Several in the imx family, all of which appear to be building
reproducibly:

$ zgrep CONFIG_OF_CONTROL=y usr/share/doc/u-boot-imx/configs/config.*
usr/share/doc/u-boot-imx/configs/config.dh_imx6.gz:CONFIG_OF_CONTROL=y
usr/share/doc/u-boot-imx/configs/config.mx6cuboxi.gz:CONFIG_OF_CONTROL=y
usr/share/doc/u-boot-imx/configs/config.mx6qsabrelite.gz:CONFIG_OF_CONTROL=y
usr/share/doc/u-boot-imx/configs/config.nitrogen6q.gz:CONFIG_OF_CONTROL=y
usr/share/doc/u-boot-imx/configs/config.novena-rawsd.gz:CONFIG_OF_CONTROL=y
usr/share/doc/u-boot-imx/configs/config.novena.gz:CONFIG_OF_CONTROL=y
usr/share/doc/u-boot-imx/configs/config.wandboard.gz:CONFIG_OF_CONTROL=y

dh_imx6 did have reproducibility issues around u-boot 2020.04, but
haven't seen them in 2020.07-rc1 or newer, so I haven't bothered to
bisect or look into it further.

CONFIG_OF_CONTROL is enabled in many other boards in the Debian packages
without issue.

The dra7xx_evm platform has reproducibility issues introduced
approximately the same time, but I haven't been able to trigger the
issue in my local test environment (which is a little less comprehensive
than what tests.reproducible-builds.org does). I'll try to do some more
testing of that one soon, but that should probably be it's own thread as
it seems unrelated.

live well,
