Admittedly they don't all support kexec from them, but they
can be kexeced into. ppc64 kexec support was merged
here:

That, and I didn't want to make changes to the code that
may be replaced with some other library later.
We could move this from kexec_platform_init to crt0_kexec.S
platform_init so it becomes platform dependent if you want
to support them.
Are there embedded firmwares that hove old device trees?
