Change 209211 by rwatson at rwatson_svr_ctsrd_mipsbuild on 2012/04/07 17:26:16

	Adjust BERI configuration based on local documentation changes;
	it's a reference configuration for using a memory file system, so
	comment on that.
	
	Add a BERI_SDROOT configuration file that will be used for booting
	from the Altera SD Card IP Core.
