add definitions and code to support use of multiple I/O and _dense_
...
memory regions.

implement bus_mem_subregion() and bus_io_subregion().

add support for mapping multiple memory windows. This is necessary
...
for mapping ISA/EISA 'hole' memory on the AlphaStation 600.

wrap __STRING() in a #define so that its argument, which must be
...
expanded by the preprocessor, will be. Problem pointed out by Matt
Thomas.

c6dd609e7f
gross hack to get around the fact that there are currently devices with
...
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support. As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.

chipset 'bus' functions that seem to be common to all host bus
...
adapters that exist in single-CPU systems. APECS, CIA, and LCA
all use this, but with different #defines.
