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

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

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

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

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

267 selected DRAM_CLK. Depending on the DRAM_CLK value, it may be
268 DDR3-800E, DDR3-1066G or DDR3-1333J.

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

310 console. Primarily useful only for low level u-boot debugging on
311 tablets, where normal UART0 is difficult to access and requires
312 device disassembly and/or soldering. As the SD card can't be used
