After the discussion here:

which resulted in this patch:
https://patchwork.kernel.org/project/netdevbpf/patch/20210704134325.24842-1-pali@kernel.org/
and many other discussions before it, notably:
https://patchwork.kernel.org/project/linux-arm-kernel/patch/1512016235-15909-1-git-send-email-Bhaskar.Upadhaya@nxp.com/
it became apparent that nobody really knows what "SGMII 2500" is.
Certainly, Freescale/NXP hardware engineers name this protocol
"SGMII 2500" in the reference manuals, but the PCS devices do not
support any "SGMII" specific features when operating at the speed of
2500 Mbps, no in-band autoneg and no speed change via symbol replication
. So that leaves a fixed speed of 2500 Mbps using a coding of 8b/10b
with a SERDES lane frequency of 3.125 GHz. In fact, "SGMII 2500 without
in-band autoneg and at a fixed speed" is indistinguishable from
"2500base-x without in-band autoneg", which is precisely what these NXP
devices support.
So it just appears that "SGMII 2500" is an unclear name with no clear
definition that stuck.
As such, in the Linux kernel, the drivers which use this SERDES protocol
use the 2500base-x phy-mode.
This patch converts U-Boot to use 2500base-x too, or at least, as much
as it can.
Note that I would have really liked to delete PHY_INTERFACE_MODE_SGMII_2500
completely, but the mvpp2 driver seems to even distinguish between SGMII
2500 and 2500base-X. Namely, it enables in-band autoneg for one but not
the other, and forces flow control for one but not the other. This goes
back to the idea that maybe 2500base-X is a fiber protocol and SGMII-2500
is an MII protocol (connects a MAC to a PHY such as Aquantia), but the
two are practically indistinguishable through everything except use case.
NXP devices can support both use cases through an identical configuration,
for example RX flow control can be unconditionally enabled in order to
support rate adaptation performed by an Aquantia PHY. At least I can
find no indication in online documents published by Cisco which would
point towards "SGMII-2500" being an actual standard with an actual
definition, so I cannot say "yes, NXP devices support it".

It is an unfortunate reality that some PHY settings done by U-Boot
persist even after the PHY is reset and taken over by Linux, and even
more unfortunate that Linux has come to depend on things being set in a
certain way.
For example, on the NXP LS1028A-RDB, the felix switch ports are
connected to a VSC8514 QSGMII PHY. Between the switch port PCS and the
PHY, the U-Boot drivers enable in-band auto-negotiation which makes the
copper-side negotiated speed and duplex be transmitted from the PHY to
the MAC automatically.
The PHY driver portion that does this is in vsc8514_config():
/* Enable Serdes Auto-negotiation */
phy_write(phydev, MDIO_DEVAD_NONE, PHY_EXT_PAGE_ACCESS,
PHY_EXT_PAGE_ACCESS_EXTENDED3);
val = phy_read(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON);
val = val | MIIM_VSC8574_MAC_SERDES_ANEG;
phy_write(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON, val);
The point is that in-band autoneg should be turned on in both the PHY
and the MAC, or off in both the PHY and the MAC, otherwise the QSGMII
link will be broken.
And because phy_config() is currently called at .port_enable() time, the
result is that ports on which traffic has been sent in U-Boot will have
in-band autoneg enabled, and the rest won't.
It can be argued that the Linux kernel should not assume one way or
another and just reinitialize everything according to what it expects,
and that is completely fair. In fact, I've already started an attempt to
remove this dependency, although admittedly I am making slow progress at
it:
https://patchwork.kernel.org/project/netdevbpf/cover/20210212172341.3489046-1-olteanv@gmail.com/
Nonetheless, the sad reality is that NXP also has, apart from kernel
drivers, some user space networking (DPDK), and for some reason, the
expectation there is that somebody else initializes the PHYs. The kernel
can't do it because the device ownership doesn't belong to the kernel,
so what remains is for the bootloader to do it (especially since other
drivers generally call phy_config() at probe time). This is a really
weak guarantee that might break at any time, but apparently that is
enough for some.
Since initializing the ports and PHYs at probe time does not break
anything, we can just do that.

When using uclass_get_device* to get the FEC device we need to use
device sequence instead of index into UCLASS_ETH. In systems where for
example a I2C based DSA switch exists it will probe before the FEC
master and its ports will be registered first and have the first
indexes yet the FEC's sequence comes from the device-tree alias.
Take for example the imx8mm-venice-gw7901 board which has an i2c based
DSA switch:
u-boot=> net list
eth1 : lan1 00:0d:8d:aa:00:2f
eth2 : lan2 00:0d:8d:aa:00:30
eth3 : lan3 00:0d:8d:aa:00:31
eth4 : lan4 00:0d:8d:aa:00:32
eth0 : ethernet@30be0000 00:0d:8d:aa:00:2e active
Thus in this case uclass_get_device(UCLASS_ETH, 0, &dev) returns lan1
which is wrong but uclass_get_device_seq(UCLASS_ETH, 0, &dev) returns
ethernet@30be000 which is correct.

The RGMII spec supports optional in-band status reporting for the speed
and duplex negotiated on the copper side, and the ENETC driver enables
this feature by default.
However, this does not work when the PHY does not implement the in-band
reporting, or when there is a MAC-to-MAC connection described using a
fixed-link. In that case, it would be better to disable the feature in
the ENETC MAC and always force the speed and duplex to the values that
were negotiated and retrieved over MDIO once the autoneg is finished.
Since this works always, we just do it unconditionally and drop the
in-band code.
Note that because we need to wait for the autoneg to complete, we need
to move enetc_setup_mac_iface() after phy_startup() returns, and then
pass the phydev pointer all the way to enetc_init_rgmii().
The same considerations have led to a similar Linux driver patch as well:
