I don't use Stratix10 but Cyclone5, but as I need a .hex to boot from 
FPGA, I want to know how to solve this best.

So to understand this, again a question: is this the only way to boot 
Stratix10? Or one of the possible boot methods?
Because reading "Intel® Stratix® 10 SoC FPGA Boot User Guide", it seems 
like you would need the hex for "FPGA Configuration First Mode", but not 
for "HPS Boot First Mode"?

If so, it would make Stratix10 and Cyclone5 more alike and a 
configuration option (like "Boot from FPGA") could be used to control 
CONFIG_OF_EMBED and enable creating the hex file for SPL.

I *am* working on fixing the "boot from FPGA" case for Cyclone5, so I'd 
appreaciate it if we could share as much as possible between those 
sub-architectures.
