This is a perfectly valid requirement. It pops up with  many  vendors
who  use U-Boot on their boards. Many actually use this in production

Some read data from a special flash area, others run a script  stored
in  flash.  Some  leave this script in the flash after production and
eventually use it for example to implement reset to factory defaults,
others  erase  or  overwrite  it  or  use  self-deleting  environment
variables for a run-once setup.

I agree with you that  the  way  how  U-Boot  gets  configured  needs
improvement,  but  instead  of implementing some "backdoor" to inject
configuration information from a tool that lives outside  the  U-Boot
tree we should try and improve the U-Boot code.

You are welcome to contribute  to  this,  but  please  let's  discuss
design  and implementations first, before submitting patches that may
lead to discussions that are frustrating for both sides.

Best regards,

I used to be indecisive, now I'm not sure.
