I have tagged all of the ones in this list Stefan gave me except the Sanyo
one (no datasheet- apparently not a new issue either).
If there are any questions or comments, please send them.

fixing the stuff that needs fixing, of course.<br>
<br>
steve said he might look into it, so this is what has to be done:<br>
i have attached a file containing what seems to be the spi chips<br>
without correctly set feature_bits fields. we need to check the<br>
datasheets for the opcodes needed to enable writing to the status<br>
register. normally this is either WREN (write enable) or EWSR (enable<br>
write status register), or both.<br>
currently we are only interested in the non-volatile bits of the status<br>
register, but there are chips that require another write enable command<br>
for the volatile bits. if anyone creates a spreadsheet, he should<br>
probably note those too if feasible or maybe even add a comment in the<br>
patch.<br>
<br>
the field should be added after page_size and either set to:<br>
.feature_bits = FEATURE_WRSR_EWSR<br>
or<br>
.feature_bits = FEATURE_WRSR_EITHER<br>
if EWSR and WREN are allowed (all other SPI chips are already set<br>
to FEATURE_WRSR_WREN). in the case we encounter a chip that does use<br>
something else a comment should suffice for the time being.<br>
<br>
we could also split the work up, if it takes too long otherwise...<br>
