| Subject: ahci: Enable SB600 64bit DMA on Asus M3A |
| |
| From: Mark Nelson <mdnelson8@gmail.com> |
| |
| commit 3c4aa91f21f65b7b40bdfb015eacbcb8453ccae2 upstream. |
| |
| Like e65cc194f7628ecaa02462f22f42fb09b50dcd49 this patch enables 64bit DMA |
| for the AHCI SATA controller of a board that has the SB600 southbridge. In |
| this case though we're enabling 64bit DMA for the Asus M3A motherboard. It |
| is a new enough board that all of the BIOS releases since the initial |
| release (0301 from 2007-10-22) work correctly with 64bit DMA enabled. |
