This thread is a continuation of "GSoC 2020: Implementation of OFW functions".
A summary of points discussed in that thread is given below. Below is a short description of my GSoC project. For more information please refer to the wiki. https://devel.rtems.org/wiki/GSoC/2020/Beagle_FDT_initialization My GSoC project deals with refactoring the Beagle BSP to add support for FDT based initialization. As part of this process, I will have to import the pin mux driver into RTEMS which currently is present in libBSD. This would require having support for OFW functions which are currently not implemented in RTEMS. Some drivers(eg: imx_iomux.c) which require these functions provide a local implementation using libFDT. In the previous thread, it has been decided to import the OFW functions from FreeBSD but the directory where it has to be imported into RTEMS is not yet decided. This thread has been created to discuss it. It should also be noted that some drivers for example I2C, SPI are being imported into RTEMS from FreeBSD for some BSPs. Now, since a large amount of code being imported from FreeBSD it is planned to add to a synchronization script(Yet to discussed in detail) to stay in sync with FreeBSD. So now is it necessary to choose a directory that is future compatible with the synchronization script. We should also discuss if we want to have all imports under a single directory or have the imports in their respective directories for eg a device driver could be placed in its BSP directories than in a common folder along with other imports. But it should also be noted that the latter makes it difficult to sync and the former. Thanks, Niteesh.
