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

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

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

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