Author: hailfinger Date: 2009-08-19 15:55:34 +0200 (Wed, 19 Aug 2009) New Revision: 692 Modified: trunk/flashrom.c Log: Disallow erase/write for known bad chips so people won't try without a clear understanding. Allow override with --force. If write/erase failed, warn the user to get help and not shutdown/reboot the computer. Warn that the result of a forced read is often garbage. Too many users believed that a forced read meant that everything was fine. Wait 1 second between erase and verify. This fixes a few reports where verify directly after erase had unpleasant side effects like corrupting flash or at least getting incorrect verify results.

[PATCH] Compile out FT2232 SPI if not selected
by Carl-Daniel Hailfinger 19 Aug '09

19 Aug '09

If FT2232H SPI is not enabled, it should be compiled out completely. We can't remove ft2232_spi.o from unconditional OBJS yet due to our makefile structure (make features), but this patch adds #ifdefs around all FT2232H code, so the net effect is the same.

19 Aug '09

flashrom 0.9.1-rc1 has been released. Draft 0.9.1 announcement is at http://www.coreboot.org/Flashrom/0.9.1 and will be moved to flashrom.org once the release is out. http://patchwork.coreboot.org/project/flashrom/list/ has all pending flashrom patches. The following are 0.9.1 material and need an Ack right now: Tidy up docs before release Add serprog to man page quick shot at BSD RDMSR support Compile out FT2232 SPI if not selected Improve error messages, protect the user A tarball will show up at http://qa.coreboot.org/releases/ soon.
