+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.
