Yes, of course - it makes sense to find a solution that will be accepted
before implementing it - this is the reason I prepared a way to enable
caches, but I have not yet done and I will not do if this solution will

Ok, understood. Let's see if we can merge soon the patchset into

TI. And then we can proceed optimizing with DMA or d-cache.

Best regards,
