1 The /config node (Configuration Options)
2 ----------------------------------------
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().
11 If present and non-zero, the console is silenced by default on boot.
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
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.
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.
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,
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
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.
