Strange, I remember the apx4 maintainer didn't work for B/G anymore.

Ah, right. The u-boot.sb is also encrypted with aes-128-cbc with zero key. The 
bootrom on mx23/mx28 has the encryption enabled by default (and it can be fused 
off), with the default key being all zeroes. That's why you see so many 
differences.

No, thank _you_ for putting so much effort into this :)

Yes, I see. We shall eventually rename it to mkimage throughout the code.

How shall we proceed? I see we have three options:
- Post V2 of this patch
- Fix the rest of the files which have this 'UIMAGE' in them and then post V2
- Postpone the fix and then do it globally

I would be in favor of the second option.
