AMD Platform Security Processor (PSP) error

What this error means

AMD Platform Security Processor (PSP) error is a high-severity processor (CPU) issue. The AMD Platform Security Processor (PSP) is an ARM Cortex-A5 security coprocessor embedded in AMD CPUs and APUs. A PSP error typically manifests as a boot failure with debug LED codes or BIOS error messages. PSP handles secure boot validation, fTPM operations, and AMD Memory Guard encryption. Errors here block system initialization. This can also stem from incompatible AGESA version. The steps below are ordered to resolve this efficiently.
