Two releases. Deprecated in January: f59fb1889f48 ("hw/i386/pc_piix:
Mark the machine types from version 1.4 to 1.7 as deprecated"), so 7.0
and 7.1, in the 7.2 devel cycle they can be removed. Plus a bunch of
followup cleanups like this patch. I think we can also drop the 128k
seabios images then.
take care,
Gerd
