# Kconfig package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files for packages that use kconfig for configuration files.
# It is based on the generic-package infrastructure, and inherits all of its
# features.
#
# See the Buildroot documentation for details on the usage of this
# infrastructure.

# inner-kconfig-package -- generates the make targets needed to support a
# kconfig package
#
# argument 1 is the lowercase package name
# argument 2 is the uppercase package name, including a HOST_ prefix
# for host packages
# argument 3 is the uppercase package name, without the HOST_ prefix
# for host packages
# argument 4 is the type (target or host)
