Newer boards have been used for recent development, but it shouldn't be 
too hard to get other boards to work.  With the device tree, a lot more 
of the hardware description is done in a data structure, rather than 
scattered throughout code.

I'd start by taking one of the existing supported 8xx boards in the 
current tree, and adapting its device tree and platform file to describe 
the BSE-IP, using the old code as a reference.  You may also need 
bootwrapper changes, depending on what firmware you use.

Things have changed enough that I don't recommend trying to directly 
merge the old code into the new kernel.
