	---help---
	Set the dram controller tpr3 parameter. This parameter configures
	the delay on the command lane and also phase shifts, which are
	applied for sampling incoming read data. The default value 0
	means that no phase/delay adjustments are necessary. Properly
	configuring this parameter increases reliability at high DRAM
	clock speeds.

config DRAM_DQS_GATING_DELAY
	hex "sunxi dram dqs_gating_delay value"

	---help---
	Set the dram controller dqs_gating_delay parmeter. Each byte
	encodes the DQS gating delay for each byte lane. The delay
	granularity is 1/4 cycle. For example, the value 0x05060606
	means that the delay is 5 quarter-cycles for one lane (1.25
	cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
	The default value 0 means autodetection. The results of hardware
	autodetection are not very reliable and depend on the chip
	temperature (sometimes producing different results on cold start
	and warm reboot). But the accuracy of hardware autodetection
	is usually good enough, unless running at really high DRAM
	clocks speeds (up to 600MHz). If unsure, keep as 0.
