It depends. I can put around #ifdef resume. But I dont think its a 
proper fix. I dont know much about ECC so I dont know what is the 
correct way to fix that.
If all ECC tags must be cleared by memory write, the code is also wrong 
because it zero out memory only to TOPK and not to MEMTOP or MEMTOP2
