Use alias-based RAM probing to detect different memory configurations
on Toradex Aquila iMX95. The address wrap-around is not linear: address
bits above the module capacity alias back with some low address bits
XORed (bit 32 -> XOR 0xc000), as measured on 4GB and 8GB modules.
During probing, skip the first 256MB, since that region is reserved.

Although it has similar naming the Librem 5 Devkit is a completely
different design from the Librem 5 phone. It uses an imx8mq SOM from
Emcraft, a separate HDMI port instead of DisplayPort, different USB-C
chip, panel, etc.
This is based on a Emcraft's SOM documentation, Purism's downstream fork
and the available schematics of the devkit.

With CONFIG_FIT_BEST_MATCH, fit_conf_find_compat() selects the
configuration matching the most specific U-Boot compatible string; on
equal matches the first listed configuration wins and the configurations
node 'default' property is never consulted.
A FIT whose configurations all share the same base devicetree compatible
(e.g. one manifest carrying a base tree plus overlay combinations for a
single board) therefore always boots the first configuration, silently
ignoring the default chosen by the manifest author.
Break score ties in favour of the default configuration. A strictly
better compatible match still wins over it, and FITs without a default
keep the current first-listed behaviour.

Rasmus Villemoes <[email protected]> says:
This started by me wanting something like what patch 8 does. That
wasn't too hard, except we had no strcasestr(), and also our regex
engine (which I didn't really want to pull into the mix anyway)
doesn't have a flag that requests case-insensitive matching. So I
wanted to add strcasestr(), but then I stumbled on a bunch of stuff
that should be cleaned up in str-land.

While this is not likely needed by any "real" driver code, a later
convenience addition to the "config" command will need this. As usual,
the linker will throw it away if nothing actually uses it, so it

None of these six macros are defined by any architecture. Moreover,
the ifndef guard only exists in either string.h or string.c, making them
completely pointless.
I'm not sure whether we have an explicit coding style discouraging the
"extern" qualifier on function declarations, and string.h has a random
mix of everything, but I can't leave it on strncasecmp() now that it
will be immediately after strcasecmp() which doesn't have it.

similar ever appear, it is better done with some proper

The existing K1 reset driver (drivers/reset/reset-spacemit-k1.c) binds
via DT of_match against a top-level reset-controller node, but kernel
mainline DT for K1 has no such node: the mpmu, apbc, apmu and apbc2
syscons each spawn their own reset device as an auxiliary of the
clock controller. The legacy driver therefore cannot consume it.
Add a new reset driver at drivers/reset/spacemit/reset-spacemit-k1.c
bound by name from each per-syscon clock driver via
device_bind_driver_to_node(), without DT of_match, mirroring the
kernel's auxiliary-device pattern.
To keep the series bisectable, this driver coexists link-cleanly with
the legacy spacemit,k1-reset driver during the transition. A
follow-up patch that switches the K1 build to
dts/upstream/src/riscv/spacemit/ will drop the legacy driver.

The K1 SoC exposes four clock providers in the kernel mainline DT: one
PLL controller ("spacemit,k1-pll") and three syscon clock nodes
("spacemit,k1-syscon-{mpmu,apbc,apmu}"). Register a separate
U_BOOT_DRIVER for each.
The controllers register clocks into a single CCF namespace, and a clock
in one controller may parent off a clock owned by another, so a
controller must register only after the controllers that own its parents
have probed. Each probe forces its parent controllers up by driver:
MPMU <- PLL
APMU <- PLL, MPMU
APBC <- PLL, MPMU, APMU

The DesignWare SPI controller supports configurable bits_per_word
(typically 4-32 bits), but this was previously hardcoded to 8 bits
in the driver initialization.
This patch enables bits_per_word to be set dynamically by upper-level
device drivers, matching the approach used in Linux. The controller
reads the bits_per_word value from the spi_slave structure during
each transfer, allowing different SPI devices on the same bus to use
different word sizes.
Implementation details:
- Read slave->bits_per_word in dw_spi_xfer() before each transfer
- Validate requested value against controller capabilities (4 to max_xfer)
- Default to 8 bits if not set (maintains backward compatibility)
This follows the Linux model where spi_device drivers set bits_per_word,
and the controller driver reads it in the transfer function. Device
drivers can now set slave->bits_per_word before calling spi_xfer().
Example usage in device driver:
slave->bits_per_word = 16;
spi_xfer(slave, ...);
Backward compatible: Existing drivers that don't set bits_per_word
will continue to work with the default 8-bit transfers.

The fdt checksign command accepts an optional address for an FDT
containing public keys. It currently installs that blob as gd->fdt_blob
before verifying the FIT configuration.
This breaks verification with DM-backed crypto drivers which have not
probed yet, since the later probe path expects gd->fdt_blob to remain
U-Boot's control FDT. For example, an ECDSA verifier can be bound from
the control FDT but fail to probe after fdt checksign points
gd->fdt_blob at the key-only DTB.
Add a FIT config verification helper that takes the key blob explicitly
and use it from fdt checksign. This keeps gd->fdt_blob unchanged while
still allowing the command to verify against an external key DTB.

PMBus regulators differ in numeric formats and quirks, not in how they
are driven. Share that common behaviour as a regulator-uclass adapter
so chip drivers and the pmbus CLI do not each reimplement the decode

compliant chips that have no dedicated driver yet.

