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

227 used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
228 or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
229 that down binning to DDR3-1066F is supported (because DDR3-1066F
230 uses a bit faster timings than DDR3-1333H).

249 fex files, this option is found in bits 8-15 of the u32 odt_en variable
250 in the [dram] section. When bit 31 of the odt_en variable is set
251 then the correction is negative. Usually the value for this is 0.
