U-Boot binary has grown in such a way that it goes beyond the reserved area for the environment variables.
Running "saveenv" followed by a "reset" causes U-Boot to hang because of this overlap.
Fix this problem by selecting CONFIG_SYS_THUMB_BUILD=y, which generates a smaller u-boot-dtb.imx binary.
Also, in order to prevent this same problem in the future, use CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare CONFIG_ENV_OFFSET with its direct value instead.

Thanks for the rework. Can you please look at what other i.MX boards are likely fine, or perhaps more clearly if any i.MX5/6 SoCs do have thumb2 related errata that might make it a bad idea to use thumb by default ?
