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

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

187 bool "SPL/FEL mode support"
191 This enables support for Fast Early Loader (FEL) mode. This
192 allows U-Boot to be loaded to the board over USB by the on-chip
193 boot rom. U-Boot should be sent in two parts: SPL first, with
194 'fel write 0x2000 u-boot-spl.bin; fel exe 0x2000' then U-Boot with
195 'fel write 0x4a000000 u-boot.bin; fel exe 0x4a000000'. This option
196 shrinks the amount of SRAM available to SPL, so only enable it if
197 you need FEL. Note that enabling this option only allows FEL to be
198 used; it is still possible to boot U-Boot from boot media. U-Boot
199 SPL detects when it is being loaded using FEL.
202 bool "UART0 on MicroSD breakout board"
206 Repurpose the SD card slot for getting access to the UART0 serial
207 console. Primarily useful only for low level u-boot debugging on
208 tablets, where normal UART0 is difficult to access and requires
209 device disassembly and/or soldering. As the SD card can't be used
210 at the same time, the system can be only booted in the FEL mode.
211 Only enable this if you really know what you are doing.
213 config OLD_SUNXI_KERNEL_COMPAT
214 boolean "Enable workarounds for booting old kernels"
217 Set this to enable various workarounds for old kernels, this results in
218 sub-optimal settings for newer kernels, only enable if needed.
221 string "Card detect pin for mmc0"
