At least for Beagle (and I assume it's same for SDP, but don't have one to test with) the problem is that u-boot leaves the USB OTG block in a state that does not idle, and thus prevents CORE from hitting RET. The solution: ensure the USB OTG block is reset. Also in my tree, threre is an usb-otg-reset branch which you can merge with pm-core to test if this helps. Until we have the USB OTG hwmod conversion merged, this temporary hack is needed. After conversion to hwmod, all hwmod will be reset during boot so we are not affected by bootloader (mis)behavior.
