I found here a couple of old uEVMs (the old 750-2617 board
type with OMAP5432 ES1.0 and the old DDR3 power scheme).
One was HS, so of no use directly (no time to play with
image signing). On the GP, I get the following:

my SOM5_EVB board:

I guess something at very low level mem init does not match the 5432 ES1.0
or the DDRs. So unfortunately I can't get to U-Boot and test USB.
Also please notice that the SPL now seems to be executed twice (on both
boards). This was not the case until recently, at least with the mainline.
Anything to do with all those relocation discussions/patches?
Best regards,
Lubo
