[Skiboot] [RFC 00/12] NX 842 PowerNV kernel driver

[Dan Streetman]

These are the patches to add support for the NX-842 coproc on PowerNV.

Of particular note, this exports the opal_xscom_read/write() functions,
and the powernv nx-842 driver checks some of the xscom registers for
coprocessor status and errors, with more error checking/handling to
be added later.  The question there is, should the xscom r/w be done
in skiboot, and remove any xscom r/w from the kernel driver?

Any other comments are welcome also.

Dan Streetman (12):
  export of_get_ibm_chip_id function
  export xscom read/write
  Add ICSWX instruction
  add software 842 decompression
  move nx-842.c to nx-842-pseries.c
  add NX-842 platform frontend driver
  add nx842 constraints
  add PowerNV platform NX-842 driver
  simplify pSeries nx842 driver
  remove LZO fallback from crypto 842
  rewrite crypto 842 to use nx842 constraints
  add crypto compression sefltest
