Carl asked me to double check as many as i could. Sorry for the somewhat funny
notation, but it helped me keep track of where i was. There are only a few not
mentioned.. i worked that out with Sean on IRC.
Also, major sorry for the delay.. this was a little tougher than i expected.
The features quoted are the features i have checked. Comments are above.
Legend:
(C) = Checks out
(W) = Warning, sheet says otherwise.
(U) = Unsure, please double check and comment.
(N) = No datasheet available.
(S) = Skipped in this review because $REASON
[AMD Section]
(W)(U) I can't find evidence of anything other than write_jedec_1 in the
sheet. Please verify.
.name = "Am29F010A/B",
.feature_bits = FEATURE_ADDR_2AA|FEATURE_EITHER_RESET,
.write = write_jedec,
(W)(U) Uhm, the N versions do not support reset at all, but I don't think we
can tell them apart with out a runtime test. Also they are ADDR_2AA I think.
.name = "Am29F002(N)BB" / "Am29F002(N)BT"
.feature_bits = FEATURE_SHORT_RESET,
.write = write_jedec_1,
(C) No comments.

.name = "Am29LV040B",
.feature_bits = FEATURE_ADDR_2AA|FEATURE_SHORT_RESET,
.write = write_jedec_1,
(C) Strictly speaking it doesn't need ADDR_2AA as it has "Don't care" for all
addresses (except the last in ID detection) [weird freakin' chip!, red]
.name = "Am29LV081B",
.feature_bits = FEATURE_ADDR_2AA|FEATURE_SHORT_RESET,

registermap.

(U) Generally i have a hard time with ST and write_jedec vs write_jedec_1,
so someone else should look over this...
