33 This module is a port from FreeBSD 4.3-6.1 ATA driver (ata-dma.c, ata-chipset.c) by
34 Søren Schmidt, Copyright (c) 1998-2008
35
36 Changed defaulting-to-generic-PIO/DMA policy
37 Added PIO settings for VIA
38 Optimized VIA/AMD/nVidia init part
39 Optimized Promise TX2 init part
40 Optimized Intel init part
