[PATCH v2 0/3] 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.

* Provide a system reset driver using the system reset extension.

v2:
	correct constants in patch 1 which were copied from incorrect Linux
	avoid a superfluous check in the sysreset driver
	drop K210 specific patches which need further work

Heinrich Schuchardt (3):
  risv: add missing SBI extension definitions
  cmd/sbi: use constants instead of numerical values
  sysreset: provide SBI based sysreset driver
