Adds UCLASS_MDIO DM class supporting MDIO buses that are probed as
stand-alone devices. Useful in particular for systems that support
DM_ETH and have a stand-alone MDIO hardware block shared by multiple
Ethernet interfaces.

Add the standard Ethernet device tree bindings (imported from v5.0 of
the Linux kernel) and implement support for reading the MAC address for
Ethernet devices in the Ethernet uclass. If the "mac-address" property
exists, the MAC address will be parsed from that. If that property does
not exist, the "local-mac-address" property will be tried as fallback.
MAC addresses from device tree take precedence over the ones stored in
a network interface card's ROM.

In order for the device to use the proper MAC address, which can have
been configured in the environment prior to the device being registered,
ensure that the MAC address is written after the device has been probed.
For devices that are registered before the network stack is initialized,
this is already done during eth_initialize(). If the Ethernet device is
on a bus that is not initialized on early boot, such as PCI, the device
is not available at the time eth_initialize() is called, so we need the
MAC address programming to also happen after probe.

When dealing with two ethernet ports and having "netretry" set
to "once", it could occur that the connection (e.g. an ARP
request) failed, hence the status of the netloop was
"NETLOOP_FAIL". Due to the setting of "netretry", the network
logic would then switch to the other network interface,
assigning "ret" with the return value of "net_start_again()".
If this call succeeded we would return 0 (i.e. success) to
the caller when in reality the network action failed.

Peter originally sent a fix, but it breaks a number of other things.
This addresses the original reported issue in a different way.
That report was:
> U-Boot has 1 common buffer to send Ethernet frames, pointed to by
> net_tx_packet. When sending to an IP address without knowing the MAC
> address, U-Boot makes an ARP request (using the arp_tx_packet buffer)
> to find out the MAC address of the IP addressr. When a matching ARP
> reply is received, U-Boot continues sending the frame stored in the
> net_tx_packet buffer.
>
> However, in the mean time, if U-Boot needs to send out any network
> packets (e.g. replying ping packets or ARP requests for its own IP
> address etc.), it will use the net_tx_packet buffer to prepare the
> new packet. Thus this buffer is no longer the original packet meant
> to be transmitted after the ARP reply. The original packet will be
> lost.
This instead uses the ARP tx buffer to send async replies in the case
where we are actively waiting for an ARP reply.

When a USB ethernet device is halted, the device driver is removed. When
this happens the uclass private memory is freed and uclass_priv is set to
NULL. This causes a data abort when uclass_priv->state is then set to
ETH_STATE_PASSIVE.
Fix it by checking if uclass_priv is NULL before setting uclass_priv->state

Instead of depending on a env callback for bootfile, read it explicitly.
We do this because the bootfile can be specified on the command line and
if it is, we will overwrite the internal variable. If a netboot_common()

With driver model, we were not checking if the state of the device was
marked as active before calling the halt function. Check that the device
is probed and also marked as active. This avoids the case where we were
calling halt on the first device in net_init() and the driver would
operate on bogus data structures causing problems. In this case, the
priv was all 0, so halt() would close STDIN.

Currently we can choose between 2 different types of behavior for the
serverip variable:
1) Always overwrite it with the DHCP server IP address (default)
2) Ignore what the DHCP server says (CONFIG_BOOTP_SERVERIP)
This patch adds a 3rd option:
3) Use serverip from DHCP if no serverip is given
(CONFIG_BOOTP_PREFER_SERVERIP)
With this new option, we can have the default case that a boot file gets
loaded from the DHCP provided TFTP server work while allowing users to
specify their own serverip variable to explicitly use a different tftp
server.

We can call commands like dhcp and bootp without arguments or with
explicit command line arguments that really should tell the code where
to look for files instead.
Unfortunately, the current code simply overwrites command line arguments
in the dhcp case with dhcp values.
This patch allows the code to preserve the command line values if they
were set on the command line. That way the semantics are slightly more
intuitive.
The reason this patch does that by introducing a new variable is that we
can not rely on net_boot_file_name[0] being unset, as today it's
completely legal to call "dhcp" and afterwards run "tftp" and expect the
latter to repeat the same query as before. I would prefer not to break
that behavior in case anyone relies on it.

Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or
time out if no WoL packed is received.
If the WoL packet contains a password, it is saved in the environment
variable 'wolpassword' using the etherwake format (dot or colon
separated decimals).
Intended use case: a networked device should boot an alternate image.
It's attached to a network on a client site, modifying the DHCP server
configuration or setup of a tftp server is not allowed.
After power on the device waits a few seconds for a WoL packet. If a
packet is received, the device boots the alternate image. Otherwise
it boots the default image.
This method is a simple way to interact with a system via network even
if only the MAC address is known. Tools to send WoL packets are
available on all common platforms.
Some Ethernet drivers seem to pad the incoming packet. The additional
padding bytes might be recognized as Wake-on-LAN password bytes.
By default enabled in pengwyn_defconfig.

Global variable "net_state" is used in net_loop() state-machine.
But it happens that some times the net_loop() can be called
multiple times in the same call stack. For example when the
netconsole is enabled and we print the message while some other
net protocol is in action. Netconsole will overwrite the "net_state"
and that will break the logic for earlier started protocol.
To protect the state save and restore "net_state" variable each
time when we enter and exit net_loop().

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 "net_try_count" counter starts from "1".
And the "retrycnt" contains requested amount of retries.
With current logic, that means that the actual retry amount
will be one time less then what we set in "netretry" env.
For example setting "netretry" to "once" will make "retrycnt"
equal "1", so no retries will be triggered at all.
Fix the logic by changing the statement of "if" condition.
