82a3c9ef20 net: use the same alias stem for ethernet as linux
Linux uses the prefix "ethernet" whereas u-boot uses "eth". This is from
the linux tree:

$ grep "eth[0-9].*=.*&" arch/**/*dts{,i}|wc -l
0
$ grep "ethernet[0-9].*=.*&" arch/**/*dts{,i}|wc -l
633

In u-boot device trees both prefixes are used. Until recently the only
user of the ethernet alias was the sandbox test device tree. This
changed with commit fc054d563b ("net: Introduce DSA class for Ethernet
switches"). There, the MAC addresses are inherited based on the devices
sequence IDs which is in turn given by the device tree.

Before there are more users in u-boot and both worlds will differ even
more, rename the alias prefix to "ethernet" to match the linux ones.
Also adapt the test cases and rename any old aliases in the u-boot
device trees.

uclass is returned. This depends on the probing order of the ethernet
devices. Moreover it is not not configurable at all.

Try to return the ethernet device with sequence id 0 first which then
can be configured by the aliases in a device tree. Fall back to the old
mechanism in case of an error.

f27bc8afd5 net: phy: fixed: Be compatible with live OF tree
On systems that use CONFIG_OF_LIVE, the "ofnode" type is defined
as const struct device_node *np, while on the flat DT systems it
is defined as a long of_offset into gd->fdt_blob.

It is desirable that the fixed PHY driver uses the higher-level
ofnode abstraction instead of parsing gd->fdt_blob directly,
because that enables it to work on live OF systems.

The fixed PHY driver has used a nasty hack since its introduction in
commit db40c1aa1c ("drivers/net/phy: add fixed-phy /
fixed-link support"),
which is to pass the long gd->fdt_blob offset inside int phydev->addr
(a value that normally holds the MDIO bus address at which the PHY
responds). Even ignoring the fact that the types were already
mismatched leading to a potential truncation (flat OF offset was
supposed to be a long and not an int), we really cannot extend this
hack any longer, because there's no way an int will hold the other
representation of ofnode, the struct device_node *np.

So we unfortunately need to do the right thing, which is to use the
framework introduced by Grygorii Strashko in
commit eef0b8a930 ("net: phy: add ofnode node to struct phy_device").
This will populate phydev->node for the fixed PHY.

Note that phydev->node will not be valid in the probe function, since
that is called synchronously from phy_device_create and we really have
no way of passing the ofnode directly through the phy_device_create API.
So we do what other drivers do too: we move the OF parsing logic from
the .probe to the .config method of the PHY driver. The new function
will be called at phy_config() time.

I do believe I've converted all the possible call paths for creating
a PHY with PHY_FIXED_ID, so there is really no reason to maintain
compatibility with the old logic of retrieving a flat OF tree offset
from phydev->addr. We just pass 0 to phydev->addr now.

714555374f net: dsa: remove master santiy check
Because we probe the master ourselves (and fail if there is no master),
it is not possible that we don't have a master device.

There is one catch though: device removal. We don't support that. It
wasn't supported neither before this patch. Because the master device
was only set in .pre_probe(), if a device was removed master_dev was a
dangling pointer and transmitting a frame cause a panic. I don't see a
good solution without having some sort of notify machanism when a
udevice is removed.

e5d7d11928 net: dsa: probe master device
DSA needs to have the master device probed first for MAC inheritance.
Until now, it only works by chance because the only user (LS1028A SoC)
will probe the master device first. The probe order is given by the PCI
device ordering, thus it works because the master device has a "smaller"
BDF then the switch device.

