The TOCTOU vulnerability allow that the physical present person to replace the
code with the normal BootGuard check and PCR0 value.
The issue occur when BootGuard measure IBB and access flash code after NEM
disable.
the reason why we access the flash code is that we have some pointer to flash.
To avoid this vulnerability, we need to convert those pointers, the patch
series do this work and make sure that no code will access flash address.