Add U-Boot's PMBus 1.x layer: the decoder/transport library, the
pmbus CLI command and a generic DT binding.
The subsequent commits provide the UCLASS_REGULATOR adapter and per-chip
drivers.
U-Boot's PMBus support is not a hwmon clone of Linux's
drivers/hwmon/pmbus/. Linux owns the runtime side (polling, sysfs,
alert IRQs, fan loops). U-Boot owns the boot-time side in order to,
- identify the PMBus regulators a board carries: MFR_ID/
MFR_MODEL/MFR_REVISION + sanity checks.
- print telemetry (VIN/VOUT/IIN/IOUT/POUT/TEMP) so an
operator can confirm rail voltages and faults before the kernel
- decode any chip alerts (STATUS_VOUT/STATUS_IOUT/STATUS_INPUT/
STATUS_TEMPERATURE/STATUS_CML) so a boot log shows why the
previous boot failed or the board had been power cycled because
of an outage (typically over temperature or under current).
Out of scope by design: no periodic polling, no sysfs, no fan-speed
control loop, no PMBUS_VIRT_* sensor virtualisation, no caching.
If a use case needs any of those, the answer should be "wait until
Linux comes up". It shall remain a thin layer.
The constants and structural shape (command codes, status bit names,
sensor-class enum, format enum, struct pmbus_driver_info) are
mirrored from Linux drivers/hwmon/pmbus/pmbus.h verbatim. The
decoders/encoders are reimplemented from the PMBus 1.3
specification because the surrounding hwmon context (struct
pmbus_data, sysfs caching, hwmon publication) does not apply.
The main benefits:
- One framework + CLI for any board carrying PMBus regulators:
no per-board PMBus implementation required anymore.
- Boards call pmbus_print_telemetry() / pmbus_print_status_word()
directly from boot init for a snapshot, sharing all decode +
format-dispatch with the CLI.
- Linux-compatible constants and DT binding so porting an existing
drivers/hwmon/pmbus/ chip is mechanical.
- Boot-time AVS/VID rail trim reuses the same decoders and
encoders as the CLI and the regulator path: no duplicate math.

The commit 076265b75e61 ("compat: regulator: add enable/disable macros")
added regulator_enable/disable() macros to provide a closer analogue to
the Linux API.
These new macros wrap regulator_set_enable() that may return detailed
error codes and should typically not directly be called by drivers.
Change the macros to wrap regulator_set_enable_if_allowed() that masks
error codes consumers typically do not expect to closer match the
behavior of the Linux API.
Also move the macros outside the #if #else blocks to make the macros
available when !CONFIG_IS_ENABLED(DM_REGULATOR).

This patch series add pin controller and gpio driver support for EN7523/
AN7581/AN7583 SoCs. The driver based on official linux airoha pinctrl

The original Matheus Sampaio Queiroga driver can be taken from the repo:

Additionally in the EN7523 case the patches removes existing gpio dts
nodes and replaces them with pinctrl node. It should not be very
dangerous, because:
* No official EN7523 gpio support present in U-Boot
* Legacy Linux EN7523 GPIO driver is mostly abandoned
* The same driver is planned for upstream linux/openwrt
This patchset includes bitfield.h patches created for Linux kernel by
Geert Uytterhoeven. It suits U-Boot fine. I preserve original author and

The existing FIELD_{GET,PREP}() macros are limited to compile-time
constants. However, it is very common to prepare or extract bitfield
elements where the bitfield mask is not a compile-time constant.
To avoid this limitation, the AT91 clock driver and several other
drivers already have their own non-const field_{prep,get}() macros.
Make them available for general use by adding them to
<linux/bitfield.h>, and improve them slightly:
1. Avoid evaluating macro parameters more than once,
2. Replace "ffs() - 1" by "__ffs()",
3. Support 64-bit use on 32-bit architectures,
4. Wire field_{get,prep}() to FIELD_{GET,PREP}() when mask is
actually constant.
This is deliberately not merged into the existing FIELD_{GET,PREP}()
macros, as people expressed the desire to keep stricter variants for
increased safety, or for performance critical paths.
Yury: use __mask within new macros.

The BUILD_BUG_ON_MSG() check against "~0ull" works only with "unsigned
(long) long" _mask types. For constant masks, that condition is usually
met, as GENMASK() yields an UL value. The few places where the
constant mask is stored in an intermediate variable were fixed by
changing the variable type to u64.
However, for non-constant masks, smaller unsigned types should be valid,
too, but currently lead to "result of comparison of constant
18446744073709551615 with expression of type ... is always
false"-warnings with clang and W=1.
Hence refactor the __BF_FIELD_CHECK() helper, and factor out
__FIELD_{GET,PREP}(). The later lack the single problematic check, but
are otherwise identical to FIELD_{GET,PREP}(), and are intended to be
used in the fully non-const variants later.

Export the following functions to public:
- ubi_detach(): this is paired with ubi_part(). One may call this function
to completely clean up the ubi subsystem after using ubi_part().
- ubi_{create,find,remove}_vol: this is a set of functions for volume
management.
The original ubi_remove_vol is renamed to __ubi_remove_vol to allow the new
ubi_remove_vol() being used as a wrapper for __ubi_remove_vol() with volume
name.
Also, comments are added for all exported functions.

File name and volume name should be const as they will not be modified in
these functions.

Use void * to avoid explicit type casting as what ubi_volume_write has done
already.

Parameters like part/volume name and buffer for writing are not being
