Merge tag 'highbank-debugll-cleanup' of git://sources.calxeda.com/kernel/linux into next/soc
From Rob Herring: Use common debug_ll_init function and remove the static mapping code from mach-highbank. * tag 'highbank-debugll-cleanup' of git://sources.calxeda.com/kernel/linux: ARM: highbank: use common debug_ll_io_init ARM: implement debug_ll_io_init()
