scw 3f2adcb2b0 Checkpoint of code to add VMEbus slave support using vme_dmamap* and
vme_dmamem*.

This is still a work in progress, but seems to DTRT on mvme167 so far.

TODO:
	. Get VMEbus slave mode going on mvme147. This should be easy.
	. Fix up the A16 slave mappings.
	. Bounce buffer support. (Messy, but pretty much a `must have'.)
	. Figure out how to deal with `location monitor' interrupts
	  within the framework. (Useful for Busnet, among other things.)
	. It would be nice to make use of the VMEchip2's DMA facilities...

scw 9c745dbd5e Merge 'scw_mvme68k_bus_space' branch with the trunk.
These changes add support for:

	o The MI VMEbus framework on both MVME147 and MVME167.
	o Enhancements to the existing MD bus_space(9) implementation.
	o Most of the bus_dma(9) API.
