[flashrom] A bunch of old parallel chips

I noticed a few chips that were not listed for all operations on the
flashrom supported hardware webpage:
- ASD AE29F2008, fake Winbond W29C020C found on a PCChips motherboard
full of fake/remarkered chips, it looks like it was reported previously
on the list, [0], [1],
- AMIC A29002T, [2],
- AMD Am27C010, not correctly detected, probe forced for Am29F010A/B
(same signals/timings for reading). Electrical erase is impossible
(UV-Light needed), programmation wasn't tried (this motherboard doesn't
supply the 12.5V needed for Vpp), [3],
- Macronix MX29F002T, [4],
- SST SST29EE10, [5],
Some chips (A29002T, MX29F002T) are already marked as OK on the
supported hardware page, but were probably not already tested in the
flashrom release I'm using.
I also have a Winbond W29EE11 which wasn't detected by flashrom and
seems pretty old and rare (I didn't manage to find the datasheet so I
assumed the voltages and the pinout were the same...).
From the bios sticker, it looks like it was from a socket 7 motherboard
from the years 96~97.
All these chips were tested on a MSI MS6147 Motherboard (Intel PIIX4 BX
chipset with a 32-pin DIL socket), using flashrom v0.9.2-r1141 (Debian
Squeeze).
Thanks,
