Would you prefer this to go through u-boot/net or would you prefer to
pull it in directly? It has a fair amount of env and test changes.

Speaking of, are you the maintainer of the "env" area of the code?
Wolfgang used to comment on it primarily, so I don't know if that role
went to you along with mainline.

Please let me know... Thanks,
