This series includes two patches to fix alignment problems with linker
lists. In certain circumstances these can cause the drivers list to be
non-contiguous, causing crashes, hangs, etc.
Link: https://lore.kernel.org/r/20260321134626.516665-1-sjg@chromium.org
The extern declaration in ll_entry_get() lacks the __aligned(4)
attribute present in ll_entry_declare(). When the compiler sees an
unaligned extern reference to a linker list entry in the same
compilation unit as its definition, it may increase the section
alignment beyond the expected struct size. This causes gaps in the
linker list array, which the alignment checker reports as failures.
For example, sandbox_dir is both defined and referenced via
DM_DRIVER_GET() in sandboxfs.c. The compiler applies 32-byte
alignment to its section instead of the 4-byte alignment from the
definition, creating an 8-byte gap before it in the driver list.
Add __aligned(4) to the extern declaration in ll_entry_get() to
match ll_entry_declare()

Change the alignment of end markers in ll_entry_end() and ll_end_decl()
from __aligned(4) and __aligned(CONFIG_LINKER_LIST_ALIGN) respectively
to __aligned(1).
The linker places zero-size end markers at aligned boundaries based on
what follows them. When the next list's start marker has a high alignment
requirement (e.g., 32 bytes), padding gets inserted before the end
marker. This causes the byte span (end - start) to not be an exact
multiple of the struct size.
The compiler optimises pointer subtraction (end - start) using
magic-number multiplication for division. This optimisation only produces
correct results when the byte span is an exact multiple of the struct
size. With padding, the result is garbage (e.g., -858993444 instead of
15).
By using __aligned(1), the end marker is placed immediately after the
last entry with no padding, ensuring (end - start) equals exactly
(n * sizeof) where n is the number of entries. This makes
ll_entry_count() and direct pointer arithmetic work correctly.

This is a series adding support for reading U-Boot env directly from
SCSI devices that do not have a partition table, similar to how we can
already do this for MMC devices.
The motivation behind this is that MediaTek's BSP is already using the
same disk images for both MMC and UFS devices, so we need to be able to
read the env from SCSI devices without requiring a partition UUID.
The series starts with cleaning up a few oddities we noticed in the
existing code. Then some refactoring so that the env code manages
calling scsi_scan() so that we don't have to duplicate that for the
new code path. Then finally, the last few patches add and document the
new functionality.

The BOOTENV_DEV_UFS macro is incomplete - it only initializes UFS
and scans SCSI devices but does not actually boot anything. This
causes the boot sequence to stop after scsi scan without loading
a kernel.
Update BOOTENV_DEV_UFS to set the devnum environment variable to
the UFS instance number, initialize the device using $devnum, and
delegate the boot process to the shared scsi_boot script. Remove
the explicit scsi scan, as it is already handled by scsi_boot.
This matches the pattern used by other boot device macros and
ensures that UFS devices can successfully boot using the distro
boot framework.

Add support for eMMC specification version 5.1B by defining
MMC_VERSION_5_1B and including it in the version array.
eMMC 5.1B (JESD84-B51B) is a minor revision of the 5.1 specification
that primarily addresses MDT (Manufacturing Date) adjustment for dates
beyond 2025. This aligns with the Linux kernel commit 9996707822f82
("mmc: core: Adjust MDT beyond 2025").
Since the manufacturing date field is not currently used in U-Boot,
this change has no functional impact beyond proper device recognition.

that report version 5.1B in their Extended CSD register.

This driver adds the base support of pinctrl over SCMI. The driver
does two main things. First, it allows you to configure the initial
pin states. Secondly, it's used a base to build a GPIO driver on
top of it.
To configure the states then add a pinmux config to the scmi_pinctrl
section:
scmi_pinctrl: protocol@19 {
reg = <0x19>;
pinmux1: pinmux_test {
pinmux = <0 1 0xFFFFFFFF 18 1
0 2 0xFFFFFFFF 18 1
0 3 0xFFFFFFFF 18 1>;
function = "f_gpio1";
groups = "grp_1", "grp_3";
};
};
Under linux the pinctrl subsystem will parse the function and group
properties and use that to handle muxing. However, under u-boot the
pin muxing is done using the "pinmux" property, which feeds raw SCMI
pinctrl PINCTRL_SETTINGS_CONFIGURE commands to the server. The
numbers are: selector, identifier, function_id, config_type, and
config_value. In the example above, it sets pins 1, 2, and 3 to 1.
The linux-kernel ignores this pinmux property.

Each arch does something slightly different before booting the OS. Some
archs even do different things depending on the CPU type.
It is quite hard to know what actually happens in the final milliseconds
before the OS boot.
This series attempts to start cleaning up U-Boot in this area.
The basic intent is to create a new bootm_final() function which can be
called by all archs. It provides some flags for a couple of necessary
variations but otherwise it is generic.
All architectures are converted over to use this new function.
board_quiesce_devices() is moved into bootm_final() so that all archs
benefit from it.
This series fixes a bug in device_remove() is fixed where removing a
parent with specialised flags (e.g. DM_REMOVE_ACTIVE_ALL) could leave
children activated, since they do not match the flags. This fixes is
needed to avoid bootm_final() causing test failures on sandbox.
Future work could take this a little further:
- Convert EFI loader to use the same function
- Improve comments for cleanup_before_linux() across architectures
- Support fake-run tracing on all archs

There are various functions which announce that booting is imminent and
do related preparation. Most of these are arch-specific.
In practice, most archs do a similar thing. It would be better to
have a common function, with perhaps some events for things that are
really arch- and board-specific.
Create a new bootm_final() function with the common pre-boot steps:
printing the "Starting kernel" message, recording bootstage data,
optionally writing bootstage to the FDT and printing a report, and
removing active devices.
Be careful to avoid using BIT() macros which are not available with host
tools.

DDR size with EEC overhead already deducted.
Implementation details:
- Query the DDR size via scmi_misc_ddrinfo()
- Replace direct REG_DDR_CS[0,1]_BNDS register reads with SCMI call
- Switch from PHYS_SDRAM[x]_SIZE macros to runtime detection
- For backward compatibility with older SM firmware, fall back to
