158 Set the dram clock speed, valid range 240 - 480 (prior to sun9i),
159 must be a multiple of 24. For the sun9i (A80), the tested values
160 (for DDR3-1600) are 312 to 792.

192 Set the dram controller emr1 value.
195 hex "sunxi dram tpr3 value"
198 Set the dram controller tpr3 parameter. This parameter configures
199 the delay on the command lane and also phase shifts, which are
200 applied for sampling incoming read data. The default value 0
201 means that no phase/delay adjustments are necessary. Properly
202 configuring this parameter increases reliability at high DRAM
205 config DRAM_DQS_GATING_DELAY
206 hex "sunxi dram dqs_gating_delay value"
209 Set the dram controller dqs_gating_delay parmeter. Each byte
210 encodes the DQS gating delay for each byte lane. The delay
211 granularity is 1/4 cycle. For example, the value 0x05060606
212 means that the delay is 5 quarter-cycles for one lane (1.25
213 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
214 The default value 0 means autodetection. The results of hardware
215 autodetection are not very reliable and depend on the chip
216 temperature (sometimes producing different results on cold start
217 and warm reboot). But the accuracy of hardware autodetection
218 is usually good enough, unless running at really high DRAM
219 clocks speeds (up to 600MHz). If unsure, keep as 0.

237 for DRAM_CLK > 533MHz. This covers the majority of DDR3 chips
238 used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
239 or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
240 that down binning to DDR3-1066F is supported (because DDR3-1066F
241 uses a bit faster timings than DDR3-1333H).

247 selected DRAM_CLK. Depending on the DRAM_CLK value, it may be
248 DDR3-800E, DDR3-1066G or DDR3-1333J.
255 config DRAM_ODT_CORRECTION
256 int "sunxi dram odt correction value"
259 Set the dram odt correction value (range -255 - 255). In allwinner
260 fex files, this option is found in bits 8-15 of the u32 odt_en variable
261 in the [dram] section. When bit 31 of the odt_en variable is set
262 then the correction is negative. Usually the value for this is 0.
