The problem with that statement, and why I poked rmk the other week to
confirm, and posted a patch to enable appended dtb support in the
omap2plus_defconfig is that Grants statement conflicts with rmk's statement.

Now, my personal preference, with my U-Boot guy hat on, would be to say
that eval boards (those things that come with support and instructions
on un-bricking them, and really have to have bootloader source available
when applicable, or should be thrown back at the vendor, with extreme
prejudice) ought to require passed dtbs even if that means upgrading
bootloader.  Shipping product boards, well, you make do, and that
probably means passing a new bootloader to the locked bootloader to pass
in a separate dtb is going to be left to the folks who think that is
fun.  Everyone else will be happy just booting mainline(ish) kernels
with appended dtb.
