      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
     15 
     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.
     23 
     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.
     32 
     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.
     44 
     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.
     49 
     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.
