From 6dcceddff53ad309b91b61661ae7deab37f272ec Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Mon, 3 Dec 2012 16:17:40 -0600 Subject: x86 intel: Add Firmware Interface Table support Haswell CPUs require a FIT table in the firmware. This commit adds rudimentary support for a FIT table. The number of entries in the table is based on a configuration option. The code only generates a type 0 entry. A follow-on tool will need to be developed to populate the FIT entries as well as checksumming the table. Verified image has a FIT pointer and table when option is selected.
