8a0d07807a usb: udc: Try to clarify an error message
At some point when trying to use USB gadgets, two situations may arise
and lead to a failure. Either the UDC (USB Device Controller) is not
available at all (not described or not probed) or the UDC is already in
use. For instance, as the USB Ethernet gadget remains bound to the UDC,
the use of any other USB gadget (fastboot, dfu, etc) *after* will always
fail with the "couldn't find an available UDC" error.

Let's give a more helpful message by making a difference between the two
cases. Let's also hint people who would get this error and grep it into
the sources a better explanation of what's wrong with their workflow.

b272c87925 usb: ci: Fix gadget reinit
The ChipIdea device controller wasn't properly cleaned up when disabled.
So enabling it again left it in a broken state. The problem occurred for
example when the host unbinds the driver and binds it again.

During the first setup, when the out request is queued, the endpoint is
primed (`epprime`). If the endpoint is then disabled, it stayed primed
with the initial buffer. So after the endpoint is re-enabled, the device
controller and device driver were out of sync: the new out request was
in the driver queue head, yet not submitted, but the "complete" function
was still called, since the endpoint was primed with the old buffer.

With the fastboot function this error led to the (rather confusing)
error message "buffer overflow".

Fixed by clearing the primed buffers with the `epflush` (`ENDPTFLUSH`)
register.

beeb91aa64 scsi: set dma direction to NONE for TEST UNIT READY

With WDC SDINDDH6-64G ufs device, that caused TEST UNIT READY to

45c4b276f0 virtio: rng: gracefully handle 0 byte returns
According to the virtio v1.x "entropy device" specification, a virtio-rng
device is supposed to always return at least one byte of entropy.
However the virtio v0.9 spec does not mention such a requirement.

The Arm Fixed Virtual Platform (FVP) implementation of virtio-rng always
returns 8 bytes less of entropy than requested. If 8 bytes or less are
requested, it will return 0 bytes.
This behaviour makes U-Boot's virtio_rng_read() implementation go into an
endless loop, hanging the system.

Work around this problem by always requesting 8 bytes more than needed,
but only if a previous call to virtqueue_get_buf() returned 0 bytes.

This should never trigger on a v1.x spec compliant implementation, but
fixes the hang on the Arm FVP.

We use panic() instead of BUILD_BUG_ON in spl_set_bl_len because we still

This series tests raw nand flash in sandbox and fixes various bugs discovered in

(numerous) variations present on only a few boards. The test is pretty minimal.
Future work could test the rest of the nand API as well as the MTD API.

Bloat (for v1) at [1] (for boards with SPL_NAND_SUPPORT enabled). Almost
everything grows by a few bytes due to nand_page_size. A few boards grow more,
mostly those using nand_spl_loaders.c. CI at [2].

We disable BBT scanning, since scan_bbt is only populated when not in SPL.
We use nand_spl_loaders.c as it seems to be common to at least a few boards
already. However, we do not use nand_spl_simple.c because it would require
us to implement cmd_ctrl.  The various nand load functions are adapted from
omap_gpmc. However, they have been modified for simplicity/correctness.

bc8e8a4bfa nand: Add sandbox driver
Add a sandbox NAND flash driver to facilitate testing. This driver supports
any number of devices, each using a single chip-select. The OOB data is
stored in-band, with the separation enforced through the API.

For now, create two devices to test with. The first is a very small device
with basic ECC. The second is an 8G device (chosen to be larger than 32
bits). It uses ONFI, with the values copied from the datasheet. It also
doesn't need too strong ECC, which speeds things up.

Although the nand subsystem determines the parameters of a chip based on
the ID, the driver itself requires devicetree properties for each
parameter. We do not derive parameters from the ID because parsing the ID
is non-trivial. We do not just use the parameters that the nand subsystem
has calculated since that is something we should be testing. An exception
is made for the ECC layout, since that is difficult to encode in the device
tree and is not a property of the device itself.

