Hi Simon and Akashi,
Sorry for the delay, I was out of office most of last week.

Since during the arm64 kexec_load()/kdump invocation,
the dtb is passed to the second kernel, it is sometimes useful
to dump the dtb contents (to verify the correctness
of the same).
This patch adds this feature which is enabled when '-d' flag is
used with kexec command line invocation.
This seems significantly more verbose than what -d already outputs.
Perhaps a second debug level is warranted here?

Debug messages on arm64 are already noisy due to ones from
machine_apply_elf_rel(), which are not very useful in most cases,
even making logs hard to understand.
Some sort of level be helpful here, too.
Ok, will work on the same and send out a v5 with the fixes.
Thanks,
Bhupesh
