* Added Marvell Phy Gigabit support in U-Boot ver 2.0.0
* New env variables select the primary phy and link speed negotiation:
'''cpsw [0|1]''' : if present, select primary phy for networking operations in uboot
0 = phy 6 -> 100Mbit Naon module
1 = phy 1 -> 1Gbit external, EVB-Lite and EVB-Mid
'''giga [on]''' : if present, select gigabit speed on gigabit link, if not present speed link is '''default 100Mbit'''
===Notes on root file system===
NELK root file system derives directly from the one delivered along with TI EZSDK. In order to enrich it by installing new pre-built packages, well-known opkg tool comes to help.
