[U-Boot] call env print from uboot environment

[John Stile]

I am finally on uboot-2013.01.
I having issue using: env import

I have at91bootstrap reading an uboot environment from an address
location in NAND to RAM address 0x20000000.

The environment uboot is compiled to load by default has one set of
variables, but the environment loaded into ram by  at91bootstrap is
different.

I hope to see the change by using: env print.
