This commit provides the ability to generate u-boot environment(s) as images, which afterwards can be used to produce image (with wic) for flashing (eMMC or SPI-NOR).
This change removes the need to run "env default" during production phase, as proper environment (including redundant one) is already stored on persistent memory (the CRC is also correct).
