Ouch, having to depend on Go for such a simple tool is indeed not very
nice :-/

I agree. Unfortunately, downloading directly
http://git.pengutronix.de/?p=barebox.git;a=blob_plain;f=scripts/socfpga_mkimage.c;h=$(MKPIMAGE_VERSION);hb=HEAD
doesn't work because this URL contains ';' which our download
infrastructure doesn't like much.

However, this program is so simple that I would advocate taking the
makedevs route: simply integrate the program source code itself inside
Buildroot, in package/mkpimage/.

Thanks,

Thomas
