12662e7034 firmware: zynqmp: Move loading message to debug
Power domain driver is using this function for every IP which is PD listed.
This can end up with a lot of messages which end up in boot log. That's why
show it only in EL3 as was used in past.

	power-domains = <0x0c 0x1e>;
	clocks = <0x03 0x1f 0x03 0x69 0x03 0x2e 0x03 0x32 0x03 0x2c>;

	phy-mode = "gmii";
	xlnx,ptp-enet-clock = <0x00>;
	local-mac-address = [ff ff ff ff ff ff];
	phandle = <0x4d>;

	mdio {
		#address-cells = <0x01>;
		#size-cells = <0x00>;
		phandle = <0x4e>;

		ethernet-phy@1 {
			reg = <0x01>;
			rxc-skew-ps = <0x708>;
			txc-skew-ps = <0x708>;
			phandle = <0x0e>;
		};

		gmii_to_rgmii_0@8 {
			compatible = "xlnx,gmii-to-rgmii-1.0";
			phy-handle = <0x0e>;
			reg = <0x08>;
			phandle = <0x4f>;
		};
	};
};

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.

f44bcb9f0d nand: gpmc: Handle bitflips in erased pages when using BCH ECC engine
In the case of an erased (sub)page both the data and ECC are all 0xFF
bytes. This fails the normal ECC verification, as the computed ECC of
all-0xFF is not also 0xFF. The GPMC NAND driver attempted to detect
erased pages by checking that the ECC bytes are all-0xFF, but this had
two problems:
1) bitflips in the data were not corrected, so the data looked not-erased
2) bitflips in the ECC bytes were reported as uncorrectable ECC errors

The equivalent Linux driver [1] correctly handles this by counting the
number of 0-bits in the combination of data and ECC bytes. If the number
of 0-bits is less than the amount of bits correctable by the selected
ECC algorithm, then it is treated as an erased page with correctable
bitflips.

Implement similar, though simplified, logic in omap_correct_data_bch().

See AM437x Reference Manual in section 27 QSPI >> 27.2 Integration.

eab18b3b06 net: fsl: Fix busy flag polling register

This patch changes the register in the fman_mdio and fsl_ls_mdio

The sja1105_check_device_id() function contains logic to work without

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.

This patch modifies top level CPSW NUSS as UCLASS_MISC and binds

Ethernet interface in U-Boot.

Note that there is no isolation in the since, CPSW NUSS is in promisc

226fce6108 phy: Track power-on and init counts in uclass
On boards using the RK3399 SoC, the USB OHCI and EHCI controllers share
the same PHY device instance. While these controllers are being stopped
they both attempt to power-off and deinitialize it, but trying to
power-off the deinitialized PHY device results in a hang. This usually
happens just before booting an OS, and can be explicitly triggered by
running "usb start; usb stop" in the U-Boot shell.

Implement a uclass-wide counting mechanism for PHY initialization and
power state change requests, so that we don't power-off/deinitialize a
PHY instance until all of its users want it done. The Allwinner A10 USB
PHY driver does this counting in-driver, remove those parts in favour of
this in-uclass implementation.

The sandbox PHY operations test needs some changes since the uclass will
no longer call into the drivers for actions matching its tracked state
(e.g. powering-off a powered-off PHY). Update that test, and add a new
one which simulates multiple users of a single PHY.

The major complication here is that PHY handles aren't deduplicated per
instance, so the obvious idea of putting the counts in the PHY handles
don't immediately work. It seems possible to bind a child udevice per
PHY instance to the PHY provider and deduplicate the handles in each
child's uclass-private areas, like in the CLK framework. An alternative
approach could be to use those bound child udevices themselves as the
PHY handles. Instead, to avoid the architectural changes those would
require, this patch solves things by dynamically allocating a list of
structs (one per instance) in the provider's uclass-private area.

a398a51ccc pci: Work around PCIe link training failures
Attempt to handle cases with a downstream port of a PCIe switch where
link training never completes and the link continues switching between
speeds indefinitely with the data link layer never reaching the active
state.

