Dear Simon Glass,

At present U-Boot environment variables, and thus scripts, are defined by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text to this file and dealing with quoting and newlines is harder than it should be. It would be better if we could just type the script into a text file and have it included by U-Boot.
Add a feature that brings in a .env file associated with the board config, if present. To use it, create a file in include/configs with the same name as you could board config file, except with a .env extension instead of a .h extension. The variables should be separated by \0. Comments are permitted, using # as the first character in a line.
Please do not litter the include/configs/ directory with such stuff. It's more than big enough already. Please put such files into the respective board directories.
And if you do something like this, then please go the way to the end. Forget about the \0 termination, make it a plain text file instead, something that can be used with "env import -t" as well (or created with "env export -t").
What about allowing a binary created with mkenvimage to be built-in. This would give us a standard build rule to build a separate env binary as well.
