REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2673
M mean that Measured Boot, V mean that Verified Boot.
The FvReport do below:
1. Do nothing if neither M nor V
2. Allocate pages to save the firmware volume and use it to install
firmware info Ppi
3. Install PreHashFv Ppi if the FV need measurement.
4. Verify the Hash if the FV need verification
Notes:
1. The component is used to verify the FV or measure the FV
2. Copy action is just for security purpose but not main purpose.
3. If you use this component, Doesn't need to copy in other compoent
which result time consumption.
