U-Boot doesn't start up after SPL, that is what I see.

I don't have tools or knowledge to investigate this further but here are 
steps to replicate the issue:
1) make mx28evk_config
2) make u-boot.sb
3) set dip switches to usb0 bootmode
4) connect micro-USB cable
5) try to load u-boot.sb using mfgtool (Windows) or imx_hid_recovery 
(Linux) [1]

I tested USB powered mode and 5V wall adapter without difference.
