Hi,

In UefiSpec.h, we define the UEFI version 2.7 in system table.

#define EFI_2_70_SYSTEM_TABLE_REVISION (( 2 << 16 ) | ( 70 ))
#define EFI_SYSTEM_TABLE_REVISION EFI_2_70_SYSTEM_TABLE_REVISION
#define EFI_SPECIFICATION_VERSION EFI_SYSTEM_TABLE_REVISION
#define EFI_RUNTIME_SERVICES_REVISION EFI_SPECIFICATION_VERSION

In Linux dmesg
[=C2=A0=C2=A0=C2=A0 0.000000] efi: EFI v2.70 by EDK II

Shall it be updated to v2.8 to align with UEFI spec?

Thanks,
Derek
