Hm... if the image cannot run anyway without initialized SDRAM TLB, then why do you scan for it? My understanding is that the result wouldbe the same even if you omitted this test: without initialized SDRAM TLB the system would just hang / crash without error message. So this test is dead code. Or am I missing something?
