To place "elfcorehdr=" or "memmap="/"usable-memory=" into the command
line, one needs to know where it is valid to place it. Appending doesn't
always work, as per the example above with 51e158c12aca3c9a.

So, are you now suggesting that we put both "elfcorehdr=" and
"usable-memory=" under /chosen in dtb? That's fair enough.
(as far as nobody cares about incompatibility with other archs.)

You may need move is_kdump_kernel as a weak function so that in arm64 you
can still use it in kdump kernel.

Ignore the comment please, you just use a different way to set the variable
is_kdump_kernel will still work..

It is pretty fine to use dtb along with usable memories then.

Thanks
Dave