Despite using file I/O to access the backing data, we do not support using
external files. In my experience, these are unnecessary for testing since
tests can generally be written to write their expected data beforehand.
Additionally, we would need to store the "programmed" information somewhere
(complicating the format and the programming process) or try to detect
whether block are erased at runtime (degrading probe speeds).

Information about whether each page has been programmed is stored in an
in-memory buffer. To simplify the implementation, we only support a single
program per erase. While this is accurate for many larger flashes, some
smaller flashes (512 byte) support multiple programs and/or subpage
programs. Support for this could be added later as I believe some
filesystems expect this.

To test ECC, we support error-injection. Surprisingly, only ECC bytes in
the OOB area are protected, even though all bytes are equally susceptible
to error. Because of this, we take care to only corrupt ECC bytes.
Similarly, because ECC covers "steps" and not the whole page, we must take
care to corrupt data in the same way.

38ef64e6ce spl: nand: Set bl_len to page size
Since commit 34793598c8 ("mtd: nand: mxs_nand_spl: Remove the page aligned
access") there are no longer any users of nand_get_mtd. However, it is
still important to know what the page size is so we can allocate a
large-enough buffer. If the image size is not page-aligned, we will go off
the end of the buffer and clobber some memory.

Introduce a new function nand_page_size which returns the page size. For
most drivers it is easy to determine the page size. However, a few need to
be modified since they only keep the page size around temporarily.

It's possible that this patch could cause a regression on some platforms if
the offset is non-aligned and there is invalid address space immediately
before the load address. spl_load_legacy_img does not (except when
compressing) respect bl_len, so only boards with SPL_LOAD_FIT (8 boards) or
SPL_LOAD_IMX_CONTAINER (none in tree) would be affected.

70d2c9940e mmc: renesas-sdhi: Disable clock after tuning reset when possible
Currently the renesas_sdhi_reset_tuning() unconditionally leaves SDHI
clock enabled after the tuning reset. This is not always necessary.

After the driver performed tuning reset at the end of probe function,
or in the unlikely case that tuning failed during regular operation,
the SDHI clock can be disabled after the tuning reset. The following
set_ios call would reconfigure the clock as needed.

In case of regular set_ios call which requires a tuning reset, keep
the clock enabled or disabled according to the mmc->clk_disable state.

With this in place, the controllers which have not been accessed via
block subsystem after boot are left in quiescent state. However, if an
MMC device is used e.g. for environment storage, that controller would
be accessed during the environment load and left active, including its
clock which would still be generated. This is due to the design of the
MMC subsystem, which does not deinit a controller after it was started
once, the controller is only deinited in case of mmc rescan, or before
OS boot.

ffb02942fa sunxi: board: simplify early PMIC setup conditions
So far we have a convoluted #ifdef mesh that guards the early AXP PMIC
setup in board.c. That combination of &&, || and negations is very hard
to read, maintain and especially to extend.

Fortunately we have those same conditions already modelled in the
Kconfig file, so they are actually redundant. On top of that the real
reason we have those preprocessor guards in the first place is about the
symbols that are *conditionally* defined: without #ifdefs the build
would break because of them being undefined for many boards.

To simplify this, just change the guards to actually look at the symbols
needed, so CONFIG_AXP_xxx_VOLT instead of CONFIG_AXPyyy_POWER.
This drastically improves the readability of this code, and makes adding
PMIC support a pure Kconfig matter.

Doing this revealed one bug in Kconfig: there is no axp_set_dcdc4() for
the AXP818, even though CONFIG_AXP_DCDC4_VOLT includes that PMIC.
Since the AXP818 wasn't included when calling axp_set_dcdc4() in board.c,
this wasn't an issue, but becomes one now, so also remove the AXP818 from
the DCDC4 Kconfig symbol.

ee2ce29223 bootstd: Skip over bad device during bootflows scanning
During bootstd scanning for bootdevs, if bootdev_hunt_drv() encounters
a device not found error (e.g. ENOENT), let it return a successful status
so that bootstd will continue scanning the next devices, not stopping
prematurely.

