Building Yocto for FPGA boot first config on Agilex 7

Hello Jeetesh

Thank you for the link you've sent. But the problem is that I need to disable booting FPGA on SSBL stage and I couldn't find where is it can be disabled in U-Boot while compiling sd card image with Yocto.

I could only find something that controls booting process in file:

gsrd_socfpga/meta-intel-fpga-refdes/recipes-kernel/linux/linux-socfpga-lts/fit_kernel_agilex_fm87.its

		fpga-4 {
			description = "FPGA bitstream for GHRD";
			data = /incbin/("./ghrd.core.rbf");
			type = "fpga";
			arch = "arm64";
			compression = "none";
			load = <0xA000000>;
			hash {
				algo = "crc32";
			};

And during booting it can bee seen in a log

## Loading fpga from FIT Image at 02000000 ...

Hello!

Yes this is exactly what i'm looking for as at the moment of booting from SD card I already have the FPGA configured.

Hello Tiwari

Thank you for this link. I'm going to try it and see if it works for me.

Yeap I managed to build Yocto with FPGA boot first config.

Thank you.
