A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset from the end of the eMMC device/partition, rather than a forwards offset from the start.
This is useful when a single board may be stuffed with different eMMC devices, each of which has a different capacity, and you always want the environment to be stored at the very end of the device (or eMMC boot partition for example).
One example of this case is NVIDIA's Ventana reference board.

NAK because you aren't also covering CONFIG_ENV_OFFSET_REDUND and you need to update the README as it says ENV_OFFFSET is from the beginning not end.
