Great!

I would like to add this tiny patch on top though:

Subject: [PATCH] Remove annoying debug printout for PHY less boards.

PHY less board prints out lots of "read wrong ...":
read wrong value : mii_id 3,mii_reg 2, base e0102320
read wrong value : mii_id 3,mii_reg 3, base e0102320
UEC: PHY is Generic MII (ffffffff)
read wrong value : mii_id 3,mii_reg 4, base e0102320
read wrong value : mii_id 3,mii_reg 0, base e0102320
read wrong value : mii_id 3,mii_reg 1, base e0102320
read wrong value : mii_id 3,mii_reg 1, base e0102320
read wrong value : mii_id 3,mii_reg 5, base e0102320
read wrong value : mii_id 3,mii_reg 1, base e0102320
read wrong value : mii_id 3,mii_reg 1, base e0102320
read wrong value : mii_id 3,mii_reg 5, base e0102320
FSL UEC0: Full Duplex
FSL UEC0: Speed 100BT
FSL UEC0: Link is up
Using FSL UEC0 device

Make this printout depend on UEC_VERBOSE_DEBUG and
remove its definition in uec_phy.c
