Without this patch, when the currently chosen environment to be written has bad blocks, saveenv fails completely. Instead, when there is redundant environment fall back to the other copy.

Isn't this what CONFIG_ENV_RANGE is supposed to deal with?
Redundant environment is to deal with other problems such as a power failure during saveenv. If you just fall back to the other copy, you're silently losing the redundancy.
