can operate with NO working RAM at all!
It uses only the processor registers and NS16550-compatible
UART port for operation, so it can be used for a memory
controller setup code debugging.

With no changes nmon should work on different MIPS
processors as it uses only common MIPS-I instructions.
