[edk2-devel] [PATCH v3 11/14] MdeModulePkg: Transition SMM MAT Logic to Use ImagePropertiesRecordLib
Taylor Beebe
t at taylorbeebe.com
Tue Jul 25 01:35:10 UTC 2023
Now that the bugs are fixed in the MAT logic, we can remove the
duplicate logic from PiSmmCore/MemoryAttributesTable.c and use
ImagePropertiesRecordLib instead.
