[yocto] which is the official(?) OE/YP openbmc layer?

  for curiosity's sake, i spent a few minutes ignoring the apparent
facebook fork and concentrated strictly on the top-level
github/openbmc content, and it seems amazingly convoluted.  starting
here:

  https://github.com/openbmc

i further checked out the next-level openbmc/openbmc git repo and,
holy mackinaw, it contains a ton of layers.

  ignoring all of the symlinked layers for regular OE/YP content
contained therein, one sees, from the top of that clone, all of the
following "layer.conf" files:

$ find . -name layer.conf
./meta-phosphor/conf/layer.conf
./meta-openbmc-machines/meta-x86/meta-mellanox/conf/layer.conf
./meta-openbmc-machines/meta-x86/meta-mellanox/meta-msn/conf/layer.conf
./meta-openbmc-machines/meta-x86/conf/layer.conf
./meta-openbmc-machines/meta-x86/meta-quanta/meta-q71l/conf/layer.conf
./meta-openbmc-machines/meta-x86/meta-quanta/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-rackspace/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-rackspace/meta-barreleye/conf/layer.conf
./meta-openbmc-machines/meta-openpower/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ingrasys/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ingrasys/meta-zaius/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ibm/meta-garrison/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ibm/meta-firestone/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ibm/meta-romulus/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ibm/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ibm/meta-palmetto/conf/layer.conf
./meta-openbmc-machines/meta-openpower/meta-ibm/meta-witherspoon/conf/layer.conf
./meta-openbmc-machines/meta-evb/conf/layer.conf
./meta-openbmc-machines/meta-evb/meta-evb-aspeed/conf/layer.conf
./meta-openbmc-machines/meta-evb/meta-evb-aspeed/meta-evb-ast2500/conf/layer.conf
./meta-openbmc-bsp/meta-aspeed/conf/layer.conf
./meta-openbmc-bsp/meta-aspeed/meta-ast2500/conf/layer.conf
./meta-openbmc-bsp/meta-aspeed/meta-ast2400/conf/layer.conf
$

  not only does that single "git clone" apparently contain 23
individual layers, some of the content represents independent projects
in github. for example:

  openbmc/meta-aspeed <==> openbmc/openbmc/meta-openbmc-bsp/meta-aspeed

same with meta-openpower, possibly others.

  sorry to pollute this ML with questions about a specific layer, i
just figured it would be a piece of cake to take a look at this stuff
for a colleague and it got ugly in a hurry.

  i'll check in with the actual maintainers, but if anyone out there
is doing current work with openbmc, any pointers as to the current
state of that content would be appreciated.
