HOWTO

apply HACK-export-dma-access-functions-needed-by-PVR-drive.patch to kernel tree
Download http://software-dl.ti.com/dsps/dsps_public_sw/gfxsdk/4_10_00_01/exports/Graphics_SDK_setuplinux_4_10_00_01.bin?tracked=1 and make it executable
install it with ./Graphics_SDK_setuplinux_4_10_00_01_hardfp_minimal_demos.bin --es5.x --sdk
adjust Rules.make to your enviroment
apply Fix-compile-with-mainline-kernel-v4.15.patch
clean it before building
  make BUILD=release ARHC=arm OMAPES=5.x TI_PLATFORM=omap3630 clean
  make BUILD=release ARHC=arm OMAPES=5.x TI_PLATFORM=omap3630 clean_km
and build it with
  make BUILD=release ARHC=arm OMAPES=5.x TI_PLATFORM=omap3630 all
