HPDI register mapping

[Peter Carrigan <petec@acres.com.au>]

Hi all,

I'm working on a system using a PMC HPDI (parallel) card on a MVME2300 board.  I
have successfully found the PCI configuration registers at address 0x80008800,
and the vendor/ device ID etc are correct.  Three base address registers are
implemented (BAR0 - BAR2) and I have written appropriate addresses to these to
try to map the registers to CPU address space.  My problem is that when I try to
access these mapped addresses, all the BAR's seem to point to the same data (I
think this is not supposed to happen but I'm not sure).  Also the data at these
addresses does not seem correct according to the start up default values for the
registers I'm trying to access. Any ideas anyone?

Thanks.

Pete.
