AMD/agesa: Add functions for AMD PCI IRQ routing
Port the changes that were made in amd/cimx to amd/agesa as were done in: commit c93a75a5ab067f86104028b74d92fc54cb939cd5 Author: Mike Loptien mike.loptien@se-eng.com Date: Fri Jun 6 15:16:29 2014 -0600
AMD/CIMx: Add functions for AMD PCI IRQ routing
This change also moves the PCI INT functions to southbridge/amd so that they can be used by CIMX and AGESA. The amd/persimmon board is updated for this change.
