Before introducing the SMM driver interface, clean up #include directives and [LibraryClasses] by: - removing what's not directly used (HobLib and UefiLib), - adding what's used but not spelled out (DevicePathLib), - sorting the result. This helps with seeing each source file's dependencies and with determining the library classes for the SMM driver.

Abstract:
|
|
|
|
Defines data structure that is the volume header found.These data is intent
