> 
> This patch series changes the EFI configuration table information
> which is queried by the bootloader to make it more compatible with
> Intel TDX.  The first patch changes the ABI to make the table contain
> two 64 bit integers instead of two 32 bit ones.  The second patch is a
> cosmetic one to change the names of the GUIDs and tables to have a
> confidential computing prefix instead of a SEV Launch one.
> 
> The first patch *must* be applied before the next stable tag to avoid
> ABI breakage.  The second is purely cosmetic and doesn't change the
> code output.
> 
> Ultimately there will still need to be a TDX collector for the secret,
> which would feed the value into the SecretDxe, but these changes
> should ensure that no further changes would be required by the secret
> consumers.
