  17 # Adds a target for creating a package containing
  18 # the specified (kernel-provided) modules.
  19 # Parameters:
  20 # 1: the config symbol name (without leading 'ADK_[K,]PACKAGE_KMOD_')
  21 #    this _must_ be equal to the kernel config symbol name
  22 # 2: the name for the package, should be unique
  23 # 3: actual modules to add; absolute path inside $(MODULES_DIR)
  24 #    OMIT THE KERNEL-SPECIFIC EXTENSION!
  25 # 4: order of module loading at system startup; the modules in $(3) are (in their order)
  26 #    added to this file, if $(6) is non-empty
  27 # 5: the kmod packages this package depends on
