   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.
