The Miscellaneous Special Registers Option provides zero to four scratch
registers within the processor readable and writable by RSR, WSR, and
XSR. These registers are privileged. They may be useful for some
application-specific exception and interrupt processing tasks in the
kernel. The MISC registers are undefined after reset.
See ISA, 4.7.3 for details.

Beginning with the RA-2004.1 release, SR access instructions (rsr, wsr,

exception in case the register is not configured for the core.

  target-mips: Fix incorrect code and test for INSV
  xilinx_uartlite: Accept input after rx FIFO pop
  xilinx_uartlite: suppress "cannot receive message"
  xilinx_axienet: Implement R_IS behaviour

The external CPU models were removed on QEMU 1.2, and the support for
the "cpudef" config sections was documented as deprecated, but the
actual removal of the config section was pending.

Now that QEMU 1.3 was released, we can finally kill the support for
cpudef config sections, and support only the built-in CPU models from
target-i386/cpu.c.
