I just noticed you mentioning "gd" here and wanted to point you to a
patch that fixed a gd-related boot issue for me on OMAP3:
[U-Boot] [PATCH 1/3] arm: spl: Fix SPL booting for OMAP3
(sorry, I can't find a link to this patch right now and I'm in a hurry)
Not sure if this has something to do with your problem (I don't have the
time to dig into this mail thread today as I'm leaving right now).
Cheers,
Stefan
