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 missing constants
* Provide a system reset driver using the system reset extension.
* Provide a UEFI runtime implementation for system reset
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
