Well, if you're using u-boot-fslc, you can git blame here http://git.denx.de/?p=u-boot.git;a=summary in order to find *who* I'm not a u-boot community frequent user/member. I mean, I don't follow their changes, so I cannot say why they decided to change so much from one release to another.

Let's wait for someone to comment on this.