It has been observed with a downstream port of the ASMedia ASM2824 Gen 3
switch wired to the upstream port of the Pericom PI7C9X2G304 Gen 2
switch, using a Delock Riser Card PCI Express x1 > 2 x PCIe x1 device,
P/N 41433, wired to a SiFive HiFive Unmatched board.  In this setup the
switches are supposed to negotiate the link speed of preferably 5.0GT/s,
falling back to 2.5GT/s.

However the link continues oscillating between the two speeds, at the
rate of 34-35 times per second, with link training reported repeatedly
active ~84% of the time, e.g.:

Forcibly limiting the target link speed to 2.5GT/s with the upstream
ASM2824 device makes the two switches communicate correctly however:

Make use of this observation then and attempt to detect the inability to
negotiate the link speed automatically, and then handle it by hand.  Use
the Data Link Layer Link Active status flag as the primary indicator of
successful link speed negotiation, but given that the flag is optional
by hardware to implement (the ASM2824 does have it though), resort to
checking for the mandatory Link Bandwidth Management Status flag showing
that the link speed or width has been changed in an attempt to correct
unreliable link operation (the ASM2824 does set it too).

If these checks indicate that link may not operate correctly, then poll
the Data Link Layer Link Active status flag along with the Link Training
flag for the duration of 200ms to see if the link has stabilised, that
is either that the Data Link Layer Link Active status flag has been set
or that Link Training has been inactive during at least the second half
of the interval.

If that has indicated failure, restrict the target speed to 2.5GT/s,
request a link retrain and check again if the link has stabilised.  If
that does not work either, then restore the original speed setting and
claim defeat, otherwise we are done.

NB interestingly enough with the ASM2824 vs PI7C9X2G304 configuration
referred above asking the ASM2824 to retrain with a higher target link
speed once the 2.5GT/s speed has been negotiated makes the two devices
successfully negotiate 5.0GT/s.  Lifting the 2.5GT/s speed restriction
would however prevent our workaround from working with an OS that issues
a reset and that is unaware of the problem.  This is because the devices
would then try to negotiate a higher link speed from scratch and fail,
while the sticky property of the Target Link Speed setting will keep the
2.5GT/s speed restriction across a reset.

Keep the 2.5GT/s speed restriction then, conservatively, if functional
once applied.

3fc92a215b ddr: marvell: a38x: fix SPLIT_OUT_MIX state decision
This is a cleaned up and fixed version of a patch
  mv_ddr: a380: fix SPLIT_OUT_MIX state decision

  in each pattern cycle the bus state can be changed
  in order to avoide it, need to back to the same bus state on each
  pattern cycle
by
  Moti Boskula <motib@marvell.com>

The original patch is not in Marvell's mv-ddr-marvell repository. It was
gives to us by Marvell to fix an issues with DDR training on some
boards, but it cannot be applied as is to mv-ddr-marvell, because it is
a very dirty draft patch that would certainly break other things, mainly
DDR4 training code in mv-ddr-marvell, since it changes common functions.

I have cleaned up the patch and removed stuff that seemed unnecessary
(when removed, it still fixed things). Note that I don't understand
completely what the code does exactly, since I haven't studied the DDR
training code extensively (and I suspect that no one besides some few
people in Marvell understand the code completely).

Anyway after the cleanup the patch still fixes isssues with DDR training
on the failing boards.

