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?
Tom

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.
