No, I just wanted a way for U-Boot code to store data in the environment without
interference from the user. The reason I want to use the environment is that it already
exists, and it already has a mechanism for saving itself to flash.
So, the obvious question is, "well, what kind of data?". I have an idea where the user
can tell U-Boot how the board is jumpered, so that when it boots the kernel, it can modify
the device tree on-the-fly based on the jumper settings. I don't want to use the setenv
command, however, to specify these jumper settings. I want to use a new command that does
some parameter checking and performs other operations.
