Ha, imx_usb_loader spits out errors if u-boot.bin size goes beyond free OCRAM area. Also, 4kb of u-boot.bin takes not the U-Boot itself, but flash header or something.

Log of errors is here:

Did you see that summary line: <<<76044, 69632 bytes>>> (i.e loaded 69632 of 76044 bytes)? 69632 bytes is 68kb. 68kb = 72kb of free OCRAM area - 4kb of flash header in u-boot.bin.

It's just an observation, nothing more.
