it is binary only and was part of the TI GFX-SDK for the omap3

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html

I have repacked the files into so that our OS can easily install the correct ones

http://download.goldelico.com/letux-debian-rootfs/debian/dists/jessie/main/binary-armhf/omap-sgx530-125_0.20180825175646_armhf.deb

There is also an sgx530-121 for omap3430. But usually the libs are tied closely to the release version number of the firmware so that they
probably don't work with other DDK versions.

In the meantime I have tested my kernel versions a little and v4.15 strace works as expected.
v4.16 ends in an EFAULT within some ioctl() and v4.19 and up to v5.0-rc in some ENOMEM.
Looks as if I have lost/missed some fixes because i did only focus on compile conflicts...

BR,
Nikolaus
