Altera Cyclone V u-boot-spl with meta-altera

Hi, I am using meta-altera layer (https://github.com/kraj/meta-altera) 
to build u-boot for Altera Cyclone V socfpga board. Building the 
u-boot-socfpga_2013.01.01 recipe does generate the u-boot-spl binary, 
but it cannot be directly used on the board as it has to be signed using 
Altera's tool "mkpimage" that comes with Altera's toolset (SoC EDS 
<http://rocketboards.org/foswiki/view/Documentation/AlteraSoCDevelopmentBoardYoctoGettingStarted#SoC_EDS>). 


Is there a way to produce a signed u-boot-spl image during the build, 
that can be used directly on the target without using the EDS?

Thanks,
Fahad.

I’m not aware of a tool outside of Altera’s EDS mkpimage. What I ended up doing was installing a subset of the EDS tools (mkpimage and the jre directory), then tweaked the u-boot spl/Makefile to automatically invoke mkpimage to create the preloader. I also tweaked the meta-altera u-boot-socfpga.inc do_deploy() rules to copy the newly built preloader-mkpimage-* files to the deploy directory.

I’d be happy to send those to you, if you’re interested. Likewise, if you find a third party tool to add the preloader image header, let me know.

If you upgrade to the U-Boot 2016.01 (or maybe even earlier?), mkimage
actually supports adding the Bootrom signature to the SPL for you.  The
current makefile is kind enough to concatenate the U-Boot SPL and its DTS
for you, and then run mkpimage to create an 'spl/u-boot-spl-dts.sfp' file
[1].

If that doesn't work for you, you might find [2] to be useful.  The bootrom
"signature" is simple enough to implement in a do_compile_append() or
custom task.

Thanks Jon Szymaniak,
I was not aware that the bootrom signature support has been added to the 
current version of u-boot. I was able to built the 
u-boot-with-spl-dtb.sfp target and the single concatenated u-boot file 
worked on Cyclone 5 board right away.

Fahad.
