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).

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.
