Thanks for digging in to this more. I suspect (and I'll try and confirm
soon) that we need to take in to account:
commit 645f75f6884a22905b0e3790ca9254fa1a13216e
Author: Tom Rini <tr...@konsulko.com>

test/py: Make the number of SPL banners seen a variable
Currently we have the option to tell the console code that we should
ignore the SPL banner. We also have an option to say that we can see it
a second time, and ignore it. However, some platforms such as TI AM64x
will have us see the SPL banner three times. Rather than add an
"spl3_skipped" option, rework the code. By default we expect to see the
banner once, but boards can specify seeing it as many times as they
expect to.