Background:

During scanning for bootflows, it's possible for bootstd to encounter a
faulty device controller. Also when the same u-boot is used for another
variant of the same board, some device controller such as SATA might
not exist.

I've found this issue while converting the Marvell Sheevaplug board to
use bootstd. This board has 2 variants, the original Sheevaplug has MMC and
USB only, but the later variant comes with USB, MMC, and eSATA ports. We
have been using the same u-boot (starting with CONFIG_IDE and later with DM
CONFIG_SATA) for both variants. This worked well with the old
envs-scripting booting scheme.

change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be

To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f31 ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.

The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.

d44f3d21fe net: designware: add DMA offset awareness
Older DesignWare Ethernet MAC versions that this driver supports can
only work with 32-bit DMA source/destination addresses. Some platforms
have no physical RAM at the lowest 4GB address space. For these
platforms the driver must translate DMA addresses to/from physical
memory addresses.

Call translation routines so that properly configured platforms can use
the DesignWare Ethernet MAC. For platforms using device-tree this
usually means adding dma-ranges property to the bus the device node is
in.

a56e30e65f net: phy: TI DP83869 fix invalid clock delay configuration
Setting the clock delay from the device tree settings
rx-internal-delay-ps and tx-internal-delay-ps was broken:

 - The expected value in the device tree is suppose to be a
   delay in picoseconds, but the driver only allowed an array index.
 - Driver converted this array index to the actual delay in
   picoseconds and tried to apply this in the device register. This
   however is not a valid register value. The actual logic here was
   reversed, it converted an register representation of the delay to
   the device tree delay in picoseconds.

Only when the internal delays were NOT configured in the device tree
and they default value of 7 (=2000ps) was used, a valid value was
loaded in the register.

0755db477f clk: use private clk struct in CLK_CCF's enable/disable functions
In clk_enable()/clk_disable() functions, when CCF is activated,
we must pass a private clk struct to enable()/disable() ops functions.
Otherwise, the use of a container_of() construction within these ops
should be banned. Because passing a non-private clk struct to
container_of() results in an out of range error.

At the moment, clk-mux, clk-fixed-factor, clk-gate and possibly other
clocks use container_of() in their enable()/disable() functions.
Therefore, for these functions to work correclty, private clk struct
must be passed.

In commit 5c5992cb90 ("clk: Add debugging for return values"), a
temporary storage variable was added around the ops->get_rate() call
inside clk_get_rate(), so that the result could be passed through
log_ret.

This temporary variable was declared as an int, yet when we look in
struct clk_ops, we can see this needs to be a ulong:
ulong (*get_rate)(struct clk *clk);

This was resulting in a signed to unsigned casting error on our
builds, where a clock value of 0xABCDABCD was being incorrectly cast
to 0xFFFFFFFFABCDABCD.

As noted in commit 3a6383207b ("mmc: sdhci: add the quirk for broken

complete bit with R1b responses.

According to the SD Host Controller Simplified Specification v4.20,

> In the case of a command pairing with response-with-busy[, Transfer
> Complete] is set when busy is de-asserted. Refer to DAT Line Active
> and Command Inhibit (DAT) in the Present State register.

By polling the DAT Line Active bit in the present state register, we can
detect when we are no longer busy, without waiting for a long timeout.
This results in much faster reads/writes on buggy controllers.

Merge tag 'tpm-next-27102023' of https://source.denx.de/u-boot/custodians/u-boot-tpm

bootX measurements and measurement API moved to u-boot core:

Up to now, U-Boot could perform measurements and EventLog creation as
described by the TCG spec when booting via EFI.

The EFI code was residing in lib/efi_loader/efi_tcg2.c and contained
both EFI specific code + the API needed to access the TPM, extend PCRs
and create an EventLog. The non-EFI part proved modular enough and
moving it around to the TPM subsystem was straightforward.

