commit e54588e6bec6bc989a06b305e5e85387aeddea7f Author: Mike Loptien mike.loptien@se-eng.com Date: Fri Jun 6 15:21:28 2014 -0600
Persimmon: Change MPTable to use mainboard IRQ routing
With the addition of the mainboard PCI IRQ routing tables for AMD Persimmon, the MPTables can be set to use this information to accurately reflect the real hardware settings of the system. Additionally, the IOAPIC gets defined before the MPTable gets generated so the settings can be read directly from the IOAPIC registers instead of 'guessing' at them as was done before.
