5801c73162 - Remove ixpsip_bs_tag (ixp425_sip_io.c). It just duplicated some of 
the functionality of ixp425_bs_tag.
 - Add missing stream_{read,write}_1 ops to ixp425_bs_tag.
 - Re-work the delay() implementation to use the free-running Time-
   Stamp counter. This removes the need to bootstrap TMR0 early on.

e9cd075343 It makes more sense to map the expansion bus registers in ixpsip 
instead of the pci bridge driver.

3a414f559e Use pmap_enter() instead of pmap_kenter_pa() as the former automatically 
ensures the mapping is cache-inhibited, so we don't have to frob the PTE
directly.

0047ff3f6e Ok, I give up for now. There's no easy/reliable way to deal with 
these spurious interrupts.

ecc5fec473 If no interrupt handler claims to have dealt with a level-triggered 
GPIO interrupt, check the GPIO interrupt status register after clearing
it down to see if the interrupt source has disappeared. If it does,
assume it was a spurious event. Otherwise, panic.

fb2c521159 Make it easier to support different types of IXP425 board: 
- Move board-specific PCI/GPIO initialisation to its rightful place.

 - Handle clearing down latched GPIO interrupts in a board-independent way.

 - Use MI com(4) driver for on-chip UARTs.

 - Misc. tidying up.

Tested on IXDP425.

22c08fe417 PCI-X requires that that devices updated their PCIXSR on every 
config write with the device number specified in AD[15:11].  If
we don't set this field when issuing a Type 0 cycle, each device
could end of thinking it is at device 0, which can cause a number
of problems.  Doing this unconditionally should be OK when only
PCI devices are present.

7dd7f8baa2 Handle 64bit DMA addresses on PCI for platforms that can (currently only 
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

5ae120da7b Introduce a new "type" field in the softc which is used to indicate 
the general UART type.  Currently, we have "normal", "hayesp" and
"pxa2x0" types.  Replace the corresponding hw flags with the new type
values.

 - Add an INTC driver.
 - Add a GPIO driver.
 - Add attach glue for the PXA2x0's "almost" 16550-compatible uarts.
 - Tweak the LCD driver to use the GPIO driver's services for setting
   up GPIO pin function.
