In upcoming freescale board LX2160AQDS, the MDIO bus is muxed.
i.e. same MDIO bus can be routed to eight different slots depending
on mux register settings.
To support this mdio mux behavior, we add each MDIO bus mux as a
separate MDIO bus.
Now, various phy devices can be attached to each of these slots(mux).
The information about these devices is passed to OS via device tree.
To do the fdt fixups related to MDIO bus, its necessary that MDIO bus
list is accessed.Therefore, add a function to retrieve the list head.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The most of ethernet drivers are using this mdio registration sequence.
strcpy(priv->bus->name, "emac");
mdio_register(priv->bus);
Where driver can be used only with one MDIO bus because only unique
name should be used.
Other drivers are using unique device name for MDIO registration to
support multiple instances.
snprintf(priv->bus->name, sizeof(bus->name), "%s", name);
With DM dev->seq is used more even in logs
(like random MAC address generation:
printf("\nWarning: %s (eth%d) using random MAC address - %pM\n",
dev->name, dev->seq, pdata->enetaddr);
)
where eth%d prefix is used.

to simplify mdio registration and reduce code duplication across
all drivers. With DM_SEQ_ALIAS enabled dev->seq reflects alias setting.

It is confusing that mdio commands work and report phy id as
decimal value when mii is working with hex values.
For example:
ZynqMP> mdio list
gem:
21 - TI DP83867 <--> ethernet@ff0e0000
ZynqMP> mdio read ethernet@ff0e0000 0
Reading from bus gem
PHY at address 21:
0 - 0x1140
ZynqMP> mii dump 21 0
Incorrect PHY address. Range should be 0-31
...
ZynqMP> mii dump 15
0. (1140) -- PHY control register --
(8000:0000) 0.15 = 0 reset
U-Boot normally takes hex values that's why this patch is changing mdio
command to handle hex instead of changing mii command to handle decimal
values.

The following code will alloc memory for new_dev and ldev:
"

ldev = malloc(sizeof(*ldev));
"
Either new_dev or ldev is NULL, directly return, but this may leak memory.
So before return, using free(ldev) and mdio_free(new_dev) to avoid
leaking memory, also free can handle NULL pointer.

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support
The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).
The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.
We now have MDIO drivers and PHY drivers
An MDIO driver provides:
read
write
reset
A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed
The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()
Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)
We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.
We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,
we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.