With that in place we can have a common API for measuring binaries
regardless of the boot command, EFI or boot(m|i|z), and contructing an
EventLog.

I've tested all of the EFI cases -- booting with an empty EventLog and
booting with a previous stage loader providing one and found no
regressions.  Eddie tested the bootX part.

Eddie also fixed the sandbox TPM which couldn't be used for the EFI code
and it now supports all the required capabilities. This had a slight
sideeffect in our testing since the EFI subsystem initializes the TPM
early and 'tpm2 init' failed during some python tests. That code only
opens the device though, so we can replace it with 'tpm2 autostart'
which doesn't error out and still allows you to perfom the rest of the
tests but doesn't report an error if the device is already opened.

There's a few minor issues with this PR as well but since testing and
verifying the changes takes a considerable amount of time, I prefer
merging it now.

Heinrich has already sent a PR for -master containing "efi_loader: fix
EFI_ENTRY point on get_active_pcr_banks" and I am not sure if that will
cause any conflicts, but in any case they should be trivial to resolve.

Both the EFI and non-EFI code have a Kconfig for measuring the loaded
Device Tree.  The reason this is optional is that we can't reason
when/if devices add random info like kaslr-seed, mac addresses etc in
the DT. In that case measurements are random, board specific and
eventually useless.  The reason it was difficult to fix it prior to this
patchset is because the EFI subsystem and thus measurements was brought
up late and DT fixups might have already been applied. With this
patchset we can measure the DT really early in the future.

Heinrich also pointed out that the two Kconfigs for the DTB measurements
can be squashed in a single one and that the documentation only explains
the non-EFI case.  I agree on both but as I said this is a sane working
version, so let's pull this first it's aleady big enough and painful to
test.

1332bdc2df mmc: tmio: Disable 1/1024 clock divider on Renesas R-Car platforms
The R-Car Gen3 SD_CLK_CTRL register does not use BIT(16) to implement
divider 1/1024, instead BIT(16) is reserved bit and divider 1/1024 is
not supported. The divider 1/1024 is specific to Socionext variant of
the IP, as is indicated by Linux commit:

0196c8db8363 ("mmc: tmio: move tmio_mmc_set_clock() to platform hook")
"
Socionext (and Panasonic) uses bit 10 (CLKSEL) for 1/1.  Also, newer
versions of UniPhier SoC variants use bit 16 for 1/1024.
"

Do not set the TMIO_SD_CAP_DIV1024 on Renesas R-Car platforms even if
the IP VERSION register does exist, and indicates IP version is newer
or equal to version 1.0 . The IP version 1.0 or newer does not imply
presence of the 1/1024 divider.

Since the TMIO driver is used exactly by two supported platforms, that
is Renesas R-Car and Socionext UniPhier, it is OK to check whether the
TMIO_SD_CAP_RCAR capability is not set to identify the UniPhier platform
and add the capability only on that platform.

35dc728a3c serial: introduce CONFIG_CONSOLE_FLUSH_ON_NEWLINE
When debugging, one sometimes only gets partial output lines or
nothing at all from the last printf, because the uart has a largish
buffer, and the code after the printf() may cause the CPU to hang
before the uart IP has time to actually emit all the characters. That
can be very confusing, because one doesn't then know exactly where the
hang happens.

Introduce a config knob allowing one to wait for the uart fifo to
drain whenever a newline character is printed, roughly corresponding
to the effect of setvbuf(..., _IOLBF, ...) in ordinary C programs.

