At the moment, the U-Boot serial_msm driver does not initialize the
UART_DM_DMEN register with the required value. Usually this does not
cause any problems, because there is Qualcomm's LK bootloader running
before U-Boot which initializes the register with the correct value.
It's important that this register is initialized correctly, because
the U-Boot driver does not make use of the BAM/DMA or single character
mode functionality of the UART controller. A different bootloader
before U-Boot might initialize the register differently.
For example, on DragonBoard 410c U-Boot can also be installed to the
"aboot" partition (replacing LK entirely). In this case U-Boot is
loaded directly by SBL, which seems to use the single-character mode
for some reason. In single character mode there is always just one
char in the FIFO, instead of the 4 characters expected by
msm_serial_fetch(). It also causes issues with "earlycon" later in
the Linux kernel, which tries to output 4 chars at once,
but only the first char will be written.
This causes early UART log in Linux to be corrupted like this:
[ 00ano:ameoi .Q1B[ 00ac _idaM00080oo'ahani-lcle._20). 15NdNii 5 SPMSJ20:U2
[ 00rkoolmsamel
[ 00Fw ]elamletopsioble

instead of

[ 0.000000] printk: bootconsole [msm_serial_dm0] enabled
Make sure to initialize UART_DM_DMEN correctly to fix this issue
when loading U-Boot directly after SBL (instead of through LK).
There is no functional difference when loading U-Boot through LK
since LK also initializes UART_DM_DMEN to 0x0. [1]

This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple

the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.
This emulated PWM device is then used to test the Chromium OS PWM driver

The RGMII spec supports optional in-band status reporting for the speed

this feature by default.
However, this does not work when the PHY does not implement the in-band
reporting, or when there is a MAC-to-MAC connection described using a
fixed-link. In that case, it would be better to disable the feature in
the ENETC MAC and always force the speed and duplex to the values that
were negotiated and retrieved over MDIO once the autoneg is finished.
Since this works always, we just do it unconditionally and drop the
in-band code.
Note that because we need to wait for the autoneg to complete, we need
to move enetc_setup_mac_iface() after phy_startup() returns, and then
pass the phydev pointer all the way to enetc_init_rgmii().
The same considerations have led to a similar Linux driver patch as well:

When the flash is handed to us in a stateful mode like 8D-8D-8D, it is
difficult to detect the mode the flash is in. One option is to read SFDP
in all modes and see which one gives the correct "SFDP" signature, but
not all flashes support SFDP in 8D-8D-8D mode.
Further, even if you detect the mode of the flash via SFDP, you still
have the problem of actually reading the ID. The Read ID command is not
standardized across flash vendors. Flashes can have different dummy
cycles needed for reading the ID. Some flashes even expect a 4-byte
dummy address with the Read ID command. All this information cannot be
obtained from the SFDP table.
So, perform a Software Reset sequence before reading the ID and
initializing the flash. A Soft Reset will bring back the flash in its
default protocol mode assuming no non-volatile configuration was set.
This will let us detect the flash even if ROM hands it to us in Octal
DTR mode.
To accommodate cases where there is more than one flash on a board, and
only one of them needs a soft reset, failure to reset is not made fatal,
and we still try to read ID if possible.

fail to detect the flash.
So, we need to reset to Power-on-Reset (POR) state before handing off
the flash. A Software Reset command can be used to do this.
One limitation of the soft reset is that it will restore state from
non-volatile registers in some flashes. This means that if the flash was
set to 8D mode in a non-volatile configuration, a soft reset won't help.
This commit assumes that we don't set any non-volatile bits anywhere,

The spi-mem layer provides a spi_mem_supports_op() function to check
whether a specific operation is supported by the controller or not.
This is much more accurate than the hwcaps selection logic based on
SPI_{RX,TX}_ flags.
Rework the hwcaps selection logic to use spi_mem_supports_op().
To make sure the build doesn't break for boards not using CONFIG_DM_SPI,
add a simple SPI_{RX,TX}_ based hwcaps selection logic in spi-mem-nodm
similar to spi_mem_default_supports_op(). This change is only
compile-tested.
To avoid SPL size problems on the x530 board, the old hwcaps selection
is still kept around. Leaving the code in-place was getting difficult to
read and understand, so the code is restructured to have it all in one
isolated function. As a result of this, the parameter hwcaps to
spi_nor_setup() is no longer needed. Remove it.

