2007-01-30 Till Straumann <strauman@slac.stanford.edu>

	* vmeUniverse/README.porting, vmeUniverse/README.universe:
	updated, added more information for BSP implementors.

	* vmeUniverse/VMEDMA.h (added): VME DMA API definition.

	* vmeUniverse/bspVmeDmaList.h (added), vmeUniverse/bspVmeDmaListP.h (added),
	* vmeUniverse/bspVmeDmaList.c (added):
	Driver-independent code for linked-list DMA (public + private headers,
	implementation).

	* vmeUniverse/vmeUniverseDMA.h (added), vmeUniverse/vmeTsi148DMA.h (added):
	interface to new DMA features of drivers.

	* vmeUniverse/vme_amd_defs.h: Added definition for data-width
	hint bits (VME_MODE_DBWxx).


	* vmeUniverse/vmeTsi148.c: added DMA support. Added support for
	data-width hint/modifier bits.

	* vmeUniverse/vmeUniverse.c, vmeUniverse/vmeUniverse.h:
	Added support for data-width hint/modifier bits.
	Added support for xxx_BLT, xxx_MBLT address modifiers.
	Restrict DBW to 32 in non-MBLT modes (except single-beat;
	a comment is in README.universe). Updated DMA support to
	implement new VMEDMA.h API. Added support for non-incrementing
	VME addresses. Restrict data width to 32 for single-beat AMs
	when the universe would use MBLT for DMA.
