RH-Commit: [11/20] c7b9cd1b716e1b8163b8094fbea8117241901815
|
|
|
|
Only accept gEfiAuthenticatedVariableGuid when checking the variable
|
|
store header in ValidateFvHeader().
|
|
|
|
The edk2 code base has been switched to use the authenticated varstore
|
|
format unconditionally (even in case secure boot is not used or
|
|
supported) a few years ago.
