My kernel patches of kdump support on arm64 are currently under review.
This patchset is synced with them (v30 [1]) and provides necessary changes
for kexec-tools. It can be applied on top of kexec-tools master branch.
[1] T.B.D.
Changes for v5:
- remove "linux,crashkernel-base/size" handling aligned with a change
on the kernel side
Changes for v4:
- rebased on the master branch (including Geoff's v6)
- revive "linux,usable-memory-range" DT property (from v2), dropping
use of "reserved-memory" nodes introduced in v3 (patch #8)
- extend the semantics of kexec_iomem_for_each_line() per Pratyush
(patch #1)
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)
