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?
Regards,
Jeroen
