So, the defconfig change here is wrong, CMD_PART isn't being implied
otherwise, and this board is part of a number of boards that had
EFI_LOADER before, but not DOS_PARTITION, and so do grow, but in a
valid/expected way.  There are also a number of boards that don't have
any partition type support set, but that too I think ends up being
correct.  The whole before/after is at
