Hi fanchang,
Thank you for bringing this to our attention. Currently the drivers for MPC57xx used in the toolbox are written manually. Our intention is to follow the same approach as we currently do with ARM based processor that rely on the existence of and SDK API from where we reuse the drivers for platform initialization.
Once such SDK will become available for MPC platforms we will consider a new release.
For the moment we will continue with the patches as a sort of quick trade off.
Best regards,
Daniel
