From: Bjorn Helgaas Date: Mon, 28 Nov 2016 23:21:02 +0000 (-0600) Subject: PCI: Decouple IORESOURCE_ROM_ENABLE and PCI_ROM_ADDRESS_ENABLE X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7a6d312b50e63f598f5b5914c4fd21878ac2b595;p=linux-beck.git PCI: Decouple IORESOURCE_ROM_ENABLE and PCI_ROM_ADDRESS_ENABLE Remove the assumption that IORESOURCE_ROM_ENABLE == PCI_ROM_ADDRESS_ENABLE. PCI_ROM_ADDRESS_ENABLE is the ROM enable bit defined by the PCI spec, so if we're reading or writing a BAR register value, that's what we should use. IORESOURCE_ROM_ENABLE is a corresponding bit in struct resource flags.
