Stefan Eßer 8673e05a9a Completely new PCI code: 
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

David Greenman cb09d35cb0 Added a new field to the pci_device struct called pd_shutdown to specify 
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.

Stefan Eßer a2564a2e9c Disable vga_attach() code, as it always should have been. 1995-03-02 23:29:44 +00:00
Stefan Eßer c79b89e28f Add code to deal with PCI-PCI bridge chips, especially the DEC 21050. 
Try to deduce maximum number of PCI buses in system (working around
chip set bugs).
Better check for devices at multiple addresses (aliases).

Garrett Wollman 522bab9535 Make capitalization consistent with other devices registered in 
the database.  Also, distinguish between VGA-like display devices
and everything else.

David Greenman 6398cf3113 Reapplied all of Stefan's changes. What a mess - the files were modified 
and moved at the same time. This made it *very* difficult to fix the
revision log lossage that happend when the files were moved. SIGH.

Poul-Henning Kamp 161e7c8d87 #ifdef'ed the verbose probe messages. Only until I find a good way of 
making it run-time selectable, then it will be back (at will).
