why does meta-intel crownbay-noemgd.conf not require "meta-intel"?

why does meta-intel crownbay-noemgd.conf not require "meta-intel"?

[Robert P. J. Day]

  perusing sample machine conf files and BSP definitions, looking for
nice examples to use in a class in a couple weeks, and i noticed the
following oddity under meta-intel/meta-crownbay.

  while crownbay.conf contains:

require conf/machine/include/tune-atom.inc
require conf/machine/include/ia32-base.inc
require conf/machine/include/meta-intel.inc
require conf/machine/include/meta-intel-emgd.inc

  crownbay-noemgd.conf contains only:

require conf/machine/include/tune-atom.inc
require conf/machine/include/ia32-base.inc

  i would have thought the latter would still need to require
"meta-intel.inc" for consistency.

  i'm sure if i poked around for a few seconds, it would make sense
but, just from a visual point of view -- if someone is reading the
files trying to understand how to define a BSP -- it looks confusing,
no?

Not really - meta-intel is itself a separate layer, and crownbay-noemgd
doesn't need anything from it, so doesn't need the includes for it.

crownbay.conf does need at least emgd and related packages from
meta-intel so includes meta-intel.inc and meta-intel-emgd.inc.
