Change 210345 by rwatson at rwatson_svr_ctsrd_mipsbuild on 2012/04/29 09:50:26

	Remove exist stub MTL driver, which simply allowed memory mapping
	of the Terasic MTL's memory from userspace via a special device node,
	and replace with a larger driver suite, consisting of several
	sub-drivers capturing various aspects of MTL behaviour:
	
	- Simple memory-mapped driver for the MTL pixel frame buffer
	- Simple memory-mapped driver for the MTL control register set
	- Simple memory-mapped driver for the MTL text frame buffer
	- More complex syscons driver for the MTL text frame buffer
	
	In the future we will want to provide an ioctl-driver control path
	for the register set from both the driver-provided device nodes,
	and perhaps via syscons.  Although in hardware there is significant
	overlap with the flash device on the DE4 due to sharing a physical		bus, it is likely the DE4 flash driver for FreeBSD will be entirely
	independent in practice.
	
	This is just a code checkpoint, and will likely require significant
	refinement for the syscons aspects to work properly.
