trivial notes:
Try breaking up the patches you send into more discrete chucks that do just one thing, not mostly one thing and some other things.

It may be better to use a temporary for brd like:
struct dgnc_board *bd = dgnc_Board[brd];
as is done a few other places.

so this becomes di.info->physsize = bd->membase - bd->membase_end;
though I wonder if this is a defect and size should be bd->membase_end - bd->membase + 1
It doesn't need a cast as membase and membase_end are ulong already.
It also seems this physsize variable isn't used.

That's less attractive then what's already there. The generic kernel form for an array declaration would be:
static uint dgnc_offset_table[8] = { 0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80 };
This also would be better as static const.
I stopped reading here.
