Ahh yeah, I had to change that too.  I have a bunch of little changes
to the 5282 code.  Unfortunately a lot of it was done quickly and
needs to be cleaned up before I can submit a patch.  (I did submit a
couple smaller ones at some point, though).  If you search the mailing
list archives for 'fec structure errors?' (which probably would have
been a good idea from the start) you'll see a post from me with a url
to a u-boot tree with my 5282 changes.  NGZ may have also posted his
5282 changes at some point, I can't remember.
