Subject: [PATCH v2 0/7] Improve boot command line handling

The purpose of this series is to improve and enhance the
handling of kernel boot arguments.

It is first focussed on powerpc but also extends the capability
for other arches.

This is based on suggestion from Daniel Walker <danielwa@...co.com>

Christophe Leroy (7):
  cmdline: Add generic function to build command line.
  drivers: of: use cmdline building function
  powerpc: convert to generic builtin command line
  cmdline: Add capability to prepend the command line
  powerpc: add capability to prepend default command line
  cmdline: Gives architectures opportunity to use generically defined
    boot cmdline manipulation
  powerpc: use generic CMDLINE manipulations
