Author: hailfinger Date: Sat Jul 17 14:54:09 2010 New Revision: 1085 URL: http://flashrom.org/trac/coreboot/changeset/1085 Log: Change the SPI bitbanging core to fix a subtle bug (which had no effect so far) and to make integration of the RayeR SPIPGM and Nvidia MCP6x/MCP7x SPI patches easier. Kill a few global variables and require explicit initialization of bitbanging delay. A big thank you to Johannes Sjölund for testing an earlier version of the code as part of the Nvidia MCP6x/MCP7x SPI bitbanging patch.

USB - PIO based flasher
by Joseph Smith 15 Jul '10

15 Jul '10

Hello, Has anyone noticed this product? http://www.bmc-messsysteme.de/us/pr-usb-pio.html I think this would make an awesome little flasher :-) And it already supports many OS's: Windows® 7/XP as well as under MAC OS X, Free BSD and Linux -- Thanks, Joseph Smith Set-Top-Linux www.settoplinux.org

[PATCH] Allow bus override with forced read
by Carl-Daniel Hailfinger 15 Jul '10

15 Jul '10

If someone wants to perform a forced read of a chip via mmap, we should allow that even if the host doesn't support the bus this chip needs. Example: flashrom -p dummy:bus=spi -V -c Am29F016D -f -r foo.rom This won't work right now because -f won't override probe skipping. So far the only use of this bus override is for the internal programmer, and as such I wonder whether we should make the bus override conditional on the internal programmer. It's pointless for other programmers anyway. Comments welcome.

[PATCH] Hook up SPI unlock to infrastructure
by Carl-Daniel Hailfinger 14 Jul '10

14 Jul '10

We have a generic unlocking infrastructure, but all SPI chips ignored it. Fix it. Actually check if the unlock worked instead of just assuming it worked. This depends on [PATCH] Convert SPI chips to partial write.