Sometimes the information in a flash's SFDP tables is wrong. Sometimes
some information just can't be expressed in the SFDP table. So,
introduce the fixup hooks to allow tailoring settings for a specific
flash.
Three hooks are added: default_init, post_sfdp, and post_bfpt. These
allow tweaking the flash settings at different point in the probe
sequence. Since the hooks reside in nor->info, set that value just
before the call to spi_nor_init_params().
The hooks and at what points they are executed mimics Linux's spi-nor
framework. One major difference is that Linux puts the struct
spi_nor_fixups in nor->info. This is not possible in U-Boot because the
spi-nor-ids list is shared between spi-nor-core.c and spi-nor-tiny.c.
Since spi-nor-tiny shouldn't have those fixup hooks populated, add a
separate function that lets flashes populate their fixup hooks.

Set up opcode extension and enable/disable DTR mode based on whether the
command is DTR or not.
xSPI flashes can have a 4-byte dummy address associated with some
commands like the Read Status Register command in octal DTR mode. Since
the flash does not support sending the dummy address, we can not use
automatic write completion polling in DTR mode. Further, no write
completion polling makes it impossible to use DAC mode for DTR writes.
In that mode, the controller does not know beforehand how long a write
will be and so it can de-assert Chip Select (CS#) at any time. Once CS#
is de-assert, the flash will go into burning phase. But since the
controller does not do write completion polling, it does not know when
the flash is busy and might send in writes while the flash is not ready.
So, disable write completion polling and make writes go through indirect
mode for DTR writes and let spi-mem take care of polling the SR.

If the device tree provides a read delay value, use that directly and do
not perform the calibration procedure.
This allows the device tree to over-ride the read delay value in cases
where the read delay value obtained via calibration is incorrect. One
such example is the Cypress Semper flash. It needs a read delay of 4 in
octal DTR mode. But since the calibration procedure is run before the
flash is switched in octal DTR mode, it yields a read delay of 2. A
value of 4 works for both octal DTR and legacy modes.

spi_mem_default_supports_op() rejects DTR ops by default to ensure that
the controller drivers that haven't been updated with DTR support
continue to reject them. It also makes sure that controllers that don't
support DTR mode at all (which is most of them at the moment) also
reject them.
This means that controller drivers that want to support DTR mode can't
use spi_mem_default_supports_op(). Driver authors have to roll their own
supports_op() function and mimic the buswidth checks. Or even worse,
driver authors might skip it completely or get it wrong.
Add spi_mem_dtr_supports_op(). It provides a basic sanity check for DTR
ops and performs the buswidth requirement check. Move the logic for
checking buswidth in spi_mem_default_supports_op() to a separate
function so the logic is not repeated twice.

In xSPI mode, flashes expect 2-byte opcodes. The second byte is called
the "command extension". There can be 3 types of extensions in xSPI:
repeat, invert, and hex. When the extension type is "repeat", the same
opcode is sent twice. When it is "invert", the second byte is the
inverse of the opcode. When it is "hex" an additional opcode byte based
is sent with the command whose value can be anything.
So, make opcode a 16-bit value and add a 'nbytes', similar to how
multiple address widths are handled.
All usages of sizeof(op->cmd.opcode) also need to be changed to be
op->cmd.nbytes because that is the actual indicator of opcode size.

The get_mtd_device_nm() function (code imported from Linux) simply
iterates all registered MTD devices and compares the given name with
all MTDs' names.
With SPI_FLASH_MTD enabled U-Boot registers a SPI-NOR as a MTD device
with name identical to the SPI flash chip name (from SPI ID table). Thus
for a board with multiple same SPI-NORs it registers multiple MTDs, but
all with the same name (such as "s25fl164k"). We do not want to change
this behaviour, since such a change could break existing boot scripts,
which can rely on a hardcoded name.
In order to allow somehow to uniqely select a MTD device, change
get_mtd_device_nm() function as such:
- if first character of name is '/', try interpreting it as OF path
- otherwise compare the name with MTDs name and MTDs device name.
In the following example a board has two "s25fl164k" SPI-NORs. They both
have name "s25fl164k", thus cannot be uniquely selected via this name.
With this change, the user can select the second SPI-NOR either with
"spi-nor@1" or "/soc/spi@10600/spi-nor@1".
Example:
=> mtd list
List of MTD devices:
* s25fl164k
- device: spi-nor@0
- parent: spi@10600
- driver: jedec_spi_nor
- path: /soc/spi@10600/spi-nor@0
- type: NOR flash
- block size: 0x1000 bytes
- min I/O: 0x1 bytes
- 0x000000000000-0x000000800000 : "s25fl164k"
* s25fl164k

