[PATCH 0/1] hw: Add compat machines for 6.2

[Yanan Wang]

This patch adds 6.2 machine types for arm/i440fx/q35/s390x/spapr,
which is originally from [1]. Here resend it separately and hopefully
it can get into upstream first, so that some other patches currently
on the mail list which depend on 6.2 machine compat stuff can be
rebased on this.

Thanks for resending this; I'm doing an arm pullreq today so I'll
put it in with that.
