Thanks for the reply, however discouraging!

Currently, I’m running Wheezy on the Base and its sister Ultimate.
I haven’t tried Jessie since the formal release, but I will do that and report 
back soon.  I gather from what you say about DTB that that transition does not 
depend on U-Boot?  So I should be able to upgrade to and beyond Jessie without 
problems?

The problem I’m having with Wheezy that makes me think it would be interesting 
to try a later U-Boot is that the original Marvell U-Boot (from 2009) is balky 
when booting from USB hard disks and doesn’t support booting from SD at all.  
If I could boot from SD, I would put /boot there and everything else on the USB 
disk.  As it is, whenever I need to reboot the machine (I’m using it for 
experimentation, so that happens fairly often.) I need to log in to the serial 
console so I can watch and restart if booting from the hard drive fails.  
(Sometimes it fails in a way that requires actual physically re-setting the 
Base or even power-cycling it, but that’s a different story.)

Can you tell me what the most recent U-Boot version is that actually does 
support the OpenRD Base?  If there is such a thing, do you have a suggested 
procedure for doing the upgrade?

Yes, I noticed.  The web site “openrd.org” now belongs to the Open Road 
Motorcycle Club.  Maybe it’s time to move on… The Cubox devices look 
interesting!
