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.
