I am trying to write a board support package for the adzs-sc589-ezlite board
from Analog Devices, because AD only supplies a buildroot package, and I would
prefer to use yocto.
AD's buildroot produces a uImage kernel with dtb that is served to the board
using tftp. The root file system is served to the board by nfs.
I've begun working on my own bsp for this board. I have successfully booted and
interacted with the board using buildroot's kernel and dtb combined with
yocto's root filesystem.
I'd now like to replace the buildroot kernel and dtb file with ones generated
by yocto.
My bsp layer is called meta-adzs-sc589-ezlite.
The meta-adzs-sc589-ezlite/conf/machine/adzs-sc589-ezlite.conf contains:
#@TYPE: Machine

What is the common practice for adding .dts/.dtsi files to a bsp in order to
generate a .dtb file during the build?
