+# For TEST_TYPE = config_bisect
+#
+#  In those cases that you have two different configs. One of them
+#  work, the other does not, and you do not know what config causes
+#  the problem.
+#  The TEST_TYPE config_bisect will bisect the bad config looking for
+#  what config causes the failure.
+#
+#  The way it works is this:
+#
+#   First it finds a config to work with. Since a different version, or
+#   MIN_CONFIG may cause different dependecies, it must run through this
+#   preparation.
+#
+#   Overwrites any config set in the bad config with a config set in
+#   either the MIN_CONFIG or ADD_CONFIG. Thus, make sure these configs
+#   are minimal and do not disable configs you want to test:
+#   (ie.  # CONFIG_FOO is not set).
+#
+#   An oldconfig is run on the bad config and any new config that
+#   appears will be added to the configs to test.
+#
+#   Finally, it generates a config with the above result and runs it
+#   again through make oldconfig to produce a config that should be
+#   satisfied by kconfig.
+#
+#   Then it starts the bisect.
+#
+#   The configs to test are cut in half. If all the configs in this
+#   half depend on a config in the other half, then the other half
+#   is tested instead. If no configs are enabled by either half, then
+#   this means a circular dependency exists and the test fails.
+#
+#   A config is created with the test half, and the bisect test is run.
+#
+#   If the bisect succeeds, then all configs in the generated config
+#   are removed from the configs to test and added to the configs that
+#   will be enabled for all builds (they will be enabled, but not be part
+#   of the configs to examine).
+#
+#   If the bisect fails, then all test configs that were not enabled by
+#   the config file are removed from the test. These configs will not
+#   be enabled in future tests. Since current config failed, we consider
+#   this to be a subset of the config that we started with.
+#
+#   When we are down to one config, it is considered the bad config.
+#
+#   Note, the config chosen may not be the true bad config. Due to
+#   dependencies and selections of the kbuild system, mulitple
+#   configs may be needed to cause a failure. If you disable the
+#   config that was found and restart the test, if the test fails
+#   again, it is recommended to rerun the config_bisect with a new
+#   bad config without the found config enabled.
+#
+#  The option BUILD_TYPE will be ignored.
+#
+#  CONFIG_BISECT_TYPE is the type of test to perform:
+#	build	- bad fails to build
+#	boot	- bad builds but fails to boot
+#	test	- bad boots but fails a test
+#
+#   CONFIG_BISECT is the config that failed to boot
+#
+# Example:
+#   TEST_START
+#   TEST_TYPE = config_bisect
+#   CONFIG_BISECT_TYPE = build
+#   CONFIG_BISECT = /home/test/¢onfig-bad
+#   MIN_CONFIG = /home/test/config-min
