[PATCH 0/3] MIPS: allow keeping the dtb command line

[Jonas Gorski <jogo@openwrt.org>]

Currently MIPS kernel code overwrites any bootargs from devicetree
unconditionally with the arcscmdline. Several targets work around this
by copying the devicetree bootargs into the arcscmdline after parsing
the device tree.

This patchset adds a new kernel option for keeping the devicetree
bootargs, then removes the workarounds and lets the targets instead make
use of that option.

Since some targets use OF but don't make use of the devicetree bootargs,
treat them like non-OF enabled targets and only use the prom commandline/

Jonas Gorski (3):
  MIPS: use USE_OF as the guard for appended dtb
  MIPS: make the kernel arguments from dtb available
  MIPS: make MIPS_CMDLINE_DTB default
