PS2, Line 12: Platforms with SMM_TSEG=y always need to implement
            : stage_cache_external_region(). It is allowed to return with a
            : region of size 0 to effectively disable the cache.
It just happens to be that all platforms with SMM_TSEG also implement stage_cache_external_region() but afaict there is no hard requirement to do so.
