1399f3afaSPhilipp TomsichThe /config node (Configuration Options) 2399f3afaSPhilipp Tomsich---------------------------------------- 3399f3afaSPhilipp Tomsich 4399f3afaSPhilipp TomsichA number of run-time configuration options are provided in the /config node 5399f3afaSPhilipp Tomsichof the control device tree. You can access these using fdtdec_get_config_int(), 6399f3afaSPhilipp Tomsichfdtdec_get_config_bool() and fdtdec_get_config_string(). 7399f3afaSPhilipp Tomsich 8399f3afaSPhilipp TomsichAvailable options are: 9399f3afaSPhilipp Tomsich 10399f3afaSPhilipp Tomsichsilent-console 11399f3afaSPhilipp Tomsich If present and non-zero, the console is silenced by default on boot. 12399f3afaSPhilipp Tomsich 13399f3afaSPhilipp Tomsichno-keyboard 14399f3afaSPhilipp Tomsich Tells U-Boot not to expect an attached keyboard with a VGA console 15e7dd02e3SPhilipp Tomsich 16e7dd02e3SPhilipp Tomsichu-boot,efi-partition-entries-offset 17e7dd02e3SPhilipp Tomsich If present, this provides an offset (in bytes, from the start of a 18e7dd02e3SPhilipp Tomsich device) that should be skipped over before the partition entries. 19e7dd02e3SPhilipp Tomsich This is used by the EFI/GPT partition implementation when a device 20e7dd02e3SPhilipp Tomsich is formatted. 21e7dd02e3SPhilipp Tomsich 22e7dd02e3SPhilipp Tomsich This setting will override any values configured via Kconfig. 23f222b367SPhilipp Tomsich 24c9e87ba6SJorge Ramirez-Ortizu-boot,mmc-env-partition 25c9e87ba6SJorge Ramirez-Ortiz if present, the environment shall be placed at the last 26c9e87ba6SJorge Ramirez-Ortiz CONFIG_ENV_SIZE blocks of the partition on the 27c9e87ba6SJorge Ramirez-Ortiz CONFIG_SYS_MMC_ENV_DEV. 28c9e87ba6SJorge Ramirez-Ortiz 29c9e87ba6SJorge Ramirez-Ortiz if u-boot,mmc-env-offset* is present, this setting will take 30c9e87ba6SJorge Ramirez-Ortiz precedence. In that case, only if the partition is not found, 31c9e87ba6SJorge Ramirez-Ortiz mmc-env-offset* will be tried. 32c9e87ba6SJorge Ramirez-Ortiz 33de59d10cSPhilipp Tomsichu-boot,mmc-env-offset 34de59d10cSPhilipp Tomsichu-boot,mmc-env-offset-redundant 35de59d10cSPhilipp Tomsich If present, the values of the 'u-boot,mmc-env-offset' and/or 36de59d10cSPhilipp Tomsich of the u-boot,mmc-env-offset-redundant' properties overrides 37de59d10cSPhilipp Tomsich CONFIG_ENV_OFFSET and CONFIG_ENV_OFFSET_REDUND, respectively, 38de59d10cSPhilipp Tomsich for SD/MMC devices. 39de59d10cSPhilipp Tomsich 40de59d10cSPhilipp Tomsich Values are interpreted as the offset from the start of the 41de59d10cSPhilipp Tomsich device, specified in bytes. It is assumed that the setting 42de59d10cSPhilipp Tomsich will point at the beginning of a LBA and values that are not 43de59d10cSPhilipp Tomsich LBA-aligned will be rounded up to the next LBA address. 44de59d10cSPhilipp Tomsich 45f222b367SPhilipp Tomsichu-boot,spl-payload-offset 46f222b367SPhilipp Tomsich If present (and SPL is controlled by the device-tree), this allows 47f222b367SPhilipp Tomsich to override the CONFIG_SYS_SPI_U_BOOT_OFFS setting using a value 48f222b367SPhilipp Tomsich from the device-tree. 49*ae0d33a7SPhilipp Tomsich 50*ae0d33a7SPhilipp Tomsichsysreset-gpio 51*ae0d33a7SPhilipp Tomsich If present (and supported by the specific board), indicates a 52*ae0d33a7SPhilipp Tomsich GPIO that can be set to trigger a system reset. It is assumed 53*ae0d33a7SPhilipp Tomsich that such a system reset will effect a complete platform reset, 54*ae0d33a7SPhilipp Tomsich being roughly equivalent to a power-on reset. 55
