Change 209381 by rwatson at rwatson_svr_ctsrd_mipsbuild on 2012/04/10 20:13:49

	Checkpoint first cut at Terasic Multi-touch LCD (MTL) driver for
	FreeBSD/BERI.  This driver really just exports the MTL's region of
	physical address space to userspace via a memory mappable device
	node (/dev/terasic_mtllcd0), including text frame buffer, graphics
	frame buffer, and touch screen input.  A more refined and perhaps
	more granular approach might be desirable in the future so that,
	for example, we might hook up syscons(4) to the text frame buffer,
	and allow the different regions to be exported (and hence
	delegated from a Capsicum perspective) using separate device nodes.
	We might also want to allow read()/write() on it so that dd(1) can
	dump contents onto the text and graphics frame buffers easily.
