[PATCH 0/3] PCI: Convert maintaining FW-assigned BIOS BAR values to alist of temporary entries

[Myron Stowe]

In commit 58c84eda075 functionality was introduced that tries to reinstate
the original, FW-assigned, BAR addresses of a PCI device when normal
resource assignment attempts fail.  To keep track of the BIOS BAR
addresses, struct pci_dev was augmented with an array to hold the BAR
addresses of the PCI device: 'resource_size_t
fw_addr[DEVICE_COUNT_RESOURCE]'.

The reinstatement of BAR addresses is an uncommon event leaving the
'fw_addr' array unused normally.  As the use of struct pci_dev is so
prevalent, this seems wasteful.

This patch series introduces a stand alone data structure and
corresponding set of interfacing routines, converting the underlying
aspects of the existing maintanence scheme to a list of temporary BIOS
BAR value entries instead.
