Few days ago stefanct, gave me a bunch of datasheets for GigaDevice
chips, so I could get me way into flashrom.
Here is 2 pathces. One with GigaDevice chips support and one with a fix
to *PROBABLE* pastebug in AMIC A25LQ64 chip definition, which I found
earlier.
I never used mailing lists and not sure about mime64 attachments, so
archive with datasheets can be found here:
