Change 209863 by rwatson at rwatson_cinnamon on 2012/04/19 23:37:19

	A bit of late-night kernel hacking: start to make gxemul its own
	MIPS platform, rather than conflating it with BERI for local testing
	purposes in the CTSRD project.  A gxemul_machdep.c is still required
	-- and perhaps can be lifted, or simply used, from MALTA.
	
	Put gxemul's console driver in its own dev/gxemul tree, in
	anticipation of future gxemul-specific drivers.
