As you know, we're loading the kernel using a boot script,
with various flavors for differing locations and environments,
so we've found it easier to pass environment variables for
board and CPU type to the boot script.
	https://github.com/boundarydevices/u-boot-imx6/commit/4a4fc304e4fe63cde7b3201f0daab5b1856870e4

This allows the boot script to produce the DTB name as shown
here:
	https://github.com/boundarydevices/u-boot-imx6/blob/staging/board/boundary/nitrogen6x/6x_bootscript.txt#L72

If/when you move to a single binary for DQ/DL, you won't have
a separate choice as shown above.

Let me know your thoughts on this.

We didn't generate a proper patch for lack of time, but I
think that the small addition of code has merit. We also
may want to discuss the specifics in more detail.

Regards,


Eric
