ST 95XXX chips

[Николай Николаев]

      Hello
My pull request has already been created that had occurred *several months*
previously. I added support for ST 95XXX chips . The following chipsets
have been successfully tested for read, erase and write operations: ST [
95080, 95160, 95320, 95640, 95128, 95256 ]. I would like to discuss a new
features.
Maybe someone in the community will spent a bit of time and review my pull
request. Don't worry about the conflicting files. The part of the code has
already been merged into effect.




*I'm open-minded and ready. *

      Hello,
Thanks for the PR (https://github.com/flashrom/flashrom/pull/84). I
actually started to review this a long time ago, but apparently never
finished :-/ My bad.

The patch has a few merge conflicts, lots of dead code, and makes
changes that appear unrelated to ST 95XXX support. Please resolve the
merge conflicts and clean up the patch, and send another PR. Or better
yet, send directly to review.coreboot.org which is where upstream
review happens:

      Hi 
Would be able to help with m95640.
Thanks

      I was looking for a lot of time of a method to read the dump from a 95320 chip installed
on a Alfa Romeo radio in order to get the code, using the tools i had at home: Raspberry
PI and a Pomona SOIC8 clip.

I have tried multiple random Python scripts written by different people but none of them
have worked.

I did a bit of research and found this ,,unofficial" patch that seemed to support the
95XXX Chips, even if on the Flashrom.org page this is not listed.

Nikolay sent me all the informations i needed and i managed to both read and write my
95320 chip without any error or problem.

The wiring was done this way:

1 (CS) -> Pin 24 on Raspberry.
2 (SO/MISO) -> Pin 21
3, 7, 8 (3,3V + WP + HOLD) -> Pin 17 (i just used a breadboard here)
4 (GND) -> Pin 25
5 (SI/MOSI) -> Pin 19
6 (SCLK) -> Pin 23.

Commands used: 

read example command
./flashrom -cM95320 -f -V -p linux_spi:dev=/dev/spidev0.0,spispeed=5000 -r
random.M95080.8K.bin

write example command
./flashrom -cM95320 -f -V -p linux_spi:dev=/dev/spidev0.0,spispeed=5000 -w
random.M95M02.256K.bin

I really appreciate your work and you made me save some good money by avoiding buying a
programmer that reads 95XXX chips and use it just a single time.

Have a nice day!
