So when I run the patches on actual DRA72x HS and DRA74x HS hardware
I'll get the device name/type output by SPL as expected so that piece
works. However this patch's commit message  implies the same should also
work on AM437x HS which it doesn't. I don't have AM437x non-secure
hardware at my desk but I looked at some boot logs from our test farms
and I also don't see the device ID output by SPL so that may be just how
it currently is implemented generally for AM437* and has nothing to do
with the patch discussed here.

Madan, please comment/chime-in as needed.
