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 missing constants * Provide a system reset driver using the system reset extension.
v4: * remove the UEFI SystemReset() implementation * simplify the code using an array to translate reset types * remove a superfluos check to determine if the device was probed v3: add SBI_HSM_HART_STATUS_SUSPENDED, SBI_HSM_HART_STATUS_SUSPEND_PENDING, SBI_HSM_HART_STATUS_RESUME_PENDING v2: correct constants that were blindly copied from Linux
Heinrich Schuchardt (3): riscv: add missing SBI extension definitions cmd/sbi: use constants instead of numerical values sysreset: provide SBI based sysreset driver
