commit e83bf69e7a3ba8e1dd7e438781d16af73adff0cf Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Aug 27 20:00:33 2012 +0300
Fix AMD UMA for RS780
In commit 6b5eb1cc2d1702ff10cd02249d3d861c094f9118 setup of UMA memory region was moved to happen at a later state and this broke UMA with RS780 southbridge.
Share the TOP_MEM and UMA settings before any of the PCI or CPU scanning takes place.