There was also a problem with the original patch on some of the Allied
Telesis' x530 boards, reported by Chris Packham. I have asked Chris to
send me some logs, and managed to fix it:
- if you look at the change, you'll notice that it introduces
  subtraction of cur_start_win[] and cur_end_win[] members, depending on
  a bit set in the current_byte_status variable
- the original patch subtracted cur_start_win[] if either
  BYTE_SPLIT_OUT_MIX or BYTE_HOMOGENEOUS_SPLIT_OUT bits were set, but
  subtracted cur_end_win[] only if the first one (BYTE_SPLIT_OUT_MIX)
  was set
- from Chris Packham logs I discovered that the x530 board where the
  original patch introduced DDR training failure, only the
  BYTE_HOMOGENEOUS_SPLIT_OUT bit was set, and on our boards where the
  patch is needed only the BYTE_SPLIT_OUT_MIX is set in the
  current_byte_status variable
- this led me to the hypothesis that both cur_start_win[] and
  cur_end_win[] should be subtracted only if BYTE_SPLIT_OUT_MIX bit is
  set, the BYTE_HOMOGENEOUS_SPLIT_OUT bit shouldn't be considered at all
- this hypothesis also gains credibility when considering the commit
  title ("fix SPLIT_OUT_MIX state decision")

Hopefully this will fix things without breaking anything else.

eadc4f512f ddr: marvell: a38x: Fix Synchronous vs Asynchronous mode determination
Before commit 4c289425752f ("mv_ddr: a38x: add support for ddr async
mode"), Asynchornous Mode was only used when the CPU Subsystem Clock
Options[4:0] field in the SAR1 register was set to value 0x13: CPU at
2 GHz and DDR at 933 MHz.

Then commit 4c289425752f ("mv_ddr: a38x: add support for ddr async
mode") added support for Asynchornous Modes with frequencies other than
933 MHz (but at least 467 MHz), but the code it added to check for
whether Asynchornous Mode should be used is wrong: it checks whether the
frequency setting in board DDR topology map is set to value other than
MV_DDR_FREQ_SAR.

Thus boards which define a specific value, greater than 400 MHz, for DDR
frequency in their board topology (e.g. Turris Omnia defines
MV_DDR_FREQ_800), are incorrectly put into Asynchornous Mode after that
commit.

The A38x Functional Specification, section 10.12 DRAM Clocking, says:
  In Synchornous mode, the DRAM and CPU clocks are edge aligned and run
  in 1:2 or 1:3 CPU to DRAM frequency ratios.

Change the check for whether Asynchornous Mode should be used according
to this explanation in Functional Specification.

c03f4da187 mtd: nand: pxa3xx: use marvell, prefix for custom DT properties
The DT properties for the "enable-arbiter" and "keep-config" config
knobs were previously named inconsistently:

- The u-boot driver used "nand-enable-arbiter" and "nand-keep-config"
  names, without Marvell prefixes.

- The Linux driver uses "marvell,nand-keep-config" ("enable-arbiter"
  does not exist anymore in recent kernels, but it also used to be
  "marvell,nand-enable-arbiter").

- The device trees almost all use "marvell," prefixed names, except for
  one single instance of "nand-enable-arbiter" without vendor prefix.

This commit standardizes on the vendor prefixed version, making the
u-boot driver read from DT props "marvell,nand-enable-arbiter" and
"marvell,nand-keep-config". The one device tree using the unprefixed
version is also changed to use the new naming.

This has the side effect of making the previously no-op "marvell,"
config knobs already present in some DTs actually do something. This was
likely the original intention of the DT authors, but note that this
commit was not tested on every single impacted board.

94c30f9c8f arm: mvebu: a38x: serdes: Move non-serdes PCIe code to pci_mvebu.c
As explained in commit 3bedbcc3aa ("arm: mvebu: a38x: serdes: Don't
overwrite read-only SAR PCIe registers") it is required to set Maximum Link
Width bits of PCIe Root Port Link Capabilities Register depending of number
of used serdes lanes. As this register is part of PCIe address space and
not serdes address space, move it into pci_mvebu.c driver.

Read number of PCIe lanes from DT property "num-lanes" which is used also
by other PCIe controller drivers in Linux kernel. If this property is
absent then it defaults to 1. This property needs to be set to 4 for every
mvebu board which use PEX_ROOT_COMPLEX_X4 or PEX_BUS_MODE_X4.

Enabling of PCIe port needs to be done afer all registers in PCIe address
space are properly configure. For this purpose use new mvebu-reset driver
(part of system-controller) and remove this code from serdes code.

