Could we fail with an error that tells the user they must use the -E option for dtbs? Or at least emitting a warning would be better than nothing. Not for this patch but for broader discussion, it sounds like a `/align/ 8` could be useful in the devicetree syntax similar to how we have `/bits/ 8|16|32|64` already. This could (eventually) solve the "nothing we can do for embedded data" problem.
