PS1:
> I'm sorry but what is 'ubsan'?

Sorry, that's the 'Undefined Behavior Sanitizer'. It's something you can compile
into coreboot (should be in Kconfig somewhere) and it would tell you if the code
does something undefined.

In this case, I guess the void-pointer arithmetic would count as undefined. But
that's not to worry about because we know what GCC does with it. The code could
probably be written without the void pointers, maybe even without the variables.
But that's out of scope of this change.
