Guys ... I have two things in my mind. You want to add features, that's fine 
with me. But then, the merge window is closed already, so you have crapload of 
time to work on it. Also, if you won't do it now, noone will ever do it later.

Please, do it now. I don't see it being too much work.

btw. do you remember we've been in such place once already with some other piece 
of u-boot?

Best regards,
