We have also merged everything back into one Variant MPC5xxx. However we do require some changes to the PowerPC main architecture. Those are mandatory for our contribution. In detail the following things: - cache Macro: The current arch uses a Macro HAL_UCACHE_ENABLE to differentiate between CPUs with unified cache versus Harvard. In all other Architectures thise is actually a macro for a function call. Since many of our devices use the e200z6 core, which does actually have a unified cache, I have renamed that original Macro to HAL_CACHE_IS_UCACHE and use the other Macro as in the other architectures - default setting for PowerPC Book E - since all devices of the MPC5xxx variant are Book E I would like to set this for all devices of that variant - Exception tables: Several of our supported devices use the e200z1, which has a reduced set of exception registors (IVOR Registers are missing). I build that into the arch. Please integrate those patches, so that we can contribute the rest of the files.
