Ross Thompson	cb34b7c98f	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.	2022-09-17 20:30:01 -05:00
