# Target configuration options. NOTE - target configurations will

# Target configs come in groups of three parameters. The first is the
# kernel configuration, the second is the architecture configuration,
# and the third is the machine configuration. You may pass in as
# many groups of configurations as you wish. Each item passed in is
# seperated by whitespace.
#
# Example:
# TARGET_CONFIGS="release ppc default debug i386 default release arm MX31ADS"
# Parameters may be in upper or lower case (they are converted to upper).
#
# "default" parameter is a special case. It means use the default value for
# that parameter. Here are the default values for each configuration:
#
# default kernel configuration = DEFAULT_KERNEL_CONFIG
# default architecture configuration = system architecture where you are running make.
# default machine configuration for ppc = none at this time.
# default machine configuration for i386 = none at this time.
# default machine configuration for arm = "S5L8900XRB".
