License: embed u-boot binary in FPGA bitstream

Did you get an answer I missed ?

There’s active discussion on DTB lifecycle.

>From the Xilinx boards I am aware of, there is a Xilinx primary boot loader
that then loads u-boot SPL and then U-Boot proper.

My understanding is that you can attach the hardware description DTB with
the bitstream and pass it across to U-Boot proper.
Your build system can take a base board DTS and add the FPGA devices to it
to generate the DTB.

I’ll ask an FPGA expert to comment.
