[Fastboot] kexec supported on bookE?

[kc nainwal]

Hi,

Is kexec support available on ppc bookE architecture? I am interested in
seeing how exactly identity mapping is implemented there as MMU translation
can't be turned off.
Please copy me, as I'm not part of the mailing list.

Thanks in advance,

I don't know about ppc bookE but on x86_64 where mmu cannot be turned
off we setup an identity mapped page table with the larges pages
available. I don't see why that would not work in general.
