From b5a1a9abe1a54ba40a9612001920f98bbdd0c56f Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Tue, 4 Jul 2006 16:46:44 +1000 Subject: [POWERPC] Use const qualifiers for prom parsing utilites The of_bus callbacks map and get_flags can be constified, as they don't alter the range or addr arguments. of_dump_addr and of_read_addr can also be constified.
