Since the imx8mm beacon boards and the imx8mm venice board both show
promise, does it make sense to 'imply' the LTO for anything enabling
imx8mm?
Same thing for the various omap3 boards, and potentially the renesas
RZ/G2 boards.  I know Tom went through to remove a bunch of boards
that were never converted to DM.  Most of the boards remaining boards
have minimal board files and most of code is common to other boards in
the same platforms.

I have an l138_lcdk that I can use to test which I expect to be
similar to the da850evm.
