/*
 * \brief  Linux-specific core implementation of the ROM session interface
 * \author Norman Feske
 * \date   2006-07-06
 *
 * The Linux version of ROM session component does not use the
 * Rom_fs as provided as constructor argument. Instead, we map
 * rom modules directly to files of the host file system.