Explicitly probe the master device in dsa_port_probe().

bdf319273b mdio-uclass.c: support fixed-link subnodes
When trying to port our mpc8309-based board to DM_ETH, on top of
Heiko's patches, I found that nothing in mdio-uclass.c seems to
support the use of a fixed-link subnode of the ethernet DT node. That
is, the ethernet node looks like

		enet0: ethernet@2000 {
			device_type = "network";
			compatible = "ucc_geth";
			...
			fixed-link {
				reg = <0xffffffff>;
				speed = <100>;
				full-duplex;
			};

but the current code expects there to be phy-handle property. Adding
that, i.e.

			phy-handle = <&enet0phy>;
			enet0phy: fixed-link {

just makes the code break a few lines later since a fixed-link node
doesn't have a reg property. Ignoring the dtc complaint and adding a
dummy reg property, we of course hit "can't find MDIO bus for node
ethernet@2000" since indeed, the parent node of the phy node does not
represent an MDIO bus. So that's obviously the wrong path.

Now, in linux, it seems that the fixed link case is treated specially;
in the of_phy_get_and_connect() which roughly corresponds to
dm_eth_connect_phy_handle() we have

    if (of_phy_is_fixed_link(np)) {
        ret = of_phy_register_fixed_link(np);
        ...
    } else {
        phy_np = of_parse_phandle(np, "phy-handle", 0);
	...
    }

    phy = of_phy_connect(dev, phy_np, hndlr, 0, iface);

And U-Boot's phy_connect() does have support for fixed-link
subnodes. Calling phy_connect() directly with NULL bus and a dummy
address does seem to make the ethernet work.

51723c5581 net: Do not respond to ICMP_ECHO_REQUEST if we do not have an IP address
While doing DHCP the interface IP is set to 0.0.0.0. This causes the
check in net.c on dst_ip to be effectively skipped, and all IP datagrams
are accepted up the IP stack. In the case of an ICMP_ECHO_REQUEST for the
matching MAC address (regardless of destination IP), the result is that
an ICMP_ECHO_REPLY is sent. The source address of the ICMP_ECHO_REPLY is
0.0.0.0, which is an illegal source address.

This can happen in common practice with the following sequence:
DHCP (U-Boot or OS) acquires IP address 10.0.0.1
System reboots
U-Boot starts DHCP and send DHCP DISCOVER
DHCP server decides to OFFER 10.0.0.1 again
  (perhaps because of existing lease or manual configuration)
DHCP server tries to PING 10.0.0.1 to see if anyone is squatting on it
DHCP server still has our MAC address in its ARP table for 10.0.0.1
U-Boot receives PING, and responds with an illegal source address
This may further result in a the DHCP server seeing the response as
  confirmation that someone is squatting on 10.0.0.1, and picking a
  new IP address from the pool to try again

fa795f4525 net: eth-uclass: avoid running start() twice without stop()
Running the start() handler twice without a stop() inbetween completely
breaks communication for some ethernet drivers like fec_mxc.

eth_halt() is called before each eth_init(). Due to the switch to
eth_is_active() in commit 68acb51f44 ("net: Only call halt on a driver
that has been init'ed"), this is not sufficient anymore when netconsole
is active: eth_init_state_only()/eth_halt_state_only() manipulate the
state check that is performed by eth_is_active() without actually
calling into the driver.

The issue can be triggered by starting a network operation (e.g. ping or
tftp) while netconsole is active.

Add an additional "running" flag that reflects the actual state of the
driver and use it to ensure that eth_halt() actually stops the device as
it is supposed to.

e1864db60d net: sntp: remove CONFIG_TIMESTAMP constraint
CONFIG_TIMESTAMP is not related to the RTC drivers. It does not make any
sense to let the updating of the RTC by the sntp command depend on it.

Drop the CONFIG_TIMESTAMP checks.

Furthermore function dm_rtc_set() is enabled by CONFIG_DM_RTC. There is no
reason to require CONFIG_CMD_DATE when using a driver model RTC. The UEFI
sub-system can consume the RTC functions even if there is not date command.

