[PATCH v6 0/4] riscv: enable SBI system reset

[Heinrich Schuchardt]

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.

v6:
	* enable SYSRESET_SBI for qemu-riscvXX_spl_defconfig
v5:
	* add a configuration actually using the driver
	* don't add __efi_runtime in arch/riscv/lib/sbi.c
	* use '=' not ':' in array initialization with enum indices
	* enable SYSRESET_SBI for qemu-riscvXX_smode_defconfig
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 (4):
  riscv: add missing SBI extension definitions
  cmd/sbi: use constants instead of numerical values
  sysreset: provide SBI based sysreset driver
  configs: enable SYSRESET_SBI on qemu-riscvXX_smode_defconfig
