Just to check - is exposing these as environment variables really the
right long-term interface? U-Boot has been moving configuration into
the control devicetree, and both of these look like properties that
would sit naturally on the u-boot,firmware-fdt-block node, with the
env var overriding for A/B slot selection only. What do you think?
