Compare the RAM capacity in the running board revision with the factory revision in OTP row 32. Report possible RAM tampering or replacement and advise contacting the seller to arrange a return.

Return distinct statuses for matching, mismatched, and unavailable capacity information. Explain that matching capacity cannot establish that the RAM is original.

A helpful tool for users to ensure that their RAM hasn't been tampered with.

The comparison logic was ported from #924 but has been split out into a separate auditing tool to address this review:

We aren't going to put time or effort into devices which have been miss-sold.

This PR completely removes all code designed to support miss-sold devices and is instead designed only to authenticate the RAM is genuine(as much as is technically feasible at least). This should make it easier for customers to ensure that they only purchase non-tampered hardware.

Whist I can see the motivation for the tool, the answer is still no for including any such tool as part of this package. If the user encounters an issue with the PI then they should contact the original seller..

Would it make sense as part of this package or some other package?

The issue is, without something like this how would the user know they need to contact the original seller and not a different support channel/forum? If raspberry pi wants to ensure the market doesn't have tampered ram raspberry pi's doesn't it make sense to make it as easy as possible for a user to detect such hardware? Isn't it in raspberry pi's interest to ensure users can easily detect ram tampering so that they know to go after the original sellers who are selling the tampered hardware so that they don't otherwise think raspberry pi hardware is just unreliable or something?

For example if I'm using this raspberry pi hardware for building a commercial product how can I do my due diligence to prevent tampered raspberry pi hardware from ending up as part of my product? This is especially important for cases where the business costs of having hardware fail in the field due to tampered RAM might be high.

Sorry, this isn't something that I can help with. If people use an authorised reseller then they will not encounter these parts and they will all support RMAs for faulty products.

Closing - modified boards deliberate or not sold as advertise are outside the scope of this repo.
