The following set of patches modifies kernel RapidIO subsystem to enable build and use of its components as loadable kernel modules. Combinations of statically linked and modular components are also supported.
For this release full RapidIO subsystem modularization is implemented for x86-based platforms. For PowerPC platforms (mostly MPC85xx) RapidIO core and the mport driver (fsl_rio.c) still have only statically linked build option while other components (enumerator and switch drivers) can be built as kernel modules. This is not a significant limitation for embedded PowerPC platforms because they use on-chip RapidIO controllers. For PowerPC platforms that may use an external PCIe RapidIO controller (e.g. Tsi721) an additional patch will be provided later. This set of patches is based on the current linux-next code tree that contains previously submitted patches for modularized enumeration/discovery method.
