Hello Xavier,

thanks for your report!
I have marked the flash chip as fully tested and will commit that later
together with other small changes.
That's a *really* old version of flashrom and testing with programmers
that do not support the full address space is quite risky (often the
errors happen exactly at such boundaries). However, I decided to mark
it anyway because I don't expect any better reports coming anytime soon
(or ever) because of the age of the chip and its apparent rareness.
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
