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

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

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