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

In the case of DDR3-1333 or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm that down binning to DDR3-1066F is supported (because DDR3-1066F uses a bit faster timings than DDR3-1333H). config DRAM_TIMINGS_DDR3_800E_1066G_1333J bool "JEDEC DDR3-800E / DDR3-1066G / DDR3-1333J" ---help--- Use the timings of the slowest possible JEDEC speed bin for the selected DRAM_CLK.

This option shrinks the amount of SRAM available to SPL, so only enable it if you need FEL. Note that enabling this option only allows FEL to be used; it is still possible to boot U-Boot from boot media.

Primarily useful only for low level u-boot debugging on tablets, where normal UART0 is difficult to access and requires device disassembly and/or soldering.
