From c87deff776feacd05a7411097e8c8c57e549e638 Mon Sep 17 00:00:00 2001 From: Hidetoshi Seto Date: Mon, 18 Dec 2006 10:31:06 +0900 Subject: PCI : Add selected_regions funcs This patch adds the following changes into generic PCI code especially for PCI legacy I/O port free drivers. - Added new pci_request_selected_regions() and pci_release_selected_regions() for PCI legacy I/O port free drivers in order to request/release only the selected regions. - Added helper routine pci_select_bars() which makes proper mask of BARs from the specified resource type. This would be very helpful for users of pci_enable_device_bars().
