be7dbb60c5 Convert CONFIG_SYS_IMMR to Kconfig
This converts the following to Kconfig:
   CONFIG_SYS_IMMR

We do this by consolidating the SYS_IMMR options we have and providing
defaults.

We also, in the few places where M68K was also sharing code with these
platforms, define it within the file to CONFIG_SYS_MBAR to match usage.
This should be cleaned up longer term.

This converts the following to Kconfig:
   CONFIG_ENV_SPI_BUS
   CONFIG_ENV_SPI_CS
   CONFIG_ENV_SPI_MAX_HZ
   CONFIG_ENV_SPI_MODE

As part of this, we use Kconfig to provide the defaults now that were
done in include/spi_flash.h.  We also in some cases change from using
CONFIG_ENV_SPI_FOO to CONFIG_SF_DEFAULT_FOO as those were the values in
use anyhow as ENV was not enabled.

The watchdog system reset driver can reboot the device but it cannot power
it off. If power off is requested, the driver should not reset the system
but leave powering off to one of the other system reset drivers.

As power cycling is typically not a feature of a watchdog driver the reset
types SYSRESET_POWER and SYSRESET_POWER_OFF shall both be excluded.

Function mvebu_pcie_setup_wins() sets up all other BARs, so move setup of
BAR[0] to this function to have common code at one place.

In the past, commit 193a1e9f19 ("pci: pci_mvebu: set BAR0 after memory
space is set") moved setup of BAR[0] to another location, due to ath10k
not working in kernel, but the reason why was unknown, but it seems to
work now, and we think the issue then was cause by the PCIe Root Port
presenting itself as a Memory Controller and therefore U-Boot's code
have overwritten the BAR. Since the driver now ignores any write
operations to PCIe Root Port BARs, this should not be an issue anymore.

d8063dc373 efi: Add a media/block driver for EFI block devices
Add a block driver which handles read/write for EFI block devices. This
driver actually already exists ('efi_block') but is not really suitable
for use as a real U-Boot driver:

- The operations do not provide a udevice
- The code is designed for running as part of EFI loader, so uses
    EFI_PRINT() and EFI_CALL().
- The bind method probes the device, which is not permitted
- It uses 'EFI' as its parent device

The new driver is more 'normal', just requiring its platform data be set
up in advance.

8777033722 net: eth-phy: Handle gpio_request_by_name() return value
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.

8c1a6957b1 drivers: net: Soft reset felix switch core
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.

5db5815e99 serial: a37xx: Reset whole UART when changing parent clock from TBG to XTAL
Sometimes UART stops transmitting characters after UART clock is changed
back to XTAL. In this state UART fifo is always full. Kernel during early
boot wants to print output on UART and is waiting for non-empty UART fifo.
Which leads to CPU hangup without any (debug) output on UART.

Marvell Armada 3700 Functional Specifications says that for programming
fractional divisor registers it is required to disable UART, enable
loopback mode, reset fifos, program registers, disable loopback mode,
release reset of fifos and enable UART.

But these steps do not fix above mentioned issue that UART hangup. Also
gating UART clock does not help. And even resetting UART state machines do
not help.

Experiments showed that UART fifo is unblocked after board is being reset
(during board reset UART HW transmit UART fifo even CPU is not executing
kernel/bootloader anymore).

And another experiments showed that same workaround can be achieved also
by external reset of UART HW (without need to reset board).

So do not implement any of "Marvell recommended" steps from Functional
Specifications as they do not work. And rather prior changing parent clock
back to XTAL, do external reset of UART HW. This operation also resets all
UART registers, so basically it also sets UART clock to default, which is
XTAL. It is unknown why UART hangups and enters such broken state.

This method is currently called after the platform data has been freed.
But the pre_unbind() method may wish to access this, e.g. to free some
data structures stored there.

Split the unbinding of devices into two pieces, as is done with removal.
This corrects the problem.

