154 The very first instruction acts as a switch, since it's carefully
155 chosen to be a NOP in one mode and a branch in the other, so the
156 code would only be executed if not already in AArch64.

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

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

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

262 bool "JEDEC DDR3-800E / DDR3-1066G / DDR3-1333J"

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

277 Set the dram odt correction value (range -255 - 255). In allwinner
278 fex files, this option is found in bits 8-15 of the u32 odt_en variable
279 in the [dram] section. When bit 31 of the odt_en variable is set
280 then the correction is negative. Usually the value for this is 0.
