Why only 10 Mb/s ? I think the Micrel 9031 allows 1Gb/s.
I will check again, I remember this solves an issue present also in sabrelite board; but not sure. Maybe we can remove.
Ok - I know the Nitrogen (aka sabrelite) is working fine with 100Mb, I am worrying that you will constrain the udoo to 10Mb/s

- ksz9021_phy_extended_write(phydev,
MII_KSZ9021_EXT_RGMII_RX_DATA_SKEW, 0x0);Is is 9021 or 9031 ?
uDoo adopt a Micrel KSZ9031 phy. Most of the register address are common to ksz9021 and ksz9031, and have the same value. Maybe we should rename some variable to MII_KSZ90XX_...

SABRE as comment is maybe wrong
+#define CONFIG_PHY_MICREL_KSZ9021
Ok, it is 9021 - please be consistent with the comments avoiding mixing 9031 and 9021.
No, it is 9031. I will create a new define.
Mmmhh... I remember I did some work with KSZ9031 some times ago, let me see:

Joe, what is the current status of that patchset ?
