I am aware of it - I have already pointed out that we get many patches
that have increased the default environment to something hard to
maintain. This patch makes it more obvious.

I understand the point - but is the way to hard code together with
u-boot the right way ? Do we have some other possibilities to do this ?

Maybe can be mkenvimage a solution (tools/mkenvimage) ? It creates an
environment image from a simple ASCII text. The resulting image could be
concatenated together with u-boot and in CONFIG_EXTRA_ENV_SETTINGS we
could have for all boards a way to load it. Only a first idea, but as we
recognize the issue, any idea to solve it ?

Best regards,
Stefano Babic
