Yes, I wasn't clear, sorry for the confusion.  Just this part of the
series should be replaced with making CMD_PART depend on PARTITIONS and
if there really is a use case for 'part' without PARTITION support
(rather than it being an unintentionally enabled feature) we can deal
with it then.  The rest of the series looks good to me and I'll let
Heinrich comment on the EFI specific parts.
