Yes the code can work one the ML410 as well. The thing is that you
would need a recent reference design from Xilinx. Before Xilinx used a
OPB pci bridge and these days they use a PLB (v46) pci bridge. The old
reference designs use the OPB core. I saw someone using a ML410
reference design which used the PBL pci soft-core and the same memory
addresses were even used as in the ml510 reference design I'm using.
I'm not sure where the guy got the design since the xilinx site only
shows old opb_pci stuff. (though the core is nearly the same) Further
most devices are also at the same locations on the pci bus.

Further the ml410 also offers good old lpt1 and some other things
which aren't on the ml510 but yes the pci code and big parts of the
dts file I wrote can be reused.
