kernel > 3.9, this module it is not compiled.

The chip tundra doesn't support 8 bit data width transfer, it is emulated from wb master, who
provides the select setting for each access. From now on the wb registers can be read/write
only through the vme_wb

generic. Now the the sdb is autogenerated.

I had it in another repo, but now that the things are working better to start compacting the repos

   the VME_Wb interface has an additional register for controlling
   the msi interrupts. The rest of the changes in the VME bus and top
   file are for backwards compatibility. Now the user can synthesize
   for legacy interrupts or msi.

msi_interrupts: add MSI support to VME core. Now the src of an interrupt can be from another module (legacy interrupt) or from the MSI WB bus
