As far I can remember you can't boot the SoCFPGA without the SPL being
"signed" (which is really a simple header with a CRC and some padding so it
fits a precise size).
I'm curious how you made one boot without this as per Altera's
documentation the Boot ROM needs it. Note that in Qsys, it's already done
in their various scripts, so if you build U-Boot that way, it's done for
you.
There's no real added value as far as I could tell, the SoC needs it,
that's all. And there's no DIP switch which helps you configure that on the
dev kit. I don't think you can configure it. You have to do it and that's
pretty much it.
