Yes, although you could set uboot_defconfig to "imx" and then it would
work(around). It became clear this wasn't the solution now that U-Boot
doesn't produce u-boot.imx for ARM64.

It was legacy, 6x_upgrade was created at the beginning of our i.MX6
journey. But since we switched to U-Boot v2017.07, we used standard
bootdistro variables and renamed the script to be more generic:
upgrade.scr.
