What is the value of the B bit in CP15 SCR register? I wonder if RBL is
doing all the IMB operations required after copying the SPL image and
before executing it. IMB is required for consistency between data and
instruction sides.
Only if caches are used, right? Or also without caches?

Regards, Christian
Only D-cache seems to be disabled in this case. I-cache and Write
buffer are likely to be enabled. If so, all the IMB operations except
the data-cache flushing are still relevant.
