In directory netbsd1:/var/slash-tmp/cvs-serv27094

Modified Files:
      Tag: thorpej-bus-dma
	machdep.c 
Log Message:
Generic i386 implemenatation of the bus dma interface.  These functions
provide support for busses (such as EISA and PCI) which do not have
special needs, but may also be called by busses which do (ISA); These
functions provide the "bottom layer".

NOTE: Not all of the methods defined in the bus dma API have been
implemented (the more exotic ones, such as uio, mbuf, and raw loading,
and the mmap method).  Those will be addressed in the future.

Modified Files:
      Tag: thorpej-bus-dma
	isa_machdep.c isa_machdep.h 
Log Message:
Implement ISA-specific bus dma methods, and provide the bus dma tag
to children via isa_attach_hook().  These bus dma methods are mostly
wrappers around the generic i386 bus dma methods, but include support
for DMA bounce buffers where required.
