From 021ee9a6da1cfc57f6a6c769c3c898bdd4753108 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 18 Dec 2007 16:33:06 +0900 Subject: libata: reimplement ata_acpi_cbl_80wire() using ata_acpi_gtm_xfermask() Reimplement ata_acpi_cbl_80wire() using ata_acpi_gtm_xfermask() and while at it relocate the function below ata_acpi_gtm_xfermask(). New ata_acpi_cbl_80wire() implementation takes @gtm, in both pata_via and pata_amd, use the initial GTM value. Both are trying to peek initial BIOS configuration, so using initial caching value makes sense. This fixes ACPI part of cable detection in pata_amd which previously always returned 0 because configuring PIO0 during reset clears DMA configuration.
