Message:

make ppc32 OFW usage on par with sparc64, make appropriate modifications elsewhere

  • introduce ofw_tree_walk_by_device_type() to gather all OFW devices of a given type
  • ppc32 uses canonized OFW tree, mac-io and display devices are detected in kernel (not by the boot loader) by means of device type
  • various busses (PCI, EBUS, etc.) stay sparc64 specific for now
  • boot memcpy() is defined in a common way
  • BALLOC_MAX_SIZE is platform-dependent
  • ppc32 and sparc64 boot loaders cleanup (removal of obsolete stuff, data is not passed by global variables if not necessary, etc.)
  • balloc and OFW tree canonizer have now a provision to support different mapping of the data during boot time and kernel run-time
  • OFW tree canonizer uses balloc_rebase() to store pointers suitable for access during kernel run-time (with potentially different memory mapping than during boot time)
