Just FYI, meta-boundary isn't strictly necessary for anything unless you
need the QCA wifi driver built into the kernel. You could delete everything
except recipes-kernel/ and conf/ from meta-boundary at pyro, then you'd be
good to go.

Or go without that all together and just use fsl-community-bsp-platform at
rocko branch.
