[PATCH] superiotool: ITE IT8661 enter_conf_mode working
by Urja Rannikko 20 Oct '08

20 Oct '08

Hello, This patch adds a special test+enable conf mode function for the IT8661 (and IT8770F which seems to be identical (same ID), thus the added "/IT8770F") which is called in the beginning of enter_conf_mode_ite (and if it succeeds, skip other enables). 0x3F0 is added to the ITE scanned ports because the 8661/8770 can be programmed to 0x3F0,0x370 or 0x3BD only (gets programmed by the test function). Signed-off-by: Urja Rannikko <urjaman(a)gmail.com> Also included is an proprietary bios dump from the board (with this patch) (that has an IT8770F). -- urjaman

[patch 0/7] Libpayload Updates
by jordan.crouse＠amd.com 20 Oct '08

20 Oct '08

I had occasion to use libpayload in an internal diagnostic this week, and I was able to find lots of room for improvement in libpayload.. :) Perhaps the biggest improvement here is the multiboot patch which lets libpayload applications run under GRUB unmolested. I think thats pretty cool, and it extends the reach of libpayload beyond coreboot. Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc.
