The purpose of this series is to provide the UEFI ResetSystem() service at runtime on RISC-V systems.
With SBI v0.3 a system reset extension is available. This allows to implement reboot and poweroff in U-Boot in a system independent way.
OpenSBI already provides an implementation of the extension for the Kendryte K210 and other platforms.
* Provide a system reset driver using the system reset extension. * Enable the driver on the MAIX board. * Change the sbi command to use contants instead of raw numbers where applicable.
Heinrich Schuchardt (5): risv: add missing SBI extension definitions cmd/sbi: use constants instead of numerical values sysreset: provide SBI based sysreset driver pinctrl: K210_PINCTRL depends on REGMAP and on SYSCON maix: enable SBI system reset for MAIX
