This [the maintainers] list is not really for technical questions. That said, the proper HAL variant would be the PPC60x. Your platform would be a target that uses this variant. Since the 750 has no builtin I/O (as most of the other PPC platforms do), you'll have some work to port various I/O drivers (serial, interrupts, ethernet, ...) We don't really have a similar PPC platform to give as an example. This may be a non-trivial task (I don't know much about your board), but you may want to consider [professional] help. The online documentation can guide you, but it's still going to be an effort.
