2023-07-14env: mmc: statically set the environment partition nameEmmanuel Di Fede
The new opt-out setting, CONFIG_ENV_MMC_PARTITION, statically sets the MMC environment partition name. Prior to this patch, the only way to declare this partition name was by creating a 'u-boot,mmc-env-partition' parameter in the device-tree's /config node. This setting provides additional flexibility, particularly in cases where accessing the device-tree is not straightforward (e.g. QEMU). If undeclared, the device-tree's setting will be used.

2021-09-25treewide: fdt: Move fdt_get_config_... to ofnode_conf_read...Simon Glass
The current API is outdated as it requires a devicetree pointer. Move these functions to use the ofnode API and update this globally. Add some tests while we are here. Correct the call in exynos_dsim_config_parse_dt() which is obviously wrong. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-09-11doc: Tidy up the bindings for the config/ nodeSimon Glass
Sort these and add a type so it is clear how to set the value. Add a note about usage to the top. Correct the 'no-keyboard' binding which is missing a prefix.

2017-11-30rockchip: rk3399-puma: add code to allow forcing a power-on resetPhilipp Tomsich
The reset circuitry in the RK3399 only resets 'almost all logic' when a software reset is performed. To make our software maintenance easier in the future, we want to have the option (controlled by a DTS property) to force all reset causes other than a power-on reset to trigger a power-on reset via a GPIO trigger. This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7) board-support and the documentation for the new property (sysreset-gpio) within the /config-node.
