28486ff301 Remove the _cookie member of the DMA tag; it's not used by anything. (This 
was already done to the i386 port.)

7b37a276e2 Sync w/ i386 port: 
Optimize the ISA DMA map load somewhat; don't traverse the buffer twice.
Instead, just attempt to do a normal load first.  If we exceed the bounce
threshold or the number of segments, then we bounce the transfer.

6ffa35b390 Sync w/ i386 port: 
When loading a DMA map, if the page's physical address exceeds the bounce
threshold, return an error to the caller (the caller will attempt to
bounce the transfer).

910666949f An inability to map a slot's address space may be a normal condition -- 
for instance, on-board video may live here.  Make the complaint about
this a DEBUG rather than a DIAGNOSTIC message.

da2f2cb79f Store the PA of the framebuffer in the softc. This eliminates the need 
for the sc_phys callback; we can just store the PA in the grfbus attach
args, rather than a function pointer, which simplifies the code nicely.

5852faaf84 Device driver for the SMC 83c170 Ethernet PCI Integrated Controller (EPIC/100) 
used in the SMC EtherPower II.

Media control isn't yet supported, due to some MII infrastructure
problems which I hope to address soon.  This isn't a huge deal, since
the PHY defaults to auto-negotiate mode.

Also, the device just programs the multicast hash table to accept all
multicast, to avoid a hardware bug that causes the multicast address
filter to lose in 10Mb/s mode.  This bug will be fixed in a more sane
way once the media control issues are dealt with.

09a9c016e3 Added Manuel Bouyer's recent i386 _bus_dmamap_load_buffer() patch :- 
Add handling of DMA boundary barrier in _bus_dmamap_load_buffer(). This
affects all bus_dmamap_load* functions of bus_dma(9).
While I'm there fix a bug where the dm_segs array could be overflowded by one.
