[U-Boot] [PATCH 0/3] add support for VSC8584 and VSC8574 Microsemi PHYs

[Quentin Schulz]

The VSC8584 and VSC8574 PHYs are 4-port PHYs that are 10/100/1000BASE-T,
100BASE-FX, 1000BASE-X and triple-speed copper SFP capable, can communicate
with the MAC via SGMII, QSGMII or 1000BASE-X, supports WOL, downshifting
and can set the blinking pattern of each of its 4 LEDs, supports SyncE as
well as HP Auto-MDIX detection.

This adds support for 10/100/1000BASE-T and SGMII/QSGMII link with the
MAC.

They have also an internal Intel 8051 microcontroller whose firmware needs
to be patched when the PHY is reset. If the 8051's firmware has the
expected CRC, its patching can be skipped. The microcontroller can be
accessed from any port of the PHY, though the CRC function can only be done
through the PHY that is the base PHY of the package (internal address 0)
due to a limitation of the firmware.

The GPIO register bank is a set of registers that are common to all PHYs
in the package. So any modification in any register of this bank affects
all PHYs of the package.

Thanks,
Quentin
