[PATCH 0/5] riscv: enable SBI system reset

[Heinrich Schuchardt]

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
