Hi Jason,

If the boards are reasonably similar, the way to go using the device tree
is to have separate dts files but share a single board file that uses the
device tree to figure out the differences.

For the on-chip components, you can even share most of the device tree
contents with an include directive.

In the actual board file, do not list any platform devices, but make
sure that the contents of the device tree file describe the devices
completely. Try to avoid any dependencies on the specific board name
(other than the initial match entry) but instead describe the
differences accurately.
