Linux displays the real PCIe card connected to a mvebu PCIe slot as
device 0, not 1. This is done by setting local dev number to 1, so that
the local "Marvell Memory controller" device is on address 1.
Let's do it also in U-Boot.
With this commit the pci command in U-Boot prints something like:

Refactor validation of bdf parameter in mvebu_pcie_read/write_config
functions.
We can simplify the code by putting the validation into separate
function.
Also there are always only two devices visible on local bus:
* on slot configured by function mvebu_pcie_set_local_dev_nr()
(by default this register is set to 0) there is a
"Marvell Memory controller", which isn't useful in root complex
mode,
* on all other slots the real PCIe card connected to the PCIe slot.
We can simplify the code even more by simply allowing access only to
the real PCIe card.

The NOR flash w25q128 denoted by JEDEC ID 0xef4018 actually represents

w25q128bv_revh_100313_wo_automotive.pdf
According to the datasheets, all of these 3 types support BP(0,1,2) and

If zynqmp_qspi_set_speed() is called multiple times with the same speed,
then on the second call it will skip recalculating the baud_rate_val as
it assumes the speed is already configured correctly. But it will still
write the baud_rate_val to the configuration register and call
zynqmp_gqspi_set_tapdelay(). Because it skipped recalculating the
baud_rate_val, it will use the initial value of 0 . This causes the
driver to run at maximum speed which for many spi flashes is too fast and
causes data corruption.
Instead only write out a new baud_rate_val if we have calculated the
correct baud_rate_val.
This opens up another issue with the "if (speed == 0)", we don't save
off the new plat->speed_hz value when setting the baud rate on the
speed=0 path. Instead mimic what the Linux zynqmp gqspi driver does, and
have speed==0 just use the same calculation as a normal speed. That will
cause the baud_rate_val to use the slowest speed possible, which is the
safest option.

new feature:
- Allow disabling driver model for I2C in SPL
fixes:
- i2c-gpio: Fix GPIO output
- at91: fix crash when using 'i2c probe'
Use CONFIG_IS_ENABLED() macro, which provides more convenient
way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs
for both SPL and U-Boot proper.
CONFIG_IS_ENABLED(DM_I2C) expands to:
- 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y',
- 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y',
- 0 otherwise.
All occurences were replaced automatically using these bash cmds:
$ find . -type f -exec sed -i

adjusting some drivers.
This patch introduces a separate Kconfig symbols for enabling DM_I2C and
DM_I2C_GPIO support in SPL.
This will also help to get away from dirty workarounds to

After command is sent and before card response shows up on the line,
there is a variable number of clock cycles in between called Ncr.
The spec [1] says the minimum is 1 byte and the maximum is 8 bytes.
Current logic in mmc_spi_sendcmd() has a flaw that it could only work
with certain SD cards with their Ncr being just 1 byte.
When resp_match is false, the codes try to receive only 1 byte from
the SD card. On the other hand when resp_match is true, the logic
happens to be no problem as it loops until timeout to receive as many
bytes as possible to see a match of the expected resp_match_value.
However not every call to mmc_spi_sendcmd() is made with resp_match
being true hence this exposes a potential issue with SD cards that
have a larger Ncr value.
Given no issue was reported as of today, we can reasonably conclude
that all cards being used on the supported boards happen to have a 1
byte Ncr timing requirement. But a broken case can be triggered by
utilizing QEMU to emulate a larger value of Ncr (by default 1 byte
Ncr is used on QEMU). This commit fixes such potential spec violation
to improve the card compatibility.

So far we've assumed a fixed configuration for inbound windows as we had
a single user for this controller. But the controller's DMA constraints
were improved starting with BCM2711's B1 revision of the SoC, notably
available in CM4 and Pi400. They allow for wider inbound windows. We can
now cover the whole address space, whereas before we where limited to
the lower 3GB.
This information is passed to us through DT's 'dma-ranges' property and
it's specially important for us to honor it since some interactions with
the board's co-processor assume we're doing so (specifically the XHCI
firmware load operation, which is handled by the co-processor after

This driver is used for the Ethernet switch integrated into LS1028A NXP.
Felix on LS1028A has 4 front panel ports and two internal ports, I/O
to/from the switch is done through an ENETC Ethernet interface.
The 4 front panel ports are available as Ethernet interfaces and can be
used with the typical network commands like tftp.

DSA stands for Distributed Switch Architecture and it covers switches that
are connected to the CPU through an Ethernet link and generally use frame
tags to pass information about the source/destination ports to/from CPU.
Front panel ports are presented as regular ethernet devices in U-Boot and
they are expected to support the typical networking commands.
DSA switches may be cascaded, DSA class code does not currently support
this.

The DSA (Distributed Switch Architecture) implementation has made a
design decision when it got introduced to the Linux kernel in 2008.
That was to hide away from the user the CPU-facing Ethernet MAC, since
it does not make sense to register it as a struct net_device (UCLASS_ETH
udevice for U-Boot), because that would never be beneficial for a user:
they would not be able to use it for traffic, since conceptually, a
packet delivered to the CPU port should loop back into the system.
Nonetheless, DSA has had numerous growing pains due to the lack of a
struct net_device for the CPU port, but so far it has overcome them.
It is unlikely at this stage of maturity that this aspect of it will
change.
We would like U-Boot to present the same information as Linux, to be at
parity in terms of number of interfaces, so that ethNaddr environment
variables could directly be associated between U-Boot and Linux.
Therefore, we would implicitly like U-Boot to hide the CPU port from the
user as well.
But the paradox is that DSA still needs a struct phy_device to inform
the driver of the parameters of the link that it should configure the
CPU port to. The problem is that the phy_device is typically returned
via a call to phy_connect, which needs an udevice to attach the PHY to,
and to search its ofnode for the 'fixed-link' property. But we don't
have an udevice to present for the CPU port.
Since 99% of DSA setups are MAC-to-MAC connections between the switch
and the host Ethernet controller, the struct phy_device is going to be a
fixed PHY. This simplifies things quite a bit. In U-Boot, a fixed PHY
does not need an MDIO bus, and does not need an attached dev either.
Basically, the phy_connect call doesn't do any connection, it just
creates the fixed PHY.
The proposal of this patch is to introduce a new fixed_phy_create
function which will take a single argument: the ofnode that holds this:
port@4 {
reg = <4>;
phy-mode = "internal";
fixed-link {
speed = <2500>;
full-duplex;
};
};
and probe a fixed PHY driver using the information from this ofnode.
DSA will probably be the only user of this function.

Unlike the Linux fixed PHY driver, the one in U-Boot does not attempt to
emulate the clause 22 register set of a gigabit copper PHY driver
through the swphy framework. Therefore, the limitation of being unable
to support speeds higher than gigabit in fixed-link does not apply to
the U-Boot fixed PHY driver. This makes the fixed-link U-Boot
implementation more similar to the one from phylink, which can work with
any valid link speed.

At present this function does not accept a size for the FIT. This means
that it must be read from the FIT itself, introducing potential security
risk. Update the function to include a size parameter, which can be
invalid, in which case fit_check_format() calculates it.
For now no callers pass the size, but this can be updated later.
Also adjust the return value to an error code so that all the different
types of problems can be distinguished by the user.

pin-controller pin's name must be equal to pin's name used in device

Whereas in stmfx pin-controller driver, pin's name are equal to

This lead to not configure stmfx's pins at probe because pins is
