      powerpc: Make coff boot wrapper load the kernel at 8M · 85e568ea
      Paul Mackerras authored
      Previously it claimed 7MB starting at the 9M point and loaded the
      kernel there.  That meant that prom_init put the flattened device
      tree above 16M.  On the 601 that caused the early device tree scan
      to fail, since only 16MB are mapped with BATs on the 601.  Moving
      this down to 8MB allows prom_init to put the flattened device tree
      between 15M and 16M, so it works on the 601.

      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
      issues.

      powerpc: Fix time code for 601 processors · 96c44507
      Paul Mackerras authored
      The 601 doesn't have the timebase register; instead it has an RTCL
      register that counts nanoseconds and wraps at 1000000000, and an
      RTCU register that counts seconds.  This makes the necessary changes
      for the merged time code to use the RTCL/U registers when the kernel
      is running on a 601.
