My app (UEFI spec 2.7) uses following protocols:
EFI_BOOT_SERVICES revision=C2=A0EFI_SPECIFICATION_VERSION
EFI_FILE_PROTOCOL revision 0x00020000
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL 0x00010000
EFI_PEI_SERVICES - not found in UEFI specificaion
EFI_PEI_CPU_IO_PPI - not found in UEFI specificaion

UEFI Specification 2.4 protocols:
EFI_BOOT_SERVICES revision=C2=A0EFI_SPECIFICATION_VERSION
EFI_FILE_PROTOCOL=C2=A0revision=C2=A00x00020000
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL 0x00010000

So the main services API EFI_BOOT_SERVICES, where I'm using few common fun=
ctions (OpenProtocol, AllocatePool...) differs from the EFI shell where app=
 is using. Also there are protocols such as EFI_PEI_SERVICES and EFI_PEI_CP=
U_IO_PPI about which differences I can say nothing, so it is batter to find=
 EDK2 with UEFI spec 2.4.

Thank you,
Sergey
