1The /config node (Configuration Options) 2---------------------------------------- 3 4A number of run-time configuration options are provided in the /config node 5of the control device tree. You can access these using fdtdec_get_config_int(), 6fdtdec_get_config_bool() and fdtdec_get_config_string(). 7 8Available options are: 9 10silent-console 11 If present and non-zero, the console is silenced by default on boot. 12 13no-keyboard 14 Tells U-Boot not to expect an attached keyboard with a VGA console 15 16u-boot,efi-partition-entries-offset 17 If present, this provides an offset (in bytes, from the start of a 18 device) that should be skipped over before the partition entries. 19 This is used by the EFI/GPT partition implementation when a device 20 is formatted. 21 22 This setting will override any values configured via Kconfig. 23 24u-boot,mmc-env-partition 25 if present, the environment shall be placed at the last 26 CONFIG_ENV_SIZE blocks of the partition on the 27 CONFIG_SYS_MMC_ENV_DEV. 28 29 if u-boot,mmc-env-offset* is present, this setting will take 30 precedence. In that case, only if the partition is not found, 31 mmc-env-offset* will be tried. 32 33u-boot,mmc-env-offset 34u-boot,mmc-env-offset-redundant 35 If present, the values of the 'u-boot,mmc-env-offset' and/or 36 of the u-boot,mmc-env-offset-redundant' properties overrides 37 CONFIG_ENV_OFFSET and CONFIG_ENV_OFFSET_REDUND, respectively, 38 for SD/MMC devices. 39 40 Values are interpreted as the offset from the start of the 41 device, specified in bytes. It is assumed that the setting 42 will point at the beginning of a LBA and values that are not 43 LBA-aligned will be rounded up to the next LBA address. 44 45u-boot,spl-payload-offset 46 If present (and SPL is controlled by the device-tree), this allows 47 to override the CONFIG_SYS_SPI_U_BOOT_OFFS setting using a value 48 from the device-tree. 49 50sysreset-gpio 51 If present (and supported by the specific board), indicates a 52 GPIO that can be set to trigger a system reset. It is assumed 53 that such a system reset will effect a complete platform reset, 54 being roughly equivalent to a power-on reset. 55
