Ok, it turns out I don't need to do that update, because the
only thing that's actually used from the extra patch are the
tse850_defconfig file and the environment. But since the
tse850_defconfig file fails to set CONFIG_MACH_TSE850, the
actual code in the extra patch is not used (not even compiled).
Instead, the board code for sama5d3x is what I have been using
all along. Big blush about that, and sorry for the confusion!

However, the above also means that the quotes around the
"regressions" word in the subject can be removed. The problems
are squarely in the upstream code base, and I do need fixes
for region overlap, eXecute Never and RO_DATA_SECTION.

I have this hunch that the region overlap is what triggers
the other problems, but that's a pretty wild guess...
