On OpenRISC the icache does not snoop data stores. This can cause aliasing as reported by Jan. This patch fixes the issue to ensure icache is properly synchronized when code is written to memory. It supports both SMP and UP flushing. This supports dcache flush as well for architectures that do not support write-through caches; most OpenRISC implementations do implement write-through cache however. Dcache flushes are done only on a single core as OpenRISC dcaches all support snooping of bus stores.
