Hi,

Can someone explain me why start and end parameters are ignored in r4k_flush_cache_range_d32i32() and cache range flushing operations for other platforms?

Afair the reason was that most invokations cover a range that is larger than the entire cache anyway so our implementation in practice doesn't cause any harm.
