Please try the latest patches on top of phy -next (with PHY interface mode), available there [1]. You can pick only the COMPHY patches, but keep them over the phy -next branch.
Please note that for the SMC calls to succeed you must use a recent ATF. Personally I used to work with the 'atf-v1.5-devel' branch of Marvell's misl-atf repository but it is not available anymore. If you already have a clone, then you are good to go, otherwise it might be great if someone from Marvell could share a public Github link?

In theory yes, unfortunately I am working on an EspressoBin which uses the SATA, PCIe and SATA configurations of the COMPHY, but not the Ethernet ones (SGMII/1000BASE-X and HS_SGMII/2500BASE-X). So the support is ready to be tested!
