/*
BIOS_INFO structure is the base of the firmware volume layout for Intel platform BIOS implementation
so security checker module can run based on the structure and throw warnings, error or deadloop
when any unexpected firmware volumes are detected.
BIOS_INFO is recommended to support full entries of firmware volumes present in a flash
with right type, attribute, version, flash map base address and size,
all associated information which is defined by BIOS_INFO_STRUCT structure.
- IBB firmware volumes, which are expected to be measured or/and verified
by hardware base security solution to meet SecureBoot chain of trust
(Intel BootGuard for example), have attribute 0x0.
- Post IBB firmware volumes, which are expected to be measured or/and verified
by BIOS (TCG code for measurement, RSA2048SHA256Sign algorithm for verification for example),
have attribute BIOS_INFO_STRUCT_ATTRIBUTE_BIOS_POST_IBB.
- Else, follows Firmware Interface Table specification.
