[CAUTION: External Email] Dear Shekar, I hope that Dave and Amin (and other concerned people subscribed to a flashrom mailing list) will test the W25Q128FW and W25Q256.W parts as soon as possible and tell the results. Huge benefit of flashrom is that it is 100% open source (so much less likely to suffer from bad code quality and security issues), and flashrom supports the inexpensive programmers like CH341A which costs just $2. The commercial programmers are often expensive and have a proprietary closed source software, which is usually bloated, may have the security holes (sometimes the deliberate backdoors) and often are supported only by Windows OS, so they aren't an option for many people. Our goal is to ensure the flashrom's good function in as many use cases and for as many parts as possible - and hope that together, with your kind help, we will achieve it.

Since the newer parts are supported on most commercial programmers and we did not hear back from you, we thought you have been able to program the parts successfully and have been able to use these parts on the AMD board. These parts are already supported on the AMD reference boards with Renoir. Thanks.

To add a support for W25Q128FW and W25Q256FW to flashrom - hopefully would be enough to create the correct chip definitions in flashchips.c / flashchips.h files using the datasheets for W25Q128FW and W25Q256FW.

The part numbers mentioned below are old parts and the part numbers are incomplete. The part numbers I have mentioned are supported on the AMD Renoir reference boards, and in turn supports all the CPUs that AMD offers today. If you have further questions about support for AMD products, please contact Jason Hawken at AMD, Toronto. I am not sure if these are supported on Raspberry.

Hi Amin, Please note that the W25Q128FW is a 1.8V chip, while Raspberry PI IOs are 3.3V. For Dediprog, pass in the `voltage` parameter, e.g. `flashrom -p dediprog:voltage=1.8 -r foo.bin` Also, as Mike mentioned it will help if we know the version of flashrom which you are trying to use. Some distributions provide very old versions.
