    crypto: ccp: Add Platform Security Processor (PSP) device support · 2a6170df
    Brijesh Singh authored
    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.
