[PATCH 0/5][RFC][POWERPC] 8xx: Add support for FSL 8xx and 885add eval board

The following series intended to port the 8xx boards support to arch/powerpc
together with mpc885ads reference board. It features regression-less transaction
(all the peripherials work, namely SMC1,2 UARTs, FEC1,2 or SCC3 Ethernet.

The Documentation stuff definitely needs to be re-synced with this SoC details,
but the entire stuff may be useful as it is now, and I'm expecting some feedback 
meanwhile.
