	# We use the rockchip proprietary blob to initialize memory chips
	# instead of letting u-boot doing the job. Such devices, like xt-mx4vr-v01, have DDR2
	# or LPDDR2 memories and the blob is better suited for the job.
	# Also it may come handy when there are different memory flavours among boards, with
	# different timings, specs and frequencies.
	# The rockchip proprietary blob is a drop-in substitute for the u-boot tpl.
	# In case you want to use the u-boot TPL remember to set the proper timing
	# registers in device tree and this command line instead of the other one:
