Change 208890 by rwatson at rwatson_svr_ctsrd_mipsbuild on 2012/03/31 19:28:31

	Checkpoint a partial FreeBSD storage driver for the Altera
	University Program SD Card IP Core.
	
	The Altera core provides a much lower-level interface than is
	used by the sdhci(4) driver, as well as supporting neither
	interrupts nor DMA.  Implement a timer-driver framework that
	handles the higher-level aspects of using the IP Core, such as
	detecting card insertion/removal, timer-driven I/O, etc.
	
	The very bottom end of the driver isn't yet implemented, as I
	am still working my way through a blend of the SD Card physical
	interface and Altera IP core specifications, but figured it
	best to check in this non-trivial work-in-progress on
	principle.
