beagleplay u-boot tftp and nfs

Can saveenv be used for beagleplay u-boot?

SAVEENV is disabled by default and for the new flow uses Uenv.txt as the default way for saving the environments. This has been done as Uenv.txt is more granular then the saveenv command and can be used across various bootmodes too.
