Subject: [edk2-platforms][PATCH v3 2/4] S3FeaturePkg: Implement working S3 resume
Follow-up commits to MinPlatform (PeiFspWrapperHobProcessLib for
memory) and FSP-related board libraries (policy overrides) required for successful S3 resume.
Factored allocation logic into new module to avoid MinPlatform dependency on S3Feature package.
TODO: Can optimise required size.
