Back in 2019, I had proposed some more generic rules for package dependencies. https://edk2.groups.io/g/devel/message/52211 https://github.com/mdkinney/edk2/wiki/EDKII-Packages#edk-ii-package-dependency-rules The EDK II DEC files do not have enough meta-data to apply these rules. Would require some extra Define values or well-known tags in comments. The current package dependency checker uses a set of named packages.

The current CpuPageTableLib looks IA32/X64 specific. Should it follow the naming conventions in the EDK II C Coding Style Spec updated by Abner? It does not look like the current CpuPageTableLib APIs would apply to other CPU archs. MdePkg does not have any modules. UefiCpuPkg contains CPU specific modules. UefiCpuPkg can also contain libs that are required by modules in the UefiCpuPkg or modules in other Si/Platform packages.

There are many different boot phases that need to crate/manage page tables, so we need to find the right common location. Perhaps the only part that needs to be moved is the lib class?
