From 57c802e84f9c759c3d1794a9dbe81bc10444df62 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 26 Jan 2008 20:13:05 +0100 Subject: ide: add ide_init_port_hw() helper * Add ide_init_port_hw() helper. * rapide.c: convert rapide_locate_hwif() to rapide_setup_ports() and use ide_init_port_hw(). * ide_platform.c: convert plat_ide_locate_hwif() to plat_ide_setup_ports() and use ide_init_port_hw(). * sgiioc4.c: use ide_init_port_hw(). * pmac.c: add 'hw_regs_t *hw' argument to pmac_ide_setup_device(), setup 'hw' in pmac_ide_{macio,pci}_attach() and use ide_init_port_hw() in pmac_ide_setup_device(). This patch is a preparation for the future changes in the IDE probing code. There should be no functionality changes caused by this patch.
