Fair enough, but the way it was done previously was very error-prone if the
base address changed for any reason in the platform code, and you did not
notice it had to be changed in the OHCI driver too, then it simply did not
work. By systems in the field you mean out of tree users? If so, I'd say that
it's up to you to get them maintained or merged.
