Add support for more than one Super I/O or EC per machine
Flashrom currently only supports exactly one Super I/O or Embedded Controller, and this means quite a few notebooks and a small subset of desktop/server boards cannot be handled reliably and easily. Allow detection and initialization of up to 3 Super I/O and/or EC chips. WARNING! If a Super I/O or EC responds on multiple ports (0x2e and 0x4e), the code will do the wrong thing (namely, initialize the hardware twice). I have no idea if we should handle such situations, and whether we should ignore the second chip with identical ID or not. Initializing the hardware twice for the IT87* family is _not_ a problem, but I don't know how well IT85* can handle it (and whether IT85* would listen at more than one port anyway). Corresponding to flashrom svn r1289. Signed-off-by: Carl-Daniel Hailfinger <> Thanks to Thomas Schneider for testing on a board with ITE IT87* SPI. Test report (success) is here: Thanks to David Hendricks for testing on a Google Cr-48 laptop with ITE IT85* EC SPI. Test report (success) is here: Acked-by: David Hendricks <>
