# Configuration for Linux on MIPS.

# You can set TARGET_ARCH_VARIANT to use an arch version other
# than mips32r2-fp. Each value should correspond to a file named
# $(BUILD_COMBOS)/arch/<name>.mk which must contain
# makefile variable definitions similar to the preprocessor
# defines in build/core/combo/include/arch/<combo>/AndroidConfig.h. Their
# purpose is to allow module Android.mk files to selectively compile
# different versions of code based upon the funtionality and
# instructions available in a given architecture version.
#
# The blocks also define specific arch_variant_cflags, which
# include defines, and compiler settings for the given architecture
# version.
