Liao Chang	6261586e0c	RISC-V: Add kexec_file support This patch adds support for kexec_file on RISC-V. I tested it on riscv64 QEMU with busybear-linux and single core along with the OpenSBI firmware fw_jump.bin for generic platform. On SMP system, it depends on CONFIG_{HOTPLUG_CPU, RISCV_SBI} to resume/stop hart through OpenSBI firmware, it also needs a OpenSBI that support the HSM extension.

RISC-V: Add kexec_file support

This patch adds support for kexec_file on RISC-V. I tested it on riscv64
QEMU with busybear-linux and single core along with the OpenSBI firmware
fw_jump.bin for generic platform.

On SMP system, it depends on CONFIG_{HOTPLUG_CPU, RISCV_SBI} to
resume/stop hart through OpenSBI firmware, it also needs a OpenSBI that
support the HSM extension.