For NOR devices the logical DFU buffer size is the sector_size,
as it is done in dfu_sf.c or in spi/sf_mtd.c
(sf_mtd_info.erasesize = flash->sector_size)
For NAND the DFU size was already limited to erasesize as
has_pages = true.
So the mtd dfu backend can use this erasesize for all the MTD devices,
NOR and NAND with dfu->max_buf_size = mtd->erasesize
This difference was initially copied from MTD command, where
data is fully available in RAM without size limitation.
This patch avoids to have many sector write in dfu_mtd.c at the end
of the DFU transfer and avoids issues with USB timeout or WATCHDOG.

This feature set converts the boards pm9261 and pm9263 Ethernet support
to DM; enables hash command for all SAM boards; fixes the NAND pmecc
bit-flips correction; adds Falcon boot for sama5d3_xplained board; and
other minor adjustments.
Current tsec adapter sets adapter gigabit capabilities by default, and in
reality this must not always be the case.
It is possible that tsec adapter is used for 100Mbps connection, and in
this case setting 1000Mbps capabilities can lead to some side effects such
longer autoneg process.
In our ls102x designs this problem leads to long autoneg times (> 4 sec)
in case board rgmii link is 100Mbps capable only.
Limiting the rgmii link capabilities provides faster and smoother

This adds support for setting clock rates, which was left out of the
initial CCF expunging. There are several tricky bits here, mostly related
to the PLLS:
* The PLL's bypass is broken. If the PLL is reconfigured, any child clocks
will be stopped.
* PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent
stopping the CPU while we configure PLL0's rate, ACLK is reparented
to IN0 while PLL0 is disabled.
* PLL1 is the parent of the AISRAM clock. This clock cannot be reparented,
so we instead just disallow changing PLL1's rate after relocation (when
we are using the AISRAM).

This is effectively a complete rewrite to remove all dependency on CCF.
The code is now smaller, and so is the binary. It also takes up less memory
at runtime (since we don't have to create 40 udevices). In general, I am
much happier with this driver as much of the complexity and late binding
has been removed.
The k210_*_params structs which were previously used to initialize CCF
clocks are now used as the complete configuration. Since we can write our
own division logic, we can now do away with several "half" clocks which
only existed to provide constant factors of two.
The clock IDs have been renumbered to remove unused clocks. This may not be
the last time they are renumbered, since we have diverged with Linux. There
are also still a few clocks left out which may need to be added back in.
In general, I have tried to leave out behavioral changes. However, there is
a small bugfix regarding ACLK. According to the technical reference manual,
its mux comes *after* its divider (which is present only for PLL0). This
would have required yet another intermediate clock to fix with CCF, but
with the new driver it is just 2 lines of code :)

Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc
state for SPL only") it has been impossible to set clock defaults before
relocation. This is annoying on boards without SPL, since there is no way
to set clock defaults before U-Boot proper. In particular, the aisram rate
must be changed before relocation on the K210, since U-Boot will hang if we
try and change the rate while we are using aisram.
To get around this, extend the stage parameter to allow force setting
defaults, even if they would be otherwise postponed for later. A device
tree property was decided against because of the concerns in the original
commit thread about the overhead of repeatedly parsing the device tree.

commit, since the macros in sh-pfc.h also got updated, so
all the PFC tables must be updated in lockstep.

Not correcting anything in case of empty ECC data area
is not an appropriate strategy, because an uncorrected bit-flip
in an empty sector may cause upper layers (namely UBI) fail to work
properly. Therefore the approach chosen in Linux kernel and other
u-boot mtd drivers has been adopted, where a heuristic implemented
by nand_check_erased_ecc_chunk() is used in order to detect and
correct empty sectors.
Tested with sama5d3_xplained and sam9x60-ek.

'dma-ranges' frequently exists without parent nodes having 'dma-ranges'.
While this is an error for 'ranges', this is fine because DMA capable
devices always have a translatable DMA address. Also, with no
'dma-ranges' at all, the assumption is that DMA addresses are 1:1 with
no restrictions unless perhaps the device itself has implicit
restrictions.

