From a2302c68d923537436b1114aa207787c1a31bd50 Mon Sep 17 00:00:00 2001 From: John Keller Date: Wed, 4 Oct 2006 16:49:52 -0500 Subject: Altix: Initial ACPI support - ROM shadowing. Support a shadowed ROM when running with an ACPI capable PROM. Define a new dev.resource flag IORESOURCE_ROM_BIOS_COPY to describe the case of a BIOS shadowed ROM, which can then be used to avoid pci_map_rom() making an unneeded call to pci_enable_rom().
