As the icache and dcache of nios2 are always enabled, the cmd_cache is no of use and the cache status, enable and disable functions can be removed.
This is no good, I want to be able to enable/disable caches to look for DMA-related issues. That is, if I disable cache, the suspicious driver works and if I enable cache, the driver does not work, I can conclude that it's a DMA/cache-related issue.
