[1] and [2] have a jtag adapter on the side, and the adpater can be bought with the device [4]. [3] just needs a micro-usb cable and is "unbrickable" even when replacing u-boot. I have yet to test this. ;-)
I gave that a whirl, by, uh, accident. But I could xmodem send the SPL over again to get it back, and reprogram the u-boot with the proper version again. (Using 'screen' and sx, minicom does not work).
So it does seem "unbrickable".
