[edk2-devel] [PATCH 0/2] Update SevSecret API to work for TDX

[James Bottomley]

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.
