38 default 312 if MACH_SUN6I || MACH_SUN8I

41 Set the dram clock speed, valid range 240 - 480, must be a multiple
44 if MACH_SUN5I || MACH_SUN7I
46 int "sunxi mbus clock speed"
49 Set the mbus clock speed. The maximum on sun5i hardware is 300MHz.
54 int "sunxi dram zq value"
55 default 123 if MACH_SUN4I || MACH_SUN5I || MACH_SUN6I || MACH_SUN8I

66 Set the dram controller emr1 value.
69 int "sunxi dram odt_en value"
72 Set the dram controller odt_en parameter. This can be used to
73 enable/disable the ODT feature.
76 hex "sunxi dram tpr3 value"
79 Set the dram controller tpr3 parameter. This parameter configures
80 the delay on the command lane and also phase shifts, which are
81 applied for sampling incoming read data. The default value 0
82 means that no phase/delay adjustments are necessary. Properly
83 configuring this parameter increases reliability at high DRAM
86 config DRAM_DQS_GATING_DELAY
87 hex "sunxi dram dqs_gating_delay value"
90 Set the dram controller dqs_gating_delay parmeter. Each byte
91 encodes the DQS gating delay for each byte lane. The delay
92 granularity is 1/4 cycle. For example, the value 0x05060606
93 means that the delay is 5 quarter-cycles for one lane (1.25
94 cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
95 The default value 0 means autodetection. The results of hardware
96 autodetection are not very reliable and depend on the chip
97 temperature (sometimes producing different results on cold start
98 and warm reboot). But the accuracy of hardware autodetection
99 is usually good enough, unless running at really high DRAM
100 clocks speeds (up to 600MHz). If unsure, keep as 0.

104 default DRAM_TIMINGS_VENDOR_MAGIC
106 Select the timings of the DDR3 chips.

113 config DRAM_TIMINGS_DDR3_1066F_1333H
114 bool "JEDEC DDR3-1333H with down binning to DDR3-1066F"
116 Use the timings of the standard JEDEC DDR3-1066F speed bin for
117 DRAM_CLK <= 533MHz and the timings of the DDR3-1333H speed bin
118 for DRAM_CLK > 533MHz. This covers the majority of DDR3 chips
119 used in Allwinner A10/A13/A20 devices. In the case of DDR3-1333
120 or DDR3-1600 chips, be sure to check the DRAM datasheet to confirm
121 that down binning to DDR3-1066F is supported (because DDR3-1066F
122 uses a bit faster timings than DDR3-1333H).
124 config DRAM_TIMINGS_DDR3_800E_1066G_1333J
125 bool "JEDEC DDR3-800E / DDR3-1066G / DDR3-1333J"
127 Use the timings of the slowest possible JEDEC speed bin for the
128 selected DRAM_CLK. Depending on the DRAM_CLK value, it may be
129 DDR3-800E, DDR3-1066G or DDR3-1333J.

153 bool "SPL/FEL mode support"
157 This enables support for Fast Early Loader (FEL) mode. This
158 allows U-Boot to be loaded to the board over USB by the on-chip
159 boot rom. U-Boot should be sent in two parts: SPL first, with
160 'fel write 0x2000 u-boot-spl.bin; fel exe 0x2000' then U-Boot with
161 'fel write 0x4a000000 u-boot.bin; fel exe 0x4a000000'. This option
162 shrinks the amount of SRAM available to SPL, so only enable it if
163 you need FEL. Note that enabling this option only allows FEL to be
164 used; it is still possible to boot U-Boot from boot media. U-Boot
165 SPL detects when it is being loaded using FEL.
168 bool "UART0 on MicroSD breakout board"
172 Repurpose the SD card slot for getting access to the UART0 serial
173 console. Primarily useful only for low level u-boot debugging on
174 tablets, where normal UART0 is difficult to access and requires
175 device disassembly and/or soldering. As the SD card can't be used
176 at the same time, the system can be only booted in the FEL mode.
177 Only enable this if you really know what you are doing.

308 Say Y here if you've a board which uses opendrain drivers for the vga
309 hsync and vsync signals. Opendrain drivers cannot generate steep enough
