On AMD, the "PCH" is the LPC device on PCI 0:14.3. According to "PPR for
AMD Family 17h Model 18h B1. 55570-B1 Rev 3.16 - Apr 14, 2021."
available on
https://www.amd.com/en/support/tech-docs/processor-programming-reference-ppr-for-amd-family-17h-model-18h-revision-b1
the low byte at D14F3x008 (bus 0 device 14 function 3 offset 8) is the
RevisionID of this device.
Using 0:1F.0 to read the RID in `Chipset.detect_platform` is likely to
be a bug from commit 2691f50bae ("Detect PCH based on platform vendor
ID"), which introduced AMD support in this function. Fix this by using
`bus, dev, fun` to read `pch_rid`.

CHIPSEC: Platform Security Assessment Framework
CHIPSEC is a framework for analyzing the security of PC platforms including hardware, system firmware (BIOS/UEFI), and platform components. It includes a security test suite, tools for accessing various low level interfaces, and forensic capabilities. It can be run on Windows, Linux, Mac OS X and UEFI shell. Instructions for installing and using CHIPSEC can be found in the manual.
NOTE: This software is for security testing purposes. Use at your own risk. Read WARNING.txt before using.
First version of CHIPSEC was released in March 2014: Announcement at CanSecWest 2014
