AMD's new Secure Encrypted Virtualization (SEV) feature allows the
memory contents of virtual machines to be transparently encrypted with a
key unique to the VM. The programming and management of the encryption
keys are handled by the AMD Secure Processor (AMD-SP) which exposes the
commands for these tasks. The complete spec is available at:
http://support.amd.com/TechDocs/55766_SEV-KM%20API_Specification.pdf
Extend the AMD-SP driver to provide the following support:
- an in-kernel API to communicate with the SEV firmware. The API can be
used by the hypervisor to create encryption context for a SEV guest.
- a userspace IOCTL to manage the platform certificates.

The Platform Security Processor (PSP) is part of the AMD Secure
Processor (AMD-SP) functionality. The PSP is a dedicated processor
that provides support for key management commands in Secure Encrypted
Virtualization (SEV) mode, along with software-based Trusted Execution
Environment (TEE) to enable third-party trusted applications.
Note that the key management functionality provided by the SEV firmware
can be used outside of the kvm-amd driver hence it doesn't need to
depend on CONFIG_KVM_AMD.
