I've mentioned this a few times in various threads...no need to use
appended DTB on a current U-Boot. Some of us are indeed booting this way
with the DTB properly passed separately from the bootloader and chosen
filled out by the bootloader. And yes, am335x_evm_config applies to all
AM33xx TI EVMs and the BeagleBone board. There's an EEPROM onboard all
that is used to determine what board is present so a single
MLO/u-boot.img can be used.

As Kevin mentioned earlier, this is unfortunately not true for those of us 
with earlier BeagleBoards:

Yes, we spoke about this a bit.

Do you know what the minimum board revision is that you all are 
supporting in U-boot?

It's not so much a revision as it is getting the right contents in the
EEPROM. As it's a community board, it's generally only supported over at
beagleboard at googlegroups.com. Jason Kridner recommends posting support
questions there (like why isn't my A2 supported in U-Boot?). If there
isn't some solution suggested there for updating the A2 I would contact
him directly. I have an A1 Bone here that also doesn't work with
mainline U-Boot even after configuring the EEPROM. You can try this
procedure if you want to write the proper contents in, an A2 may work
but for some reason there's no available history on Bone revisions prior
to A3. I vaguely recall a lot of chatter around the phy and so forth in
the A1 to A2 timeframe so it's entirely possible that your A2 will work
with just the eeprom contents programmed. Without it, it's guaranteed to
fail as the pin muxing is tied to detecting the board this way. Also,
you may need to change <offset>.1 in the below example to <offset>.2 for
your eeprom i/o to work as A2 may require an address length of 2.

Ok, very quick update...no need to mess around with the eeprom. I just
received the official word on what will be supported. Since A2 is
pre-release, simply go to http://beagleboard.org/support/rma and fill
out the form to have it replaced with the current revision (A6).

This applies to *anyone* that received a pre-release A2 board.
