From aad4564498dcb0aad769a79e5e2aa9a661dfb51f Mon Sep 17 00:00:00 2001 From: Kjetil Oftedal Date: Wed, 19 Oct 2011 16:20:50 -0700 Subject: [PATCH] sparc: Add alignment flag to PCI expansion resources Currently no type of alignment is specified for PCI expansion roms while parsing the openfirmware tree. This causes calls to pci_map_rom() to fail. IORESOURCE_SIZEALIGN is the default alignment used for rom resouces in pci/probe.c, and has been verified to work with various cards on a ultra 10.
