I have just tested on zedboard rev-C I have here
Head u-boot commit commit
commit 2c072c958bb544c72f0e848375803dbd6971f022
Author: Simon Glass <sjg at chromium.org>
Date: Thu Feb 27 13:26:25 2014 -0700
sandbox: config: Enable cros_ec emulation and related items
Enable the Chrome OS EC emulation for sandbox along with LCD, sound
expanded GPIOs and a few other options to make this work correctly.

More things has changed recently.
If you do these changes then non DT configuration is performed.

Then you can use u-boot also for boot.bin (bootgen) generation.
load fsbl as above and then
dow u-boot

Jagan wasn't correct on this one because one of my patch series has changed this.
For static configuration (without OF_CONTROL) are driver statically defined.
For DT configuration is console selection taken from DTS/DTB.

Jagan maybe knows more but I don't think u-boot-dtb.elf is generated.
Just u-boot-dtb.bin is generated which should be copied as data file
in xmd and not sure if binary file can be directly used for bootgen.
Thanks,
