#
# Adds a target for creating a package containing
# the specified (kernel-provided) modules.
# Parameters:
# 1: the config symbol name (without leading 'ADK_[K,]PACKAGE_KMOD_')
# this _must_ be equal to the kernel config symbol name
# 2: the name for the package, should be unique
# 3: actual modules to add; absolute path inside $(MODULES_DIR)
# OMIT THE KERNEL-SPECIFIC EXTENSION!
# 4: order of module loading at system startup; the modules in $(3) are (in their order)
# added to this file, if $(6) is non-empty
# 5: the kmod packages this package depends on
#
