From 938174e59f83354251a75a2b90171e0ffdf6f1d7 Mon Sep 17 00:00:00 2001 From: "Sean O. Stalley" Date: Thu, 29 Oct 2015 17:35:39 -0500 Subject: PCI: Add support for Enhanced Allocation devices Add support for devices using Enhanced Allocation entries instead of BARs. This allows the kernel to parse the EA Extended Capability structure in PCI config space and claim the BAR-equivalent resources. See https://pcisig.com/sites/default/files/specification_documents/ECN_Enhanced_Allocation_23_Oct_2014_Final.pdf [bhelgaas: add spec URL, s/pci_ea_set_flags/pci_ea_flags/, consolidate declarations, print unknown property in hex to match spec] Signed-off-by: Sean O.