Since this uses IS_ENABLED() instead of cpp ifdef, we can remove the
ifdef around the _serial_flush() definition - if neither
CONSOLE_FLUSH_SUPPORT or CONSOLE_FLUSH_ON_NEWLINE are enabled, the
compiler elides _serial_flush(), but it won't warn about it being
unused.

a8f6dab0d4 Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
This is mostly about support for the Allwinner R528/T113s SoC, which is
reportedly the same die as the Allwinner D1, but with the two
Arm Cortex-A7 cores activated instead of the RISC-V one.
Using sunxi code outside of arch/arm proved to be difficult, so apart
from enabling this Arm SoC, the patches also prepare for more refactoring
to get the D1 nicely supported some day:
- We get rid of some Kconfig (hard-)coded GPIO pins, responsible for
  enabling regulators.
- The GPIO code is moved out of arch/arm, into drivers/gpio.
- Some definitions are moved out of header files under asm/arch.
- Some T113s/D1 specific definitions are guarded by a generic Kconfig
  symbol (CONFIG_SUNXI_GEN_NCAT2).
- The DRAM controller initialisation code is located under drivers/ram.
- The base SoC .dtsi files are shared (under arch/riscv, as in Linux).

Of course there are also the usual new SoC specific patches, like clock
and pinmux descriptions, alongside a rework of the pinctrl code, since
Allwinner changed the GPIO register layout, for the first time since
sunxi's inception.
On top of this the PSCI code sees some update, to provide SMP services
for R528/T113s boards. Many thanks to Sam for providing this code and
staying strong through the review cycles.
The final patch enables support for one popular board, I hope to see
more DTs and defconfigs contributed in the future!

Many thanks to all the various contributors, testers and reviewers,
that series was a real team effort!

95168d77d3 sunxi: add Allwinner R528/T113 SoC support
This adds the remaining code bits to teach U-Boot about Allwinner's
newest SoC generation. This was introduced with the RISC-V based
Allwinner D1 SoC, which actually shares a die with the ARM cores versions
called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM).

This adds the new Kconfig stanza, using the two newly introduced symbols
for the new SoC generation and pincontroller. It also adds the new symbols
to the relavent code places, to set all the hardcoded bits directly.

We need one DT override:
The ARM core version of the DT specifies the CPUX watchdog as
"reserved", which means it won't be recognised by U-Boot. Override this
in our generic sunxi-u-boot.dtsi, to let U-Boot pick up this watchdog,
so that the generic reset driver will work.

124289bd56 sunxi: add R528/T113-s3/D1(s) DRAM initialisation code
The Allwinner R528/T113-s/D1/D1s SoCs all share the same die, so use the
same DRAM initialisation code.
Make use of prior art here and lift some code from awboot[1], which
carried init code based on earlier decompilation efforts, but with a
GPL2 license tag.
This code has been heavily reworked and cleaned up, to match previous
DRAM routines for other SoCs, and also to be closer to U-Boot's coding
style and support routines.
The actual DRAM chip timing parameters are included in the main file,
since they cover all DRAM types, and are protected by a new Kconfig
CONFIG_SUNXI_DRAM_TYPE symbol, which allows the compiler to pick only
the relevant settings, at build time.

The relevant DRAM chips/board specific configuration parameters are
delivered via Kconfig, so this code here should work for all supported
SoCs and DRAM chips combinations.

8bddb9742b Kconfig: sunxi: prepare for using drivers/ram/sunxi
At the moment all Allwinner DRAM initialisation routines are stored in
arch/arm/mach-sunxi, even though those "drivers" are just a giant
collection of writel's, without any architectural dependency.

The R528/T113-s SoC (with ARM cores) and the D1/D1s Soc (with RISC-V
cores) share the same die, so should share the same DRAM init routines as
well.

To prepare for this, add a new sunxi directory inside drivers/ram, and
add some stub entries to prepare for the addition of the share DRAM code
for those SoCs.

The RISC-V D1(s) SoCs will probably use SPL_DM, so for that SoC this
would be the right directory anyway.

4a9e89a3e3 sunxi: introduce NCAT2 generation model
Allwinner seems to typically stick to a common MMIO memory map for
several SoCs, but from time to time does some breaking changes, which
also introduce new generations of some peripherals. The last time this
happened with the H6, which apart from re-organising the base addresses
also changed the clock controller significantly. We added a
CONFIG_SUN50I_GEN_H6 symbol back then to mark SoCs sharing those traits.

