Currently we require PHY interface mode to be known when
finding/creating the PHY - the functions
* phy_connect_phy_id()
* phy_device_create()
* create_phy_by_mask()
* search_for_existing_phy()
* get_phy_device_by_mask()
* phy_find_by_mask()
all require the interface parameter, but the only thing done with it is
that it is assigned to phydev->interface.
This makes it impossible to find a PHY device without overwriting the
set mode.
Since the interface mode is not used during .probe() and should be used
at first in .config(), drop the interface parameter from these
functions. Make the default value of phydev->interface (in
phy_device_create()) to be PHY_INTERFACE_MODE_NA. Move the interface
parameter to phy_connect_dev(), where it should be.
Change all occurrences treewide. In occurrences where we don't call
phy_connect_dev() for some reason (they only configure the PHY without
connecting it to an ethernet controller), set
phydev->interface = value from phy_find_by_mask call.

A DM_ETH driver may use phy_connect() towards a PHY address on an MDIO
bus which is not specified in the device tree, as evidenced by:
pfe_eth_probe
-> pfe_phy_configure
-> phy_connect
When this happens, the PHY will have an invalid OF node.
When ar803x_config() runs, it silently fails at ar803x_of_init(), and
therefore, fails to run the rest of the initialization.
This makes MII_BMCR contain what it had after BMCR_RESET (0x8000) has
been written into it by phy_reset(). Since BMCR_RESET is volatile and
self-clearing, the MII_BMCR ends up having a value of 0x0. The further
configuration of this register, which is supposed to be handled by
genphy_config_aneg() lower in ar803x_config(), never gets a chance to
run due to this early error from ar803x_of_init().
As a result of having MII_BMCR as 0, the following symptom appears:
=> setenv ethact pfe_eth0
=> setenv ipaddr 10.0.0.1
=> ping 10.0.0.2
pfe_eth0 Waiting for PHY auto negotiation to complete......... TIMEOUT !
Could not initialize PHY pfe_eth0
Manually writing 0x1140 into register 0 of the PHY makes the connection
work, but it is rather desirable that the port works without any manual
intervention.

A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.
The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).
This is now handled automatically by the pinctrl driver.

Ethernet phy like dp83867 is using strapping resistors to setup PHY
address. On Xilinx boards strapping is setup on wires which are connected
to SOC where internal pull ups/downs influnce phy address. That's why there
is a need to setup pins properly (via pinctrl driver for example) and then
perform phy reset. I can be workarounded by reset gpio done for mdio bus
but this is not working properly when multiply phys sitting on the same
bus. That's why it needs to be done via ethernet-phy-id driver where dt
binding has gpio reset per phy.
DT binding is available here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet-phy.yaml
The driver is are reading the vendor and device id from valid phy node
using ofnode_read_eth_phy_id() and creating a phy device.

Some boards like the Beacon RZ/G2 SOM use either flags for

In Linux the APSR_RDM flag is set when either rx-internal-delay-ps
is set or the mode is rgmii-rxid, and the APSR_TDM is set when
tx-internal-delay-ps is found or rgmii-txid is set, and both
are set if rgmii-id is set.

Since same DT is used in Linux and U-Boot we need to workaround this
issue by using the gmii2rgmii node which points to phy and we should
ignore the gem pointing to phy directly.
Do this workaround by updating priv->phydev->node value with
priv->phy_of_node only if it is not valid node.

NXP's mEMAC reference manual, Chapter 6.5.5 "MDIO Ethernet Management
Interface usage", specifies to poll the BSY (0) bit in the CFG/STAT
register to wait until a transaction has finished, not bit 31 in the
data register.
In the Linux kernel, this has already been fixed in commit 26eee0210ad7
("net/fsl: fix a bug in xgmac_mdio").
This patch changes the register in the fman_mdio and fsl_ls_mdio
drivers.
As the MDIO_DATA_BSY define is no longer in use, this patch also removes
its definition from the fsl_memac header.

The sja1105_check_device_id() function contains logic to work without
changing the device tree on reworked boards, one of which I have (the
NXP LS1021A-TSN normally has a SJA1105T, but I have a version with a
resoldered SJA1105Q which is pin compatible). This logic is taken from
the Linux driver.
However this logic gets shortcircuited in U-Boot by an earlier check for
the exact device ID specified in the device tree. So the reworked board
does not probe the SJA1105Q switch. Remove this duplicated logic and let
the automatic device ID detection do its job.