The `ranges` DT property of the PCIe node is currently ignored by
Aardvark driver - all entries are used as transparent PCIe MEM, despite
some of them being defined for IO in DT.
This is because the driver does not setup PCIe outbound windows and thus
a default configuration is used.
This can cause an external abort on CPU when a device driver tries to
access non-MEM space.
Setup the PCIe windows according to the `ranges` property for all
non-MEM resources (currently only IO) and also non-transparent MEM
resources.
Because Linux expects that bootloader does not setup Aardvark PCIe
windows, disable them before booting Linux.

Disable Root Bridge I/O space, memory space and bus mastering in Aardvark's

cannot do new DMA transfers until Linux initializes PCI subsystem and loads
appropriate drivers for the device.
During initialization of PCI subsystem Linux in fact disables this bus

During our debugging of the Aardvark driver in Linux we have discovered
that the PCIE_CORE_LINK_CTRL_STAT_REG register in fact controls standard
PCIe Link Control Register for PCIe Root Bridge. This led us to discover
that the name of the PCIE_CORE_LINK_TRAINING macro and the corresponding
comment by this macro's usage is misleading; this bit in fact controls
Retrain Link, which, according to PCIe base spec is defined as:
A write of 1b to this bit initiates Link retraining by directing the
Physical Layer LTSSM to the Recovery state. If the LTSSM is already in
Recovery or Configuration, re-entering Recovery is permitted but not
required.
Entering Recovery state is normally done from LTSSM L0, L0s and L1 states.
But since the pci-aardvark.c driver enables Link Training just a few lines
above, the controller is not in L0 ready state yet. So setting aardvark bit
PCIE_CORE_LINK_TRAINING does not actually enter Recovery state at this
place.
Moreover, trying to enter LTSSM Recovery state without other configuration
is causing issues for some cards (e.g. Atheros AR9xxx and QCA9xxx). Since
Recovery state is not entered, these issues are not triggered.
Remove code which tries to enter LTSSM Recovery state completely.

There is a serious bug in regmap_read() and regmap_write() functions
where an uint pointer is cast to (void *) which is then cast to (u8 *),
(u16 *), (u32 *) or (u64 *), depending on register width of the map.
For example given a regmap with 16-bit register width the code
int val = 0x12340000;
regmap_read(map, 0, &val);
only changes the lower 16 bits of val on little-endian machines.
The upper 16 bits will remain 0x1234.
Nobody noticed this probably because this bug can be triggered with
regmap_write() only on big-endian architectures (which are not used by
many people anymore), and on little endian this bug has consequences
only if register width is 8 or 16 bits and also the memory place to
which regmap_read() should store it's result has non-zero upper bits,
which it seems doesn't happen anywhere in U-Boot normally. CI managed to
trigger this bug in unit test of dm_test_devm_regmap_field when compiled
for sandbox_defconfig using LTO.

- If we want to use fixed-link for an interface,
PHY handle is not defined in the DTS, and no
MDIO is registered.
There is a third case, for some boards (with switch),
the MDIO is used for switch configuration, but the interface
itself uses fixed link. This patch allows this option by

MDIO bus is registers, but the PHY address is set to

At present there is only one Kconfig option CONFIG_SIFIVE_CLINT to
control the enabling of SiFive CLINT support in both SPL (M-mode)
and U-Boot proper (S-mode). So for a typical SPL config that the
SiFive CLINT driver is enabled in both SPL and U-Boot proper, that
means the S-mode U-Boot tries to access the memory-mapped CLINT
registers directly, instead of the normal 'rdtime' instruction.
This was not a problem before, as the hardware does not forbid the
access from S-mode. However this becomes an issue now with OpenSBI
commit 8b569803475e ("lib: utils/sys: Add CLINT memregion in the root domain")
that the SiFive CLINT register space is protected by PMP for M-mode
access only. U-Boot proper does not boot any more with the latest
OpenSBI, that access exceptions are fired forever from U-Boot when
trying to read the timer value via the SiFive CLINT driver in U-Boot.
To solve this, we need to split current SiFive CLINT support between
SPL and U-Boot proper, using 2 separate Kconfig options.

This patch changes the functioning of the detection of w1 devices.
The old way was a comparison between detected w1 and the ones described in
the device tree. Now it will just look for the driver matching the family
id of the w1 detected.
The patch is inspired from Maxime Ripard code.
