      https://source.denx.de/u-boot/custodians/u-boot-amlogic/-/commit/1f505e80e20918bcd388ccff6b33d749fbf31945

This triggered the following build https://gitlab.com/superna9999/amlogic-u-boot-autotest/-/pipelines/1019397571
which will produce ready-to-boot binaries on most of the supported platforms