Now the Allwinner D1 changes the memory map again, and also extends the
pincontroller, among other peripherals.
To mark this generation of SoCs, add a CONFIG_SUNXI_GEN_NCAT2 symbol,
this name is reportedly used in the Allwinner BSP code, and prevents us
from inventing our own name.

Add this new symbol to some guards that were already checking for the H6
generation, since many features are shared between the two (like the
renovated clock controller).

This paves the way to introduce a first user of this generation.

Ideally this would all be handled by devicetree and DM drivers, but for
the DT-less SPL we still need the legacy interfaces.

Add a new Kconfig symbol to differenciate between the two generations of

The rest is already abstracted enough, so works out of the box.

207ed0a3dd pinctrl: sunxi: remove GPIO_EXTRA_HEADER
U-Boot's generic GPIO_EXTRA_HEADER is a convenience symbol to allow code
to more easily include platform specific GPIO headers. This should not
be needed in a DM world anymore, since the generic GPIO framework
handles that nicely.
For Allwinner boards we still need to deal with non-DM GPIO in the SPL,
but this should become the exception, not the rule.

Make this more obvious by removing the definition of GPIO_EXTRA_HEADER,
and just force every legacy user of platform specific GPIO to include
the new sunxi_gpio.h header explicitly. Everyone doing so should feel
ashamed and should find a way to avoid it from now on.

30097ee3d2 pinctrl: sunxi: remove struct sunxi_gpio
So far every Allwinner SoC used the same basic pincontroller/GPIO
register frame, and just differed by the number of implemented banks and
pins, plus some special functionality from time to time. However the D1
and successors use a slightly different pinctrl register layout.
Use that opportunity to drop "struct sunxi_gpio", that described that
MMIO frame in a C struct. That approach is somewhat frowned upon in the
Linux world and rarely used there, though still popular with U-Boot.

Switching from a C struct to a "base address plus offset" approach allows
to switch between the two models more dynamically, without reverting to
preprocessor macros and #ifdef's.

Model the pinctrl MMIO register frame in the usual "base address +
offset" way, and replace a hard-to-parse CPP macro with a more readable
static function.
All the users get converted over. There are no functional changes at
this point, it just prepares the stages for the D1 and friends.

5ad98c57b8 sunxi: remove CONFIG_MACPWR

In the DT this is described with the phy-supply property in the MAC DT

instead of hardcoding this.

Add code to the sun8i_emac and sunxi_emac drivers to check the DT for
that regulator and enable it, at probe time. Then drop the current code
from board.c, which was doing that job before.

091442993c net: sunxi_emac: chase DT nodes to find PHY regulator
At the moment the sun4i EMAC driver relies on hardcoded CONFIG_MACPWR
Kconfig symbols to enable potential PHY regulators. As we want to get rid
of those, we need to find the regulator by chasing up the DT.

The sun4i-emac binding puts the PHY regulator into the MDIO node, which
is the parent of the PHY device. U-Boot does not have (and does not
need) an MDIO driver, so we need to chase down the regulator through the
EMAC node: we follow the "phy-handle" property to find the PHY node,
then go up to its parent, where we find the "phy-supply" link to the
regulator. Let U-Boot find the associated regulator device, and put that
into the private device struct, so we can find and enable the regulator
at probe time, later.

The current SCIF error handling is broken for the RZ/G2L. After a break

The RZ/G2L datasheet says that most error conditions are cleared by
resetting the relevant error bits in the FSR & LSR registers to zero.
To clear framing errors on SCIF ports, the invalid data also needs to be
read out of the receive FIFO.

After reviewing datasheets for RZ/G2{H,M,N,E}, R-Car Gen4, R-Car Gen3
and even SH7751 SoCs, it's clear that this is the way to clear errors
for all of these SoCs.

eaf738559c spl: Allow enabling SPL_OF_REAL and SPL_OF_PLATDATA at the same time
Sandbox unit tests in U-Boot proper load a test device tree to have some
devices to work with. In order to do the same in SPL, we must enable
SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When
generating platdata from a devicetree, it is expected that we will not need
devicetree access functions (even though SPL_OF_CONTROL is enabled). This
expectation does not hold for sandbox, so allow user control of
SPL_OF_REAL.

