93 Set the dram controller odt_en parameter. This can be used to
94 enable/disable the ODT feature.
97 hex "sunxi dram tpr3 value"
100 Set the dram controller tpr3 parameter. This parameter configures
101 the delay on the command lane and also phase shifts, which are
102 applied for sampling incoming read data. The default value 0
103 means that no phase/delay adjustments are necessary. Properly
104 configuring this parameter increases reliability at high DRAM
107 config DRAM_DQS_GATING_DELAY
108 hex "sunxi dram dqs_gating_delay value"
111 Set the dram controller dqs_gating_delay parmeter. Each byte
112 encodes the DQS gating delay for each byte lane. The delay
113 granularity is 1/4 cycle. For example, the value 0x05060606
114 means that the delay is 5 quarter-cycles for one lane (1.25
115 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
116 The default value 0 means autodetection. The results of hardware
117 autodetection are not very reliable and depend on the chip
118 temperature (sometimes producing different results on cold start
119 and warm reboot). But the accuracy of hardware autodetection
120 is usually good enough, unless running at really high DRAM
121 clocks speeds (up to 600MHz). If unsure, keep as 0.

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

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

174 bool "SPL/FEL mode support"
178 This enables support for Fast Early Loader (FEL) mode. This
179 allows U-Boot to be loaded to the board over USB by the on-chip
180 boot rom. U-Boot should be sent in two parts: SPL first, with
181 'fel write 0x2000 u-boot-spl.bin; fel exe 0x2000' then U-Boot with
182 'fel write 0x4a000000 u-boot.bin; fel exe 0x4a000000'. This option
183 shrinks the amount of SRAM available to SPL, so only enable it if
184 you need FEL. Note that enabling this option only allows FEL to be
185 used; it is still possible to boot U-Boot from boot media. U-Boot
186 SPL detects when it is being loaded using FEL.
189 bool "UART0 on MicroSD breakout board"
193 Repurpose the SD card slot for getting access to the UART0 serial
194 console. Primarily useful only for low level u-boot debugging on
195 tablets, where normal UART0 is difficult to access and requires
196 device disassembly and/or soldering. As the SD card can't be used
197 at the same time, the system can be only booted in the FEL mode.
198 Only enable this if you really know what you are doing.

208 sub-optimal settings for newer kernels, only enable if needed.

298 This allows enabling I2C/TWI controller 0 by muxing its pins, enabling
