From: "Steven J. Hill" <sjhill@mips.com>
This set of patches is to support building a pure microMIPS kernel
image using only instruction from the microMIPS ISA. The result is
a kernel binary reduction of more than 20% and an increase in the
speed of execution due to the smaller and faster instructions.
Steven J. Hill (9):
MIPS: Add microMIPS breakpoints and DSP support.
MIPS: Add support for microMIPS instructions.
MIPS: Add support for microMIPS exception handling.
MIPS: Support microMIPS/MIPS16e handling of delay slots.
MIPS: Support microMIPS/MIPS16e unaligned accesses.
MIPS: Support microMIPS/MIPS16e floating point.
MIPS: Work-around microMIPS GNU assembler bug.
MIPS: Fixup ordering of micro assembler instructions.
MIPS: Add microMIPS configuration option.