Only check CONFIG_CMD_DATE when using a non-driver model RTC.

c8e251f82a Adds basic support for ProxyDHCP
- ProxyDHCP allows a second DHCP server to exist alongside your main
  DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
  respond with a normal response containing the new client IP address
  while simultaneously the ProxyDHCP server will respond with a blank
  client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
  enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
  (default 100) which tells u-boot to wait additional time after
  receiving the main DHCP response to give the ProxyDHCP response time
  to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
  added here as diagramed on page 16:
  http://www.pix.net/software/pxeboot/archive/pxespec.pdf:

```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option
timeouts in an attempt to receive a PXE response.
```

- Adding a simple delay worked for my purposes but let me know if a
  more robust solution is required

c3f0278e29 net: Expose some errors generated in net_init
net_init does not always succeed, and there is no existing mechanism to
discover errors. This patch allows callers of net_init (such as net_init)
to handle errors. The root issue is that eth_get_dev can fail, but
net_init_loop doesn't expose that. The ideal way to fix eth_get_dev would
be to return an error with ERR_PTR, but there are a lot of callers, and all
of them just check if it's NULL. Another approach would be to change the
signature to something like

int eth_get_dev(struct udevice **pdev)

but that would require rewriting all of the many callers.

2b2a771b40 fastboot: Add support for 'reboot fastboot' command
Android 10 adds support for dynamic partitions and in order to support
this userspace fastboot must be used[1]. New tool fastbootd is
included into recovery.

Userspace fastboot works from recovery and is launched if:
1) - Dynamic partitioning is enabled
2) - Boot control block has 'boot-fastboot' value into command field
The bootloader is expected to load and boot into the recovery image
upon seeing boot-fastboot in the BCB command. Recovery then parses the
BCB message and switches to fastbootd mode[2].

Please note that boot script is expected to handle 'boot-fastboot'
command in BCB and load into recovery mode.

Bootloader must support 'reboot fastboot' command which should reboot
device into userspace fastboot to accomodate those changes[3].

Another command that bootloader must support[3] is 'reboot recovery'. This
command should simply reboot device into recovery mode.

cc6b87ecaa net: tftp: Add client support for RFC 7440
Add support for RFC 7440: "TFTP Windowsize Option".

This optional feature allows the client and server
to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific
network topology, underlying NIC.
You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>

  typedef bd_t;
  @@
  -bd_t

one MDIO ports. So two different ethernet drivers have to share MDIO bus.
Since two ethernet drivers are independent, we can't ensure their probe
order.

To resolve this problem, introduce an eth phy generic driver and uclass.

After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.

When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the
MDIO bus will be probed before using its MDIO.

Commit b618b37076 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.

While we have networking use cases within SPL we do not support loading
files via NFS at this point in time.  Disable calling nfs_start() so
that the NFS related code can be garbage collected at link time.

fb8977c5be net: Always build the string_to_enetaddr() helper
Part of the env cleanup moved this out of the environment code and into
the net code. However, this helper is sometimes needed even when the net
stack isn't included.

Move the helper to lib/net_utils.c like it's similarly-purposed
string_to_ip(). Also rename the moved function to similar naming.

5a5d1def59 net: nfs: remove superfluous packed attribute
With GCC 9.2.1 net/nfs.c leads to multiple errors of type

struct rpc_t is only used as local variable. It is naturally packed. So
there is no need for the attribute packed.

15eea9a1a8 net: nfs: remove superfluous conversions
rpc_pkt.u.call.data is an array of uint32_t. There is no need to convert
it to uint32_t *.

memcpy() expects void * as it 1st and 2nd argument. There is no point in
converting pointers to char * before passing them to memcpy().

In ntohl(data[1]) != 0 calling ntohl() is superfluous. If the value is
zero, does not depend on the byte order.

6b3abc0482 net: mdio-uclass: name MDIO according to device-name property if preset
Use the optional property device-name to name the MDIO bus.  This works
around limitations with using the DT node name on devices such as
Armada-8040, which integrates two cp100 cores, both featuring MDIOs at the
same relative offsets and with the same DT node names.
The concept was originally proposed by Marvell as a custom property called
mdio-name specific to Marvell driver.  This patch uses the more generic
property device-name and moves this into MDIO class code so other can use
it as well.
