what's the bitbake target to create the .dtb file for the BBB?

i've already tested and documented using OE to build a
core-image-minimal for the BBB, but the standard recipe doesn't build
the corresponding device tree .dtb file, so i did a quick google and
came up with this:


"ti-tisdk-makefile: Add build target for linux DTB files"

  am i missing something, or does one need to use the meta-ti layer
for a dtb recipe? just want to know if there's a simple answer before
i go chasing down that layer. thanks.
