On certain TI SoC, like AM64x there is a CPSW3G which supports 2
external independent MAC ports for single CPSW instance.
It is not possible for Ethernet driver to register more than one port
for given instance.
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
mode and forwards all packets to host.
Since top level driver is now UCLASS_MISC, board files would need to
instantiate this driver explicitly.

Perform reset before core initialization.
Standard flow which close to 99% users are using getting all IPs out of
reset that there is no need to reset IP again. This is because of all low
level initialization is done in previous bootloader stage.
In SOM case these IPs are not touched by previous bootloader stage that's
why reset needs to be called before IP is accessed to make sure that it is
in correct state.

Xilinx DTS files are using two way how to describe ethernet phy.
The first (already supported) has phy as subnode of gem node.
eth {
phy-handle = <&phy0>;
phy0: ethernet-phy@21 {

};
The second has mdio subnode (with mdio name) which has phy subnode. This
structure allow hadling MDIO reset signal (based on Linux mdio.yaml)
eth {

This patch adds support for the second case where mdio subnode

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.

set this.
Note that the init_registers() function called from eth_ops :: start

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various

Some files did not contain any GPIO code at all, so this header was
completely unused.
A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.
The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the

GPIO_EXTRA_HEADER is no longer needed.

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.