There are several places in the tree where conditions involving OF_PLATDATA
or OF_REAL no longer function correctly when both of these options can be
selected at the same time. Adjust these conditions accordingly.

ab12179b3e arm: imx: Check header before calling spl_load_imx_container
Make sure we have an IMX header before calling spl_load_imx_container,
since if we don't it will fail with -ENOENT. This allows us to fall back to
legacy/raw images if they are also enabled.

This is a functional change, one which likely should have been in place
from the start, but a functional change nonetheless. Previously, all
non-IMX8 images (except FITs without FIT_FULL) would be optimized out if
the only image load method enabled supported IMX8 images. With this change,
support for other image types now has an effect.

There are seven boards with SPL_LOAD_IMX_CONTAINER enabled: three with
SPL_BOOTROM_SUPPORT:

    imx93_11x11_evk_ld imx93_11x11_evk imx8ulp_evk

and four with SPL_MMC:

    deneb imx8qxp_mek giedi imx8qm_mek

All of these boards also have SPL_RAW_IMAGE_SUPPORT and
SPL_LEGACY_IMAGE_FORMAT enabled as well. However, none have FIT support
enabled. Of the six load methods affected by this patch, only SPL_MMC and
SPL_BOOTROM_SUPPORT are enabled with SPL_LOAD_IMX_CONTAINER.
spl_romapi_load_image_seekable does not support legacy or raw images, so
there is no growth. However, mmc_load_image_raw_sector does support loading
legacy/raw images. Since these images could not have been booted before, I
have disabled support for legacy/raw images on these four boards. This
reduces bloat from around 800 bytes to around 200.

There are no in-tree boards with SPL_LOAD_IMX_CONTAINER and AHAB_BOOT both
enabled, so we do not need to worry about potentially falling back to
legacy images in a secure boot scenario.

Future work could include merging imx_container.h with imx8image.h, since
they appear to define mostly the same structures.

21e4ba153f gpio: Add RZ/G2L GPIO driver
This driver adds support for the gpio features of the GPIO/PFC module in
the Renesas RZ/G2L (R9A07G044) SoC.

The new `rzg2l-pfc-gpio` driver is bound to the same device tree node as
the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both
GPIO and pin multiplexing features.

This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

This driver adds support for the pinctrl features of the GPIO/PFC module

A multi-function `rzg2l-pfc` driver is defined for UCLASS_NOP, which
binds the `rzg2l-pfc-pinctrl` UCLASS_PINCTRL driver dynamically. We also
define common macros and functions for the PFC in <renesas/rzg2l-pfc.h>.
This makes it easy to add an additional UCLASS_GPIO driver for the GPIO
functionality of this module in a follow-up patch.

1918ff5c95 clk: renesas: Add RZ/G2L & RZ/G2LC CPG driver
This driver provides clock and reset control for the Renesas R9A07G044L
(RZ/G2L) and R9A07G044C (RZ/G2LC) SoC. It consists of two parts:

* driver code which is applicable to all SoCs in the RZ/G2L family.

* static data describing the clocks and resets which are specific to the
  R9A07G044{L,C} SoCs. The identifier r9a07g044 (without a final letter)
  is used to indicate that both SoCs are supported.

clk_set_rate() and clk_get_rate() are implemented only for the clocks
that are actually used in u-boot.

The CPG driver is marked with DM_FLAG_PRE_RELOC to ensure that its bind
function is called before the SCIF (serial port) driver is probed. This
is required so that we can de-assert the relevant reset signal during
the serial driver probe function.

This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

To fix this, only try to support access to the HSSRR register for SoCs

ec8727b7e1 firmware: scmi: implement SCMI base protocol
SCMI base protocol is mandatory according to the SCMI specification.

