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.

Subject: [yocto] 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.
