[coreboot] PSPTool – Display, extract, and manipulate PSP firmware

[Christian Werling]

Hi everyone,

over the past year I did some research on AMD’s controversial Secure Processor (formerly known as Platform Security Processor or PSP). Its firmware is stored in an undocumented area of UEFI images and so I wrote a tool that can parse it. I thought some of you might be interested in that: https://github.com/cwerling/psptool https://github.com/cwerling/psptool

It is accompanied by PSPTrace, which can correlate an SPI capture of a boot procedure to the AMD firmware entries so you can deduct some boot logic from it.

Cheers,
Christian
