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.

Subject: RE: [edk2-devel] [Patch V2 5/8] MdeModulePkg: Add UefiCpuPkg.dec to pass DependencyCheck
MdePkg: Include files for industry standard and public specs and lib classes and lib implementations that support those specs
If all the IA32/X64 CPU header files to support the CpuPageTableLib class are in the MdePkg, then we could consider
moving he class to MdePkg and avoid this patch.
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.
Thanks,
Mike

Mike,
What's the rule regarding content in mdepkg and cpupkg?

If components outside the UefiCpuPkg need access to the CpuPageTableLib, should we
consider moving CpuPageTableLib to MdePkg or MdeModulePkg? 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?
