From 8e4e45185f2db2b1b0fc4b465d80682a1c6789a7 Mon Sep 17 00:00:00 2001 From: hailfinger Date: Mon, 28 Feb 2011 23:58:15 +0000 Subject: Update the ITE IT8500 EC support to match the current state of the flashrom-chromium tree. This code has been deployed and tested to work on the Cr-48. There are a few caveats, though: - The boot BIOS straps register must be modified to select LPC. This can be done with the "select_bbs.sh" script (Install iotools at http://code.google.com/p/iotools/ before using select_bbs). - It is very important to disable power management daemons before running flashrom on this EC. I commented out the brute force method we use in the Chromium OS branch that disables powerd, since IIRC Carl-Daniel has a better approach in the works. - Due to dependencies which may be introduced by the OEM/ODM EC firmware, the code is not guaranteed to work for anything other than the Cr-48. Signed-off-by: David Hendricks Carl-Daniel comments: Code is not hooked up yet because probing needs to be sorted out.
