189 Set the dram controller tpr3 parameter. This parameter configures
190 the delay on the command lane and also phase shifts, which are
191 applied for sampling incoming read data. The default value 0
192 means that no phase/delay adjustments are necessary. Properly
193 configuring this parameter increases reliability at high DRAM
196 config DRAM_DQS_GATING_DELAY
197 hex "sunxi dram dqs_gating_delay value"
200 Set the dram controller dqs_gating_delay parmeter. Each byte
201 encodes the DQS gating delay for each byte lane. The delay
202 granularity is 1/4 cycle. For example, the value 0x05060606
203 means that the delay is 5 quarter-cycles for one lane (1.25
204 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
205 The default value 0 means autodetection. The results of hardware
206 autodetection are not very reliable and depend on the chip
207 temperature (sometimes producing different results on cold start
208 and warm reboot). But the accuracy of hardware autodetection
209 is usually good enough, unless running at really high DRAM
210 clocks speeds (up to 600MHz). If unsure, keep as 0.

229 used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
230 or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
231 that down binning to DDR3-1066F is supported (because DDR3-1066F
