Previously we had stored the environment right after the u-boot.img on the disk. I never liked this because with dtbs being included and such the image could grow in size. Instead we move the environment to be negatively offset from the 1MB mark. Almost all our images start at 4MB's, and most standard images start at 1MB, and all our storage devices are a minimum 1MB. Therefore we can store env there for all classes of devices and have plenty of space in case u-boot.img needs to grow.
