1The /config node (Configuration Options)
2----------------------------------------
3
4A number of run-time configuration options are provided in the /config node
5of the control device tree. You can access these using fdtdec_get_config_int(),
6fdtdec_get_config_bool() and fdtdec_get_config_string().
7
8Available options are:
9
10silent-console
11	If present and non-zero, the console is silenced by default on boot.
12
13no-keyboard
14	Tells U-Boot not to expect an attached keyboard with a VGA console
15
16u-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
24u-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
33u-boot,mmc-env-offset
34u-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
45u-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
50sysreset-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.
