      powerpc/powernv: Remove OPAL v1 takeover · e2500be2
      Michael Ellerman authored
      In commit 27f44888 "Add OPAL takeover from PowerVM" we added support
      for "takeover" on OPAL v1 machines.
      
      This was a mode of operation where we would boot under pHyp, and query
      for the presence of OPAL. If detected we would then do a special
      sequence to take over the machine, and the kernel would end up running
      in hypervisor mode.
      
      OPAL v1 was never a supported product, and was never shipped outside
      IBM. As far as we know no one is still using it.
      
      Newer versions of OPAL do not use the takeover mechanism. Although the
      query for OPAL should be harmless on machines with newer OPAL, we have
      seen a machine where it causes a crash in Open Firmware.
      
      The code in early_init_devtree() to copy boot_command_line into cmd_line
      was added in commit 817c21ad
      
       "Get kernel command line accross OPAL
      takeover", and AFAIK is only used by takeover, so should also be
      removed.