Because some PCIe ports cannot be enabled individually, it is required to
first setup all PCIe ports and then enable them.

This change contains also all required "num-lanes" and "resets" DTS
properties, to make pci_mvebu.c driver work correctly.

e7ff4271ab pci: pci_mvebu: Wait 100ms for Link Up in mvebu_pcie_probe()
After function mvebu_pcie_probe() returns U-Boot DM expects that PCIe link
is already up. In followup patches link initialization will be moved from
SPL to proper and therefore explicitly link up delay is required.

Delay mvebu_pcie_probe() for 100ms to ensure that PCIe link is up after
function finish. In the case when no card is connected to the PCIe slot,
this will delay probe time by 100ms, which should not be problematic.

This change fixes detection and initialization of some QCA98xx cards on
the first serdes when configured in x1 mode. Default configuration of
the first serdes on A385 is x4 mode, so it looks as if some delay is
required when x4 is changed to x1 and card correctly links with A385.
Other PCIe serdes ports on A385 are x1-only, and so they don't have this
problem.

537b0142b0 pci: pci_mvebu: Fix PCIe MEM and IO resources assignment and mbus mapping
Do not call pci_set_region() for resources which were not properly mapped.
This prevents U-Boot to access unmapped memory space.

Update MBUS_PCI_MEM_SIZE and MBUS_PCI_IO_SIZE macros to cover all PCIe MEM
and IO ranges. Previously these macros covered only address ranges for the
first PCIe port. Between MBUS_PCI_IO_BASE and MBUS_PCI_MEM_BASE there is
space for six 128 MB long address ranges. So set MBUS_PCI_MEM_SIZE to value
of 6*128 MB. Similarly set MBUS_PCI_IO_SIZE to 6*64 KB.

Function resource_size() returns zero when start address is 0 and end
address is -1. So set invalid resources to these values to indicate that
resource has no mapping.

Split global PCIe MEM and IO resources (defined by MBUS_PCI_*_* macros)
into PCIe ports in mvebu_pcie_bind() function which allocates per-port
based struct mvebu_pcie, instead of using global state variables
mvebu_pcie_membase and mvebu_pcie_iobase. This makes pci_mvebu.c driver
independent of global static variables (which store the state of
allocation) and allows to bind and unbind the driver more times.

b2acee4bb0 mmc: fsl_esdhc_imx: set sysctl register for clock initialization
[ fsl_esdhc commit 263ddfc345 ]

The initial clock setting should be through sysctl register only,
while the mmc_set_clock() will call mmc_set_ios() introduce other
configurations like bus width, mode, and so on.

00e0cd7fda mmc: fsl_esdhc_imx: Replace more #ifdefs by if
This builds on the previous patch by converting yet more preprocessor
macros to C ifs. This is split off so that the changes adapted from
Micheal's patch may be clearly distinguished from the ones I have
authored myself.

MMC_SUPPORTS_TUNING should really get a Kconfig conversion. And DM_GPIO
needs some -ENOSYS stubs when it isn't defined.

95d6b74cf8 mmc: fsl_esdhc_imx: clean up bus width configuration code
[ fsl_esdhc commit 07bae1de38 ]

This patch is to clean up bus width setting code.

- For DM_MMC, remove getting "bus-width" from device tree.
  This has been done in mmc_of_parse().

- For non-DM_MMC, move bus width configuration from fsl_esdhc_init()
  to fsl_esdhc_initialize() which is non-DM_MMC specific.
  And fix up bus width configuration to support only 1-bit, 4-bit,
  or 8-bit. Keep using 8-bit if it's not set because many platforms
  use driver without providing max bus width.

- Remove bus_width member from fsl_esdhc_priv structure.

This reverts commit 92f1e9a4b3.
The aforementioned patch causes massive breakage on all platforms which
have 'assigned-clock' DT property in their DT which references any clock
that are not supported by the platform clock driver. That can easily
happen either in SPL, or because the clock driver is reduced. Currently
it seems all iMX8M are affected and fail to boot altogether.

         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 {