48108f3a6a firmware: scmi: Add OP-TEE transport
This change implements an SCMI transport for agent interfacing the
OP-TEE SCMI service. OP-TEE provides an SCMI PTA (Pseudo-TA) for
non-secure world to send SCMI messages over an identified channel.
The driver implemented here uses a SMT shared memory for passing
messages between client and server.

The implementation opens and releases channel resources for each
passed SCMI message so that resources allocated (sessions) or
registered (shared memory areas) in OP-TEE firmware are released for
example before relocation as the driver will likely allocate/register
them back when probed after relocation.

The integration of the driver using dedicated config switch
CONFIG_SCMI_AGENT_OPTEE is designed on the model posted to the
U-Boot ML by Patrick Delaunay [1].

In Linux commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx

Copy the logic from linux, so the delay config is set from the PHY's

This removes the need for a one-off workaround for the Pine A64+ board.

7f7e73eee3 net: dsa: sja1105: add support for SGMII
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.

f24b666b22 net: dsa: add driver for NXP SJA1105 L2 switch
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.

2dd6acb795 net: introduce a helper to determine whether to use in-band autoneg
Certain serial SERDES protocols like 1000base-x, 2500base-x, SGMII,
USXGMII can operate either in a mode where the PHY (be it on-board or
inside an SFP module) passes the link parameters (speed, duplex, pause)
to the MAC through in-band through control words standardized by IEEE
802.3 clause 37, or in a mode where the MAC must configure (force) its
link parameters based on information obtained out-of-band (MDIO reads,
guesswork etc).

In Linux, the OF node property named "managed" is parsed by the phylink
framework, and the convention is that if a driver uses phylink, then the
presence of this property means that in-band autoneg should be enabled,
otherwise it shouldn't.

To be compatible with the OF node bindings of drivers that use phylink
in Linux, introduce parsing support for this property in U-Boot too.

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

This regression is seen during mmc_init and caused by the following

Indeed since we did not support poll dat0, we fulfilled the condition
of [1] and a delay of 500 ms was added for every __mmc_switch call.

By adding the support of wait_dat0(), we now don't need to mdelay

Lot of PCIe controllers are using ECAM addressing. So add common ECAM

Replace custom ECAM address macros in every PCI controller driver by new
ECAM macros from U-Boot's pci.h header file.

Similar macros are defined also in Linux kernel. There is a small
difference between Linux and these new U-Boot macros.

U-Boot's PCIE_ECAM_OFFSET() takes device and function numbers in separate
arguments. Linux's PCIE_ECAM_OFFSET() takes device and function numbers
encoded in one argument. The reason is that U-Boot's PCI_DEVFN() macro is

Without get_desc, the tpm command will not provide a
description of the device in 'tpm device' or 'tpm info'.

Due to the characteristics of the Atmel TPM it isn't
possible to determine certain attributes (e.g open/close
status) without using the TPM stack (compare Infineon
and ST TPM drivers), so just print out the chip model
and udevice name as the identifier.

This patch also simplifies the code in cpu.c, stm32mp1_ram.c and
clk_stml32mp1.c as execution of U-Boot in sysram (boot without SPL and
without TFA) is not supported: the associated initialization code is
present only in SPL.

This cleanup patch is a preliminary step to support SPL load of OP-TEE
in secure world, with SPL in secure world and U-Boot in no-secure world.

2b0b51d0be usb: dwc3: add layerscape support
Add support for the proper dwc3 device tree binding support as specified
in the offical device tree spec.

Initially, add support for the LS1028A support. Other SoCs should be
easy to add by just adding the corresponding compatible string.
Unfortunately, the device trees of all other layerscape SoCs are not
converted and uses a wrong compatible string only known in u-boot.

To maintain backwards compatibility with current u-boot device trees,
add the generic "fsl,layerscape-dwc3" compatible string.

OTG mode is not supported yet. The dr_mode in the devicetree will either
have to be set to peripheral or host.

cde9b147ba scsi: ceva: rename the resource name to match the linux kernel one
The driver will look for a named resource "ecc-addr", but this isn't the
official binding. In fact, the official device tree binding
documentation doesn't mention any resource names at all. But it is safe
to assume that it's the linux ones we have to use if we want to be
compatible with the linux device tree. Thus rename "ecc-addr" to
"sata-ecc" and convert all the users in u-boot.

