Support for Marvell Discovery II MV6436x System Controller?

[palle <palle%lyckegaard.dk@localhost>]

As part of an effort to get NetBSD running on the Pegasos platform using 
non-OpenFirmware drivers, I am investigating the MV6436x System 
Controller. 
Apparently there is currently no support for MV6436x 
(http://www.marvell.org/products/communication/discoveryII/MV64360.jsp) in 
NetBSD-current.

There is some code suporting the MV64260 (gt driver) in 
sys/dev/marvell/... and sys/arch/evbppc/ev64260...
Does anyone know the state/quality of the MV64260 code? Would it be a good 
starting point for extending the gt driver with support for the MV6436x.

Any docs available for the MV6436x somewhere?
