I'd still like to know:

JEDEC probing
I don't believe we will be able to test this anytime soon because the chip is quite old.
And it is listed as TEST_OK_PREW in flashchips.c, so we have some tester somewhere (Uwe). By the way, since we don't probe for that chip anymore, we have to change the chip to TEST_OK_REW|TEST_BAD_PROBE.
- whether we can write 0xFF to the chip after probing, triggering a
reset for most chips.
We did try writing the product ID exit command, and unfortunately it did not help.
Yes, that's why I suggested 0xFF.
Note that the chip still responds fine to LPC reads, data is returned, but any write commands are ignored. The way I read the data sheet this indicates that the chip is in an undocumented state.
Please do feel free to investigate this further, but personally I doubt we'll ever find out what AMIC's state machine is up to. :\
Unfortunately I don't have the necessary hardware.
