From 8ac2b42a45896641ed292deaf038a1d2703d85a6 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 1 Feb 2008 23:09:30 +0100 Subject: ide: add IDE_HFLAG_CLEAR_SIMPLEX host flag * Rename 'simplex_stat' variable to 'dma_stat' in ide_get_or_set_dma_base(). * Factor out code for forcing host out of "simplex" mode from ide_get_or_set_dma_base() to ide_pci_clear_simplex() helper. * Add IDE_HFLAG_CLEAR_SIMPLEX host flag and set it in alim15x3 (for M5229), amd74xx (for AMD 7409), cmd64x (for CMD643), generic (for Netcell) and serverworks (for CSB5) host drivers. * Make ide_get_or_set_dma_base() test for IDE_HFLAG_CLEAR_SIMPLEX host flag instead of checking dev->device (BTW the code was buggy because it didn't check for dev->vendor, luckily none of these PCI Device IDs was used by some other vendor for PCI IDE controller).
