127 Set the dram controller tpr3 parameter. This parameter configures
128 the delay on the command lane and also phase shifts, which are
129 applied for sampling incoming read data. The default value 0
130 means that no phase/delay adjustments are necessary. Properly
131 configuring this parameter increases reliability at high DRAM
134 config DRAM_DQS_GATING_DELAY
135 hex "sunxi dram dqs_gating_delay value"
138 Set the dram controller dqs_gating_delay parmeter. Each byte
139 encodes the DQS gating delay for each byte lane. The delay
140 granularity is 1/4 cycle. For example, the value 0x05060606
141 means that the delay is 5 quarter-cycles for one lane (1.25
142 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
143 The default value 0 means autodetection. The results of hardware
144 autodetection are not very reliable and depend on the chip
145 temperature (sometimes producing different results on cold start
146 and warm reboot). But the accuracy of hardware autodetection
147 is usually good enough, unless running at really high DRAM
148 clocks speeds (up to 600MHz). If unsure, keep as 0.

165 DRAM_CLK <= 533MHz and the timings of the DDR3-1333H speed bin
166 for DRAM_CLK > 533MHz. This covers the majority of DDR3 chips
167 used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
168 or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
169 that down binning to DDR3-1066F is supported (because DDR3-1066F
170 uses a bit faster timings than DDR3-1333H).

177 DDR3-800E, DDR3-1066G or DDR3-1333J.

185 int "sunxi dram odt correction value"
188 Set the dram odt correction value (range -255 - 255). In allwinner
189 fex files, this option is found in bits 8-15 of the u32 odt_en variable
190 in the [dram] section. When bit 31 of the odt_en variable is set
191 then the correction is negative. Usually the value for this is 0.

217 console. Primarily useful only for low level u-boot debugging on
218 tablets, where normal UART0 is difficult to access and requires
