charset=UTF-8 Content-Transfer-Encoding: 8bit Add macros for declaring static binary attributes for Alpha's PCI resource files: - pci_dev_resource_attr(), for dense/BWX systems (mmap dense) - pci_dev_resource_sparse_attr(), for sparse systems (mmap sparse) - pci_dev_resource_dense_attr(), for dense companion files (mmap dense) Each macro creates a const bin_attribute with the BAR index stored in the .private property and the appropriate .mmap callback.
