Unused functions...
by Carl-Daniel Hailfinger 27 Mar '10

27 Mar '10

We have a few unused functions in our codebase. Should we - mark then static (may cause gcc to complain if -Wunused-function is enabled) - put them inside #if 0 (code will bitrot) - remove them from the source base entirely (some may be used in the future) jedec.c: data_polling_jedec (maybe some chip in the future won't support toggle_jedec) stm50flw0x0x.c: erase_sector_stm50flw0x0x (keep?) m29f400bt.c: write_m29f400bt (hm, probably kill) 82802ab.c: erase_82802ab (kill, old-style erase) pm49fl00x.c: lock_49fl00x (for the future) sst49lfxxxc.c: unlock_block_49lfxxxc (strange, don't we use that?) spi.c: default_spi_send_command (if one chip driver ever supports only multicommand) spi25.c: spi_write_status_enable (we should use it, some chips require that) spi_write_disable (does that make sense?) spi_aai_write (need some write infrastructure changes for this) spi_chip_erase_d8 (kill) flashrom.c: chip_writel (will we ever need it?) chip_writen (this one might be usable for a few chip drivers) chip_readl (will we ever need it?) list_programmers (no idea) register_shutdown (needed for ECs) need_erase (needed for partial write) internal.c: pci_dev_find_filter (hmmm) Regards, Carl-Daniel -- http://www.hailfinger.org/

Include detailed versioning information in the binary (--version). Signed-off-by: Idwer Vollering <vidwer(a)gmail.com> --- Future thoughts: include the used version of libpci.

27 Mar '10

Author: hailfinger Date: Sat Mar 27 17:36:40 2010 New Revision: 987 URL: http://flashrom.org/trac/coreboot/changeset/987 Log: Add runtime and build environment info to the flashrom version message. This patch uses code from Idwer Vollering and Maciej Pijanka. I've added Makefile support and compiler version printing and restructured the code heavily. The code prints runtime system information and buildtime libpci information (I couldn't find any runtime libpci version function). Due to our ability to cross-compile flashrom, buildtime system information from "uname -mrs" doesn't help diagnosing any problems. That's why only libpci and gcc are buildtime info, and the rest is runtime info.

[PATCH] Clean up delay loop calibration
by Carl-Daniel Hailfinger 27 Mar '10

27 Mar '10

Note: This patch is the first step towards a better delay loop calibration which will work regardless of how smart the C compiler is.

GIGABYTE - GA-8IPE1000MK - ERASE FAILED!
by af＠localmta.zone4web.com 27 Mar '10

27 Mar '10

Hello, First - Great tool - Great job - Thanks ! Please excuse my _great_ english. Atleast it should be understandable enough. Here is my problem: I'm trying to update the bios of GA-8IPE1000MK board from GIGABYTE. Here is the output of flashrom which explains the problem: --------------> # flashrom -w pe1000mk.f14 flashrom v0.9.1-r710 No coreboot table found. Found chipset "Intel ICH5/ICH5R", enabling flash write... OK. This chipset supports the following protocols: Non-SPI. Calibrating delay loop... OK. Found chip "SST SST49LF002A/B" (256 KB, FWH) at physical address 0xfffc0000. Flash image seems to be a legacy BIOS. Disabling checks. Writing flash chip... ERASE FAILED at 0x00000000! Expected=0xff, Read=0x25, failed byte count from 0x00000000-0x00003fff: 0x3fb6 ERASE FAILED! ERASE FAILED! ERASE FAILED! ERASE FAILED! FAILED! Your flash chip is in an unknown state. Get help on IRC at irc.freenode.net channel #flashrom or mail flashrom(a)flashrom.org ------------------------------------------------------------ DO NOT REBOOT OR POWEROFF! <----------------- After that I verified if flashrom actually changed something. I have a backup of the original bios and used it for the verify procedure. Rebooted and everything works normal with the old bios. Here is a link to bios update: http://download.gigabyte.eu/FileList/BIOS/motherboard_bios_ga-8ipe1000mk_f1… The .exe file can be extracted under linux with p7zip. I'm attaching the output of 'flashrom -V', 'lspci -nnvvvxxx', 'superiotool -deV' I hope this information is something to start. Thanks for your time!

Re: [flashrom] [PATCH] [DEMO] Merge print/print_wiki tables

I'm not exactly thrilled about this patch (not your fault). Yes, it reduces a sizable amount of duplication. Yes, it reduces the amount of consistency checking we have to do. Yes, it will probably reduce the number of mismatch bugs each time someone adds a new board. Still, the original reason I didn't want URLs and board names in the same master table is that I personally think URLs are ugly and should not be in flashrom at all. print_wiki.c allowed me to ignore that stuff without having to sacrifice working on any board lists. I can just pretend print_wiki doesn't exist and be happy. ;-) I won't veto the patch for two reasons: 1. You create most board enables and add most supported boards nowadays, so this is much more "your" turf than mine, and it should be in a state that makes development easier for you. 2. Uwe created most of the printing (and IIRC all of the wiki) code, so he will know if this patch is a good idea or not. If Uwe acks this, go ahead. Regards, Carl-Daniel -- http://www.hailfinger.org/

The only thing that happens is reordering, but AFAICS this won't affect output in any way. Does ordering into different (OK/boardenable/bad) groups even make sense? That stuff is bound to change anyway we fix/modify some boards, and the group info is stored in other arrays anyway. A similar question applies to the laptop/non-laptop distinction in that table. Your patch changes the code to match the comments again, so I don't have a valid code-based reason to reject your patch. Still, I think we should discuss the general ordering of that table before that file will get a hotbed of reodering moves.
