[PATCH v13 09/16] powerpc/PCI: Keep resource idx order with bridge register number

Show all headers | View raw

Same as sparc version.

Make resource with consistent sequence
like other arch or directly from pci_read_bridge_bases(),
even when non-pref mmio is missing, or out of ordering in firmware reporting.

Just hold i = 1 for non pref mmio, and i = 2 for pref mmio.
