This had major conflicts in the above files.

I've fixed it up but please check I did it correctly:

  https://github.com/mpe/powerpc-merge/commits/pw/neelesh-i2c

It also doesn't build as a module:

  $ grep CONFIG_I2C_OPAL .config
  CONFIG_I2C_OPAL=m
  $ make ...
  ...
  ERROR: "opal_i2c_request" [drivers/i2c/busses/i2c-opal.ko] undefined!
