- Sort all sections in the INF file. - Remove unused packages (MdeModulePkg) and lib classes (BaseMemoryLib) from the INF file. - Restrict some lib classes (BaseLib, HobLib) and GUIDs (gEfiXenInfoGuid) to IA32 and X64, in the INF file; only the IA32/X64 Xen implementation requires these. - Don't make "SmbiosPlatformDxe.h" #include everything just as a convenience. Spell out directly needed #includes in every file (annotate each with an example identifier consumed), drop unused #includes. - Keep #includes sorted. - Remove the leading underscore from the #include guard macro name in "SmbiosPlatformDxe.h".
