Not sure I'm getting this, so for my own education: what prevents from invalidating the cache, or IOW, what would happen if it was invalidated at this point rather than flushed?
This is a hardware limitation. The nios2 cpu with 4 bytes dcache line size does not support the initda instruction, which is needed to invalidate dcache.
Recently we added a check, if the nios2 cpu support initda instruction, then we use invalidate_dcache, otherwise we use flush_dcache.
