[PATCH] Annotate evil twins
by Carl-Daniel Hailfinger 22 Jul '10

22 Jul '10

Evil twins are chips with identical IDs and different/incompatible characteristics (e.g. eraseblock layout, write strategy or size). Annotate them so flashrom can tell the user that it's not a matter of simply picking one of the chips in a list of multiple chips found. This patch only touches the AMIC A25L40PT and A25L40PU. I'm fairly sure there are more evil twins, but those two were touched recently.

[RFC] Chip ID #defines
by Carl-Daniel Hailfinger 22 Jul '10

22 Jul '10

Parts of flashrom codebase are really old any nobody ever got around to cleaning them up. flashchips.h is one of those places with organic growth on top of historic cruft. Right now, most chip ID #defines have underscores somewhere in the first few characters of the name. For a sizable portion of flash chips this underscore does not make any sense if you look at the original chip name. My best guess is that someone originally thought that having a vendor name as part of the chip ID #define. For chips which have the vendor name as part of the chip name anyway this might make sense. A prominent example is SST_49LF080A. OTOH, stuff like W_25X10 is just really ugly. Besides that, grepping for those identifiers requires a lot of guesswork if you only know the chip name as printed on the chip. I am not sure if we really want to have underscores in random places in all those IDs. Nobody ever bothered to make those #defines look sane or consistent. Should we kill the underscore inside the chip name completely and instead use $VENDORNAME_$CHIPNAME for the #defines? IMHO that looks more natural and makes grepping easier. We'd still have to decide whether we should use the vendor name as it is used in $VENDOR_ID or a different form. For SST (and a few other manufacturers) this is not a problem because the vendor ID #define is SST_ID. However, for Winbond it gets a bit more difficult because we have WINBOND_ID and WINBOND_NEX_ID. W_25X10 would become either WINBOND_NEX_W25X10 or WINBOND_W25X10. I think the former variant makes it easier to visually cross-check if the vendor and chip ID combination makes sense. Sometimes multiple chips have the same ID. That's not a problem if the chips have identical characteristics and if they share one common entry in flashchips.c. We could add .alias_vendor and .alias_name fields (or any similar solution) to struct flashchip to accommodate chips where the vendor and chip name changed a few times in a way that can't be expressed easily with "oldname/newname". We also should definitely talk about evil twins. Those are chips with identical IDs but distinct/incompatible programming strategies. I sent a patch to mark some of them as evil twins, but we still have to decide if those evil twins should use the same #define for the ID or if they should use different #defines.

[PATCH] RayeR speedups, variable port
by Carl-Daniel Hailfinger 21 Jul '10

21 Jul '10

Speed up RayeR SPIPGM driver in flashrom by a factor of 2. Allow specification of an alternate base port with flashrom -p rayer_spi:lptport=0x278 Any port number is allowed as long as it is nonzero, below 65536 and a multiple of four. Untested, should work. Martin, this one should hopefully reach the speed of SPIPGM.exe for reads. I'll ask Idwer to provide a DOS binary for you.

[RFC] National Semiconductor DP83815 NIC patch
by Andrew Morgan 21 Jul '10

21 Jul '10

Hi, I have a couple of Netgear FA311 network cards, which have DP83815DVNG chips on board, and a space to mount a 32-pin boot ROM socket. Looking at the datasheet for the chip I have created this patch. The datasheet suggests that reads and writes must be done 32 bits at a time, and only at 32 bit offsets. This seems strange for chips which have an 8 bit data bus. I don't think this code is ready for inclusion in flashrom yet, but if anyone has a card with this chip and can test it out then give it a go. I'm pretty sure it won't just work though. It might even destroy your computer/house/planet. I can't test it yet because the cards don't have a 32pin socket mounted on them. If and when I can add one then I can do some tests. This is my first 'large' patch so let me know what I have got wrong. :) Signed-off-by: Andrew Morgan <ziltro(a)ziltro.com> -- Andrew.
