[Qemu-trivial] [PULL 1/7] unicore32: abort when entering "x 0" on the mo

Subject: [Qemu-trivial] [PULL 1/7] unicore32: abort when entering "x 0" on the monitor

From: Eduardo Otubo <address@hidden>

Starting Qemu with "qemu-system-unicore32 -M puv3,accel=qtest -S -nographic"
and entering "x 0 " at the monitor prompt leads to abort():

  $ ./unicore32-softmmu/qemu-system-unicore32 -M puv3,accel=qtest -S -nographic
  QEMU 2.9.90 monitor - type 'help' for more information
  (qemu) x 0
  qemu: fatal: uc32_cpu_get_phys_page_debug not supported yet

  PSR=40000013 -Z-- PRIV
  Aborted (core dumped)

This happens because uc32_cpu_get_phys_page_debug() is not implemented
yet, this is a temporary workaround to avoid the crash.
