  Log Message:
  -----------
  nios2: Add disas entries

Add nios2 disassembler support. This patch is composed from binutils files
from commit "Opcodes and assembler support for Nios II R2". The files from
binutils used in this patch are:

    include/opcode/nios2.h
    include/opcode/nios2r1.h
    include/opcode/nios2r2.h
    opcodes/nios2-opc.c
    opcodes/nios2-dis.c

Checkpatch says total: 114 errors, 0 warnings, 3609 lines checked , which
is caused by a different coding style in those files. These warnings and
errors are not addressed To let these files be easily synchronized between
binutils and qemu.

  nios2: Add Altera 10M50 GHRD emulation

Add the Altera 10M50 Nios2 GHRD model. This allows emulating the
10M50 development kit with the Nios2 GHRD loaded in the FPGA. It
is possible to boot Linux kernel and run userspace, thus far only
from initrd as storage support is not yet implemented.
