[Qemu-devel] [PULL 30/30] hw/core/generic-loader: Allow PC to be set on command line

[Peter Maydell]

The documentation for the generic loader claims that you can
set the PC for a CPU with an option of the form
  -device loader,cpu-num=0,addr=0x10000004

However if you try this QEMU complains:
  cpu_num must be specified when setting a program counter

This is because we were testing against 0 rather than CPU_NONE.
