    powerpc/eeh: Dump PE location code · 357b2f3d
    Gavin Shan authored
    As Ben suggested, it's meaningful to dump PE's location code
    for site engineers when hitting EEH errors. The patch introduces
    function eeh_pe_loc_get() to retireve the location code from
    dev-tree so that we can output it when hitting EEH errors.
    
    If primary PE bus is root bus, the PHB's dev-node would be tried
    prior to root port's dev-node. Otherwise, the upstream bridge's
    dev-node of the primary PE bus will be check for the location code
    directly.
