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

200 must be a multiple of 24. For the sun9i (A80), the tested values
201 (for DDR3-1600) are 312 to 792.

235 Set the dram controller emr1 value.
238 hex "sunxi dram tpr3 value"
241 Set the dram controller tpr3 parameter. This parameter configures
242 the delay on the command lane and also phase shifts, which are
243 applied for sampling incoming read data. The default value 0
244 means that no phase/delay adjustments are necessary. Properly
245 configuring this parameter increases reliability at high DRAM
248 config DRAM_DQS_GATING_DELAY
249 hex "sunxi dram dqs_gating_delay value"
252 Set the dram controller dqs_gating_delay parmeter. Each byte
253 encodes the DQS gating delay for each byte lane. The delay
254 granularity is 1/4 cycle. For example, the value 0x05060606
255 means that the delay is 5 quarter-cycles for one lane (1.25
256 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
257 The default value 0 means autodetection. The results of hardware
258 autodetection are not very reliable and depend on the chip
259 temperature (sometimes producing different results on cold start
260 and warm reboot). But the accuracy of hardware autodetection
261 is usually good enough, unless running at really high DRAM
262 clocks speeds (up to 600MHz). If unsure, keep as 0.

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

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

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

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