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 increasing the CONFIG_ENV_OFFSET.
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 = 0xd000 - 69 * 1024 CONFIG_BOARD_SIZE_LIMIT = 781312

I don't like when we have to move the environment like this, can we trim things down instead? Perhaps LTO?
