Use a script to auto-install your board. Expect is a great tool.

No. Expect is based on tcl, and tcl is available for other host environments, too, including Solaris, HP-UX and Windows.
tools as simple as Hyperterminal, or even without serial line at all.
AFAIK even HT understands some form of "scripting".
Since U-Boot does have a enviroment area. the natural place to put compile time initialization is in the environment area and compile the environment as a separate entity which is linked to the environment. You can define a sector in the <board>.lds. It will not handle "reset to factory defaults" though.
Then you can have compile time initialization AND if you so choose, you could during production decide to first program u-boot into the flash, and then afterwards modify the environment. On a dataflash that is easy, since the minimium erase block is 1056 bytes and you have several blocks in the environment area.
Doing it this way, still require you to *create* the environment data Until there is a configuration method which allows your grandmother to get networking running my proposed patch is still useful.
Without serial line, you can use one of the other approaches I explained several times during the last two days. They work for others, and theycould work for you, too, it you tried. Without chnages to the code, mind you.
If you, like me, dont deliver any boards, then you do not have this problem.
Indeed, it's a SEP instead - Somebody Else's Problem.
It is the reponsibility of the user of the S/W to ensure that it is used in a restricted environment like production or development where the MAC address can be selected at random.
Making life easy for you and difficult for the user is only one of the many possible ways of working. It's not my preferred way.
My goal is to make it easier for the user, and I hopefully will at a later stage will have a small application which will generate a board specific script which can be installed on the production PC and run once per board.
Currently the ethernet address is already set by u-boot. It is set to 00:00:00:00:00:00, making it impossible to communicate over ethernet.
