    powerpc: Run on old powermacs. · a575b807
    Paul Mackerras authored
    Old powermacs have a number of differences from current machines:
    - there is no interrupt tree in the device tree, just interrupt
      or AAPL,interrupt properties
    - the chosen node in the device tree is called /chosen@0
    - the OF claim method doesn't map the memory, so we have to do
      an explicit map call as well
    - there is no /chosen/cpu property on SMP machines
    - the NVRAM isn't structured as a set of partitions.
    This adapts the merged powermac support code to cope with these
