# This script merges configuration fragments for boards supported by the
# generic MIPS kernel. It checks each for requirements specified using
# formatted comments, and then calls merge_config.sh to merge those
# fragments which have no unmet requirements.
#
# An example of requirements in your board config fragment might be:
#
# # require CONFIG_CPU_MIPS32_R2=y
# # require CONFIG_CPU_LITTLE_ENDIAN=y
#
# This would mean that your board is only included in kernels which are
# configured for little endian MIPS32r2 CPUs, and not for example in kernels
# configured for 64 bit or big endian systems.
