- The /config node (Configuration Options)
- ----------------------------------------
- A number of run-time configuration options are provided in the /config node
- of the control device tree. You can access these using fdtdec_get_config_int(),
- fdtdec_get_config_bool() and fdtdec_get_config_string().
- Available options are:
- silent-console
- If present and non-zero, the console is silenced by default on boot.
- no-keyboard
- Tells U-Boot not to expect an attached keyboard with a VGA console
- u-boot,efi-partition-entries-offset
- If present, this provides an offset (in bytes, from the start of a
- device) that should be skipped over before the partition entries.
- This is used by the EFI/GPT partition implementation when a device
- is formatted.
- This setting will override any values configured via Kconfig.
- u-boot,mmc-env-partition
- if present, the environment shall be placed at the last
- CONFIG_ENV_SIZE blocks of the partition on the
- CONFIG_SYS_MMC_ENV_DEV.
- if u-boot,mmc-env-offset* is present, this setting will take
- precedence. In that case, only if the partition is not found,
- mmc-env-offset* will be tried.
- u-boot,mmc-env-offset
- u-boot,mmc-env-offset-redundant
- If present, the values of the 'u-boot,mmc-env-offset' and/or
- of the u-boot,mmc-env-offset-redundant' properties overrides
- CONFIG_ENV_OFFSET and CONFIG_ENV_OFFSET_REDUND, respectively,
- for SD/MMC devices.
- Values are interpreted as the offset from the start of the
- device, specified in bytes. It is assumed that the setting
- will point at the beginning of a LBA and values that are not
- LBA-aligned will be rounded up to the next LBA address.
- u-boot,spl-payload-offset
- If present (and SPL is controlled by the device-tree), this allows
- to override the CONFIG_SYS_SPI_U_BOOT_OFFS setting using a value
- from the device-tree.
- sysreset-gpio
- If present (and supported by the specific board), indicates a
- GPIO that can be set to trigger a system reset. It is assumed
- that such a system reset will effect a complete platform reset,
- being roughly equivalent to a power-on reset.
