Bjorn,
A small snafu...

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.

Should be:
r->flags & IORESOURCE_PCI_FIXED
With the erroneous '|', sizing of bridge resources can break.
Q: How to fix this.
A) Replace this patch entirely?
B) A patch on top of this one?
