Hi Lorenzo,
Was going through this comment. The patch currently uses a 32 bit
cookie. The spec also talks about "SMC64 - uint64 - cookie". Can you
please suggest if we should add support for 64 bit cookie here?
This will require a re-design for supporting about up-to three 32-bit
numbers in reboot-mode framework.
thanks,
Shivendra
