Ok, so I see you ignore my comments on not using the ATAG_REVISION tag
for passing clock frequncies which is fair enough if nobody else
complains.  

But then please _at least_ document this in the README and not only in
the git diff files.  This is still the most obscure aspects of the
change for me and should be prominent in the documentation.

Cheers
