want to clarify (simple) instructions to build for beagleplay

  friend just got a beagleplay, asked me whether there was any
complication in building a simple core-image-minimal with yocto
project ... i did some quick research and, from what i read, it's as
simple as:

  1) check out oe-core, meta-ti and meta-arm layers
  2) add all the relevant layers to bblayers.conf
  3) Set MACHINE = "beagleplay"
  4) "bitbake core-image-minimal"

and one should get an appropriate wic image.

  one question -- are the "master" branches safe for all of the above,
or should one play it safe and check out "wrynose" for all of the
above?

  seems pretty straightforward.
