Enables an IPE policy to be enforced from kernel start, enabling access control based on trust from kernel startup. This is accomplished by transforming an IPE policy indicated by CONFIG_IPE_BOOT_POLICY into a c-string literal that is parsed at kernel startup as an unsigned policy.

This option enables the Integrity Policy Enforcement LSM

control. A key feature of IPE is a customizable policy to allow

admins to reconfigure trust requirements on the fly.
