Just to confirm, my problems with mainline were with appended DTB also.
Separate DTB and zImage work fine (at least using u-boot v2013.04.)

That being said, appended DTB should still work, so there's a bug hiding
someplace that needs to be found fixed.

Since we've narrowed down what the problem is, someone can bisect it
now, yeah.

Can you guys update your tests to test appended DTB also?

What is the official position on appending DTBs?

If a platform goes from being able to boot without a DTB to requiring
a DTB, we must continue to support booting on that platform in some
manner otherwise it is a regression.

And no, I don't term upgrading uboot as an acceptable regression fix.
So if appended DTB doesn't work, that needs fixing before the non-DTB
support for a platform is removed, otherwise we _will_ have a regression.