While at it, also rename "sata-base" to "ahci" although its not used at
all.

This change doesn't affect the SATA controller on the ZynqMP.

1834c081d3 efi: Add video support to the app
The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.

The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.

Enable video output for the app. Note that this uses the
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa.

A sample qemu command-line for this case is:

   qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd

57fa6fb932 arm: a37xx: pci: Program the data strobe for config read requests
According to the Armada 3720 Functional Specification Data Strobe applies
for both read and write config requests.

Data strobe bits configure which bytes from the start address should be
returned for read request. Set value 0xf (all 4 bits) into Data Strobe
register to read all four bytes from specified 32-bit config space
register. Same value for Data Strobe register is programmed by Linux
pci-aardvark.c driver for config read requests.

Without this patch pci-aardvark driver sets data strobe register only
during config write operations. So any followup config read operations
could result with just partial datai returned (if previous write operation
was not 32-bit wide). This patch fixes it and ensures that config read
operations always read all bytes from requested register.

a7b61ab58d pci: pci_mvebu: Properly configure and use PCI Bridge (PCIe Root Port)
The mysterious "Memory controller" PCI device which is present in PCI
config space is improperly configured and crippled PCI Bridge which acts
as PCIe Root Port for endpoint PCIe card.

This PCI Bridge reports in PCI config space incorrect Class Code (Memory
Controller) and incorrect Header Type (Type 0). It looks like HW bug in
mvebu PCIe controller but apparently it can be changed via mvebu registers
to correct values.

The worst thing is that this PCI Bridge is crippled and its PCI config
registers in range 0x10-0x34 alias access to internal mvebu registers which
have different functionality as PCI Bridge registers. Moreover,
configuration of PCI primary and secondary bus numbers (registers 0x18
and 0x19) is done via totally different mvebu registers via totally strange
method and cannot be done via PCI Bridge config space.

Due to above fact about PCI config range 0x10-0x34, allocate a private
cfgcache[] buffer in the driver, to which PCI config access requests to
the 0x10-0x34 space will be redirected in mvebu_pcie_read_config() and
mvebu_pcie_write_config() functions. Function mvebu_pcie_write_config()
will also catch writes to PCI_PRIMARY_BUS (0x18) and PCI_SECONDARY_BUS
(0x19) registers and set PCI Bridge primary and secondary bus numbers via
mvebu's own method.

Also, Expansion ROM Base Address register (0x38) is available, but at
different offset 0x30. So recalculate register offset before accessing PCI
config space.

After these steps U-Boot sees working PCI Bridge and CONFIG_PCI_PNP code
can finally start enumerating all PCIe devices correctly, even with more
complicated PCI topology. So update also mvebu_pcie_valid_addr() function
to reflect state of the real device topology.

Each PCIe port is de-facto isolated and every PCI Bridge which is part of
PCIe Root Complex is also isolated, so put them on separate PCI buses as
(local) device 0.

U-Boot already supports enumerating separate PCI buses, real (HW) bus
number can be retrieved by "PCI_BUS(bdf) - dev_seq(bus)" code, so update
config read/write functions to properly handle more complicated tree
topologies (e.g. when a PCIe switch with multiple PCI buses is connected
to the PCIe port).

Local bus number and local device number on mvebu are used for determining
which config request type is used (Type 0 vs Type 1). On normal non-broken
PCIe hardware it is done by primary and secondary bus numbers. So correctly
translate settings between these numbers to ensure that correct config
requests are sent over the PCIe bus.

As bus numbers are correctly re-configured, it does not make sense to print
some initial bogus configuration during probe, so remove this debug code.

When reading 8 or 16 bits from config space, use appropriate readb() or

from endpoint card as asked by read_config() function.

Technically there should not be an issue with reading data from config
space which are not later used as there are no clear-by-read registers.
But it is better to use correct read operation based on requested size.
