I understand although as it is said in the commit log, the previous
scripts will be removed in a future release.

As for where those scripts are located, we actually have them in our
U-Boot repo now:
https://github.com/boundarydevices/u-boot-imx6/tree/boundary-v2017.07/board/boundary/bootscripts

That is how it is used in Yocto. I don't mind using it from U-Boot
directly, but what's the best way to do so? Is there a bootloader
equivalent to LINUX_DIR so I can easily point to the bootloader
source?

Also, would you guys be ok with a
BR2_TARGET_UBOOT_BOOT_SCRIPT_INSTALL_TARGET option? That would reduce
the post-build script for several configs which copies it manually to
TARGET_DIR/boot/ right now.

Regards,
Gary
