I had thought about that, but there is an issue. main_loop() sets this env var,
so if ver is made read-only and the env is stored somewhere (NVRAM, etc.), then
after an update of U-Boot with a newer version (stored env untouched), ver will
still indicate the older version. See commit 155cb01, which forgot to update the
README file, which my patch does.

Best regards,
Benoît
