This thread has been moving faster than me. :)

You can use mainline u-boot.  There are some minor missing features, but I
did do some playing with mainline u-boot and xM rev C about a month ago and
it was good.  The version might not be reported properly, but the default
was updated to be if it was an unknown xM revision, it would default to the
latest.  Old u-boot versions had a but where they would revert to a really
old version.  If the default was the latest, there would have been no
breakage as no u-boot dependencies changed between xM rev A/B and xM rev C.