On certain TI SoC, like AM64x there is a CPSW3G which supports 2

It is not possible for Ethernet driver to register more than one port

This patch modifies top level CPSW NUSS as UCLASS_MISC and binds
UCLASS_ETH to individual ports so as to support bring up more than one
Ethernet interface in U-Boot.
Note that there is no isolation in the since, CPSW NUSS is in promisc

Since top level driver is now UCLASS_MISC, board files would need to

Standard flow which close to 99% users are using getting all IPs out of

In SOM case these IPs are not touched by previous bootloader stage that's

The gpio_request_by_name() returns zero in case of success, however the
conditional return value check in gpio_request_by_name() checks only for
(ret != -ENOENT) and if the condition is true, returns ret outright.
This leads to a situation where successful gpio_request_by_name() return
leads to immediate successful eth_phy_of_to_plat() return as well, and
to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the
PHY driver operates with valid reset GPIO, but with assert/deassert times
set to default, which is 0, instead of the values from DT. This breaks
PHY reset.
Fix this by checking if return value is non-zero and then for this one
single allowed non-zero return value, -ENOENT.

It turns out that in custom designs if the system is reset
multiple times in conjunction with a slight increase in external
temperature, the felix switch starts to behave in a strange way:
packets are no longer received on the ENECT interface connected
to the L2switch internal port (the TX side of internal port stops working
or the packets do not reach there. It is not very clear where
the packets remain blocked. None of the counters points to a disruption
in the L2switch)
The issue is not reproducible on NXP reference designs.
It was observed that by adding the switch core reset, the problem
goes aways, even if intensive testing in temperature chambers
is applied.
The current patch performs soft reset on the switch core to ensure proper
operation of the L2switch.

The list of ports which support SGMII depending on switch generation is
available here:
https://www.kernel.org/doc/html/latest/networking/dsa/sja1105.html#port-compatibility-matrix
SGMII can either be used to connect to an external PHY or to the host
port. In the first case, the use of in-band autoneg is expected, in the
last, in-band autoneg is expected to be turned off (fixed-link). So the
driver supports both cases.
SGMII support means configuring the PCS and PMA. The PCS is a Synopsys
Designware XPCS, in Linux this has a separate driver but here it is
embedded within the sja1105 driver. If needed it can be taken out later,
although we would need a UCLASS_PCS for it, which we don't have atm.
Nonetheless, I did go all the way to export an internal MDIO bus for PCS
access, because it is nice to be able to debug the PCS through commands
such as:
=> mdio read ethernet-switch@1-pcs 4 1f.0
Reading from bus ethernet-switch@1-pcs
PHY at address 4:
31.0 - 0x1140
The internal MDIO bus is not registered with DM because there is no
udevice on it, as mentioned. But the XPCS code can still be ripped out,
as needed.
I did not add support for 2500base-x because I do not expect this
interface type to be used as a boot source for anybody, it would just
add unnecessary bloat.

The SJA1105 driver is largely reused from Linux. Its programming model
is that it is blank out of reset, and it waits for a static
configuration stream over SPI, which contains all runtime parameters (it
has no notion of "default values").
Keeping a binary array for the configuration stream would have meant
that aspects such as the CPU port and the MAC speeds could have not been
configured easily, and would have been static and board-dependent.
Live-patching the binary array means recalculating the static config
table CRCs, which is not a fun process.
So we create an abstraction over the static config tables, using the
packing API, same as in Linux. The tables are kept as C structures, and
the binary configuration stream is constructed on-the-go, with CRC and
all.
All static config tables instantiated in this driver are mandatory.
The hardware reference manual can be found at:
https://www.nxp.com/docs/en/user-guide/UM10944.pdf
For tagging, a simplified version of tag_8021q from Linux is used. The
VLAN EtherType is the same (0xdadb) but since we don't want switching in
U-Boot, there is no reason to have a TX VLAN and an RX VLAN for each
port. We just need the RX VLANs to act as the unique pvid of each
front-panel port, to decode the switch port number. The RX VLAN is used
for both RX and TX.
The device tree bindings are the same as in Linux.
