Sure, but it shows there is still interest to that processor. The 885 is
a good recent 8xx.
u-boot is not really something we focus on. We update it once a year, as
far as it can start our Linux box we are happy.
I did't know. Indeed I was not following uboot activity until someone
who knows the level of interest we have in 8xx alerted me yesterday.
It would have been nice if you had notified linuxppc-dev list.

Ok, I'll try and come with a patch to convert 8xx in the coming weeks.
In the mean time please revert the deletion in order to avoid nightmare
conflicts when the converting patch comes.