With this patch, SCMI base protocol can be accessed via SCMI transport
layers. All the commands, except SCMI_BASE_NOTIFY_ERRORS, are supported.
This is because U-Boot doesn't support interrupts and the current transport
layers are not able to handle asynchronous messages properly.

689204be97 firmware: scmi: use a protocol's own channel if assigned
SCMI specification allows any protocol to have its own channel for
the transport. While the current SCMI driver may assign its channel
from a device tree, the core function, devm_scmi_process_msg(), doesn't
use a protocol's channel, but always use an agent's channel.

With this commit, devm_scmi_process_msg() tries to find and use
a protocol's channel. If it doesn't exist, use an agent's.

5fecea171d treewide: use dev_read_addr_*_ptr() where appropriate
A follow-up to commit 842fb5de42
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer")
and commit 320a1938b6
("drivers: use devfdt_get_addr_index_ptr when cast to pointer").

In addition to using the *_ptr variants of these functions where the
address is cast to a pointer, this also changes devfdt_get_addr_*() to
dev_read_addr_*() in a few places. Some variable and field types are
changed from fdt_addr_t or phys_addr_t to void* where the cast was
happening later.

This patch fixes a number of compile warnings when building a 32bit
U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error
handling where the return value of dev_read_addr() etc. was checked for
NULL instead of FDT_ADDR_T_NONE.

bc8e94c902 usb: gadget: atmel: fix transfer of queued requests
In the existing implementation, multiple requests queued up on an
endpoint are subject to getting evicted without transmission.

For both control and bulk endpoints, their respective logic found in
usba_control_irq()/usba_ep_irq() guarantees that TX FIFO is empty before
data is sent out, and that request_complete() gets called once the
transaction has been finished. At this point however, if any additional
requests are found on the endpoint queue, they will be processed by
submit_next_request(), which makes no checks against the above
conditions, trashing data on a busy FIFO and neglecting completion
handlers.

Fix the above issues by removing the calls to submit_next_request(),
and thus forcing the pending requests to be processed on the next pass
of the respective endpoint logic. While at it, remove a DBG message, as
that branch becomes part of regular flow.

This restores mass storage mode operation on Microchip ATSAMA5D27 SoC.

be0da1257f dfu: mtd: mark bad the MTD block on erase error
In the MTD DFU backend, it is needed to mark the NAND block bad when the
erase failed with the -EIO error, as it is done in UBI and JFFS2 code.

This operation is not done in the MTD framework, but the bad block
tag (in BBM or in BBT) is required to avoid to write data on this block
in the next DFU_OP_WRITE loop in mtd_block_op(): the code skip the bad
blocks, tested by mtd_block_isbad().

Without this patch, when the NAND block become bad on DFU write operation
- low probability on new NAND - the DFU write operation will always failed
because the failing block is never marked bad.

This patch also adds a test to avoid to request an erase operation on a
block already marked bad; this test is not performed in MTD framework
in mtd_erase().

b20913e3cb mtd/spinand: rework detect procedure for different READ_ID operation
Currently there are 3 different variants of read_id implementation:
1. opcode only. Found in GD5FxGQ4xF.
2. opcode + 1 addr byte. Found in GD5GxGQ4xA/E
3. opcode + 1 dummy byte. Found in other currently supported chips.

Original implementation was for variant 1 and let detect function
of chips with variant 2 and 3 to ignore the first byte. This isn't
robust:

1. For chips of variant 2, if SPI master doesn't keep MOSI low
during read, chip will get a random id offset, and the entire id
buffer will shift by that offset, causing detect failure.

2. For chips of variant 1, if it happens to get a devid that equals
to manufacture id of variant 2 or 3 chips, it'll get incorrectly
detected.

This patch reworks detect procedure to address problems above. New
logic do detection for all variants separatedly, in 1-2-3 order.
Since all current detect methods do exactly the same id matching
procedure, unify them into core.c and remove detect method from
manufacture_ops.
