We should probably call it -kernel-dtb. If there's some strncmp() from
-kernel interfering, we should fix that instead.

I don't see this variable being used anywhere in this series though.
Would it have been in the missing zynq machine of 7/7?

I'd prefer a different solution. As far as I have understood,
the dtb is only useful with a kernel, so it could be handled
as an optional attribute to the -kernel parameter:

    -kernel IMAGE[,dtb=DTB]

Of course the same applies to -append, but that's a different issue.

Regards,
Stefan
