- Remove explicit requirement that the SOC registers be found except as an optimization (although the MPC85XX LAW drivers still require they be found externally, which should change). - Remove magic CCSRBAR_VA value. - Allow bus_machdep.c's early-boot code to handle non 1:1 mappings and systems not in real-mode or global 1:1 maps in early boot. - Allow pmap_mapdev() on Book-E to reissue previous addresses if the area is already mapped. Additionally have it check all mappings, not just the CCSR area. This allows the console on e500 systems to actually work on systems where the boot loader was not kind enough to set up a 1:1 mapping before starting the kernel.
