Hello hpa,
I could be wrong and the cold/warm reset values in CF9 end up having
exactly the same function as the magic BIOS signature does; if so, then

The thing is that the existing "warm" and "cold" means something different, I
believe (skip post vs do post.) It is possible it just works, but it would be
good to know which platforms or works on.
Also, why do you need the cf9 boot method at all? All current systems * should

We have tested both warm and cold reboot on our x86 platform, and it works well.
Besides with commit, the expected warm and reboot type can be specified through
command line.

Careful. This is a very different definition of warm vs cold boot used
elsewhere.
