cc1ba84637 Found the ahb burst bug. 
We had instruction fetches fixed HSIZE = 2 (4 bytes) for all requests.  It should be HSIZE = 3 (8 bytes) for cache fetches and 4 for uncached reads.  The reason this worked for non burst is the DDR4 memory controller returns the full double word even for 4 byte reads.  In burst mode the second beat ending up pointing to the next 4 bytes rather than the next 8 bytes.

ddd9c507fe Trade off. Added additional state to bus fsm separating STATE_CACHE_ACCESS into STATE_CACHE_FETCH and STATE_CACHE_EVICT. This allows removing CacheRWDelay. Saves a bit of logic but fsm is more complex. Also the fsm outputs are simplier. 2022-08-31 10:36:30 -05:00
