crypto: ccp - Add GET_ID SEV command
The GET_ID command, added as of SEV API v0.16, allows the SEV firmware to be queried about a unique CPU ID. This unique ID can then be used to obtain the public certificate containing the Chip Endorsement Key (CEK) public key signed by the AMD SEV Signing Key (ASK). For more information please refer to "Section 5.12 GET_ID" of https://support.amd.com/TechDocs/55766_SEV-KM%20API_Specification.pdf Signed-off-by: Janakarajan Natarajan <Janakarajan.Natarajan@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
