[PATCH v3 0/8] (kexec-tools) arm64: add kdump support

[AKASHI Takahiro]

My kernel patches of kdump suport on arm64 are currently under reviews.

This patchset is synced with them (v26 [1]) and provides necessary changes
for kexec-tools. It should be applied on top of Geoff's kexec-tools patches
v5[2] along with a bugfix[3].

Changes for v3:
 - rebased on Geoff's v5
 - fix a value of estimated PHYS_OFFSET
 - add a kernel code/data segment because they now reside out of linear
   mapping due to KASLR introduction
 - remove "linux,usable-memory-range" dependency, instead using
   "reserved-memory" node
 - add -mem-min/-mem-max support

Changes for v2:
 - trim a temoprary buffer in setup_2nd_dtb()
 - add patch#6("kexec: generalize and rename get_kernel_stext_sym()")
 - update patch#7 from Pratyush
   (re-worked by akashi)

  arm64: kdump: add elf core header segment
  arm64: kdump: set up kernel image segment
  arm64: kdump: set up other segments
  arm64: kdump: add DT properties to crash dump kernel's dtb

Pratyush Anand (2):
  kexec: generalize and rename get_kernel_stext_sym()
  arm64: kdump: Add support for binary image files
