PSPTool is a Swiss Army knife for dealing with firmware of the AMD Secure Processor (formerly known as Platform Security Processor or PSP). It locates AMD firmware inside UEFI images as part of BIOS updates targeting AMD platforms. PSPTrace can be used to correlate an SPI capture of a boot procedure recorded with a Saleae Logic analyzer to the PSP firmware of a UEFI image.
