From 9d57e61bf72336e13e4cd3c31e93ab26266296a8 Mon Sep 17 00:00:00 2001 From: Leonardo Bras Date: Thu, 15 Apr 2021 15:00:51 -0300 Subject: of/pci: Add IORESOURCE_MEM_64 to resource flags for 64-bit memory addresses Many other resource flag parsers already add this flag when the input has bits 24 & 25 set, so update this one to do the same. Some devices (like virtio-net) have more than one memory resource (like MMIO32 and MMIO64) and without this flag it would be needed to verify the address range to know which one is which.
