PSPTool: Display, extract and manipulate AMD PSP UEFI firmware

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. It is based on reverse-engineering efforts of AMD’s proprietary filesystem used to pack firmware blobs into UEFI Firmware Images. These are usually 16MB in size and can be conveniently parsed by UEFITool. However, all binary blobs by AMD are located in padding volumes unparsable by UEFITool. PSPTool favourably works with UEFI images as obtained through BIOS updates.
