From: David Daney <david.daney@xxxxxxxxxx> The new Enhanced Allocation (EA) capability support (patches to follow) creates resources with the IORESOURCE_PCI_FIXED set. Since these resources cannot be relocated or resized, their alignment is not really defined, and it is therefore not specified. This causes a problem in pbus_size_mem() where resources with unspecified alignment are disabled. So, in pbus_size_mem() skip IORESOURCE_PCI_FIXED resources, instead of disabling them.
