[Qemu-devel] [PATCH qemu] qemu-options: Add documentation about PPC64's "-cpu compat" option

[Alexey Kardashevskiy]

Since 8dfa3a5e "target-ppc: Add "compat" CPU option" (which was a part of
client-architecture-support patchset) there is a "compat" option
of "-cpu". However it was not documented at all and this is what this
patch is trying to do.
