U-Boot binary has grown in such a way that it goes beyond the reserved area for the environment variables.
Running "saveenv" and rebooting the board causes U-Boot to hang because of this overlap.
Fix this problem by selecting CONFIG_LTO so that the U-Boot proper size can be reduced.
Also, to prevent this same problem to happen in the future, use CONFIG_BOARD_SIZE_LIMIT, which can detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT is calculated as follows:
CONFIG_BOARD_SIZE_LIMIT = CONFIG_ENV_OFFSET - u-boot-img.dtb offset CONFIG_BOARD_SIZE_LIMIT = 0xc000 - 69 * 1024 CONFIG_BOARD_SIZE_LIMIT = 715766

Applied all, thanks.
