Re: [PATCH v2 0/2] PCI: Add support for PCI Enhanced Allocation "BARs"

PCI Enhanced Allocation is a new method of allocating MMIO & IO
resources for PCI devices & bridges. It can be used instead
of the traditional PCI method of using BARs.

EA entries are hardware-initialized to a fixed address.
Unlike BARs, regions described by EA are cannot be moved.
Because of this, only devices which are permanently connected to
the PCI bus can use EA. A removable PCI card must not use EA.

As it is fixed, can you put IORESOURCE_PCI_FIXED in the res->flags?
