# Config.in.legacy - support for backward compatibility
#
# When an existing Config.in symbol is removed, it should be added again in this
# file, and take appropriate action to approximate backward compatibility. If
# there is an equivalent (set of) new symbols, these can just be select'ed by
# the old symbol. This makes sure that running 'make oldconfig' will make things
# "just work" when upgrading to a new buildroot version. If the change is too
# fundamental and cannot be fixed by a simple select, then the old symbol should
# select BR2_LEGACY.  If that symbol is set, the build will issue an error.
#
# When adding legacy symbols to this file, add them to the front. The oldest
# symbols will be removed again after about two years.
#
# The symbol should be copied as-is from the place where it was previously
# defined, but the help text should be removed or replaced with something that
# explains how to fix it.

config BR2_LEGACY
	bool
	help
	  This option is selected automatically when your old .config uses an
	  option that no longer exists in current buildroot. In that case, the
	  build will fail. Look for config options which are selected in the
	  menu below: they no longer exist and should be replaced by something
	  else.

# This comment fits exactly in a 80-column display
comment "Legacy detected: check the content of the menu below"

# This option should get a new name with every buildroot release, so it defaults
# to y again for people who upgrade.
menuconfig BR2_LEGACY_CHECK_2012_11
	bool "Check for legacy config options"
	default y
	help
	  Select this option to see the config options that are present in your
	  current .config but are no longer supported by buildroot. If any of
	  the options in this menu is selected, they should be replaced with
	  something else. As long as they stay selected, the build will fail.
	  Just de-select this option to automatically remove all the legacy
	  configuration.
