[PATCH 0/7] Kexec-tools: Improve RISC-V port

[Song Shuai]

Hi,

This series is created to improve RISC-V port of kexec-tools,
and is based on the horms/kexec-tools:build-test-riscv-v2 branch.

For your convenience, here is my Github branch for kexec-tools:
https://github.com/sugarfillet/kexec-tools/commits/rv-Image

The first four patches fixes some build or runtime issues:  

  RISC-V: Use linux,usable-memory-range for crash kernel
  RISC-V: Fix the undeclared ‘EM_RISCV’ build failure
  RISC-V: Get memory ranges from iomem
  RISC-V: Correct the usage of command line option

The last three patches enable the kexec_file_load syscall to load
vmlinux and support loading Image binary file for two syscalls.

  RISC-V: Enable kexe_file_load
  RISC-V: Separate elf_riscv_find_pbase out
  RISC-V: Support loading Image binary file

Note that: 

RISC-V Linux kexec_load_file's support for Image file has been sent out but not merged [1].
