Yeah, we can handle it well because pcibios_window_alignment() affects
both starting address and size of PCI bridge window. More details could
be found in pci/drivers/setup-bus.c::pbus_size_mem(): starting address,
"size0", "size1", "size1-size0" are aligned to "min_align", which is
coming from pcibios_window_alignment() (16MB as mentioned).
Thanks,
Gavin
