1 | The /config node (Configuration Options) |
| 2 | ---------------------------------------- | |
| 3 | ||
| 4 | A number of run-time configuration options are provided in the /config node | |
| 5 | of the control device tree. You can access these using fdtdec_get_config_int(), | |
| 6 | fdtdec_get_config_bool() and fdtdec_get_config_string(). | |
| 7 | ||
| 8 | Available options are: | |
| 9 | ||
| 10 | silent-console | |
| 11 | If present and non-zero, the console is silenced by default on boot. | |
| 12 | ||
| 13 | no-keyboard | |
| 14 | Tells U-Boot not to expect an attached keyboard with a VGA console | |

| 16 | u-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. | |

24 | u-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. | |

33 | u-boot,mmc-env-offset |
| 34 | u-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. | |

45 | u-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. | |

| 50 | sysreset-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. |
