2023-01-26	habanalabs/gaudi2: find decode error root cause	Koby Elbaz	1	-0/+163
	When a decode error happens, we often don't know the exact root cause (the erroneous address that was accessed) and the exact engine that created the erroneous transaction. To find out, we need to go over all the relevant register blocks in the ASIC. Once we find the relevant engine, we print its details and the offending address. This helps tremendously when debugging an error that was created by running a user workload.
