As we've integrated the mkpimage, we just leave some notes
about other available tools and give an advice how to enable
this feature in Buildroot.

Signing the Preloader
---------------------
-*** BEWARE ****
-The u-boot-spl.bin must be signed using the Altera's tool "mkpimage".
-This tool comes as a part of the Altera development environnment (SoC EDS).
-A fork of this tool have been done by Maxime Hadjinlian and can be found here :
-https://github.com/maximeh/mkpimage
+The u-boot-spl.bin needs a checksum computed by the Altera's tool "mkpimage".
+This tool comes as a part of the Altera development environnment (SoC EDS),
+as a standalone tool https://github.com/maximeh/mkpimage and as a part of the
+Barebox project. The boards do not boot without the checksum.
-Remember that without signing the u-boot-spl.bin, the board will not boot !!!
+The Buildroot integrates the mkpimage and you can find it in the configuration.
+If you check: "Bootloaders/U-Boot/CRC SPL image for SoC FPGA" the build system
+calls mkpimage on the SPL for you automatically.
- $ mkpimage u-boot-spl.bin -o u-boot-spl-signed.bin
+ $ mkpimage u-boot-spl.bin -o u-boot-spl.bin.crc
