Subject: OvmfPkg/AmdSev/SecretDxe: make secret location naming generic
X-Git-Tag: edk2-stable202102~333
X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=96201ae7bf97c3a2c0ef386110bb93d25e9af1ba

OvmfPkg/AmdSev/SecretDxe: make secret location naming generic

It is anticipated that this part of the code will work for both Intel
TDX and AMD SEV, so remove the SEV specific naming and change to
ConfidentialComputing as a more architecture neutral prefix. Apart
from the symbol rename, there are no code changes.
