As you've noted, flash-kernel has no way of distinguishing which variant to support, though u-boot does. I've sometimes wondered weather u-boot should pass a boot argument for which .dtb to use... To make matters worse, in older versions of the linux kernel, such as the 3.16.x in jessie, imx6q-wandboard.dtb may actually be for wandboard revb variants, not for the revc variants (although I have one of each, both running the same .dtb in jessie without obvious problem, though I don't make use of the wifi or bluetooth on either). When the revc was added, backwards compatibility was broken by renaming the revb .dtb file instead of keeping it and introducing the revc in a new .dtb... kind of hard to fix correctly now... Adding support for flash-kernel to copy multiple, or even optionally all .dtb files could at least work around the issue. live well, vagrant
