/*

|
* \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.
