I doubt this is related to the bootloader. I have the suspicion that is 
actually
a bug in linux but only triggered depending on whether the ROMcode setup
the USB OTG or not. Here is some data to backup my statement:

Linux booting without USB_OTG error trap
md 480022F0 1
480022f0: 0000032f                               /...
md 48002580 1
48002580: 0f00b7a2                               ....

bit USBOTG_PHY_RESET is 0 -> out of reset


USB_OTG sees memory hole
md 480022F0 1
480022f0: 0000030f    ....
md 48002580 1
48002580: 0f00c71e    ....

USBOTG_PHY_RESET is 1 -> still in reset when booting linux.

Does that match with how your am3517 boards boot?

Jeroen
