From: Fabio Estevam <[email protected]> Enable redundant environment storage in the SPI NOR flash by enabling CONFIG_ENV_REDUNDANT and defining CONFIG_ENV_OFFSET_REDUND.
Move the primary environment to 0x3f0000 and place the redundant copy at 0x3f8000, matching the existing SPI NOR layout. Having two copies of the environment improves robustness against power loss or interrupted writes and is useful for software update frameworks such as SWUpdate that modify the U-Boot environment during system updates.
