I was thinking something like:  [flash-sector-size] <= [U-Boot-configured-env-size]
and you must give the right number to the env image generation program.

Yes, should be possible. If you're using redundant environments, you
probably want to use the env copy that has "0x01" in the 5:th byte.
See common/env_flash.c and include/environment.h.
