[U-Boot] U-boot environment redundancy

Hello, I have some query regarding how the u-boot environment redundancy works. As per my understanding, we need to set the CONFIG_ENV_ADDR_REDUND and CONFIG_ENV_SIZE_REDUND macros in the board config file. The boot loader is supposed to read the both the environments and based on the obsolete
