bootstd: Fix incorrect struct name in bootmeth_setup_iter_order()
There is no such thing as struct bootmeth, it's probably a typo. This
issue doesn't affect the execution as it's a pointer, and pointer sizes
are the same for all data types. But it can be confusing, so make it
struct udevice, as it should be.

bootstd: Probe bootmeth devices for bootmeths env var
Specifying efi_mgr in 'bootmeths' environment variable leads to NULL
pointer dereference when 'bootflow scan' is executed, with call trace
like this:
priv->fake_dev // NULL pointer dereference
.read_bootflow = efi_mgr_read_bootflow()
bootmeth_get_bootflow()
bootflow_check()
bootflow_scan_first()
do_bootflow_scan()
'bootflow scan -l'
That happens because in case when 'bootmeths' env var is defined the
bootmeth_efi_mgr driver is not probed, and the memory for its private
data isn't allocated by .priv_auto. In case when 'bootmeths' env var is
not defined, the std->bootmeth_count is 0, and the execution flow in
bootmeth_setup_iter_order() takes "no ordering" path, which in turn runs
uclass_get_device_by_seq() -> ... -> device_probe(), so issue isn't
present there. But when 'bootmeths' is defined and contains efi_mgr, the
std->bootmeth_count > 0, so bootmeth_setup_iter_order() follows the "we
have an ordering" path, where devices are not probed. In other words:
'bootmeths' defined 'bootmeths' not defined
--------------------------------------------------------
priv == NULL priv != NULL
^ ^
| device_alloc_priv()
no probe device_of_to_plat()
^ device_probe()
| uclass_get_device_tail()
dev = order[i] uclass_get_device_by_seq()
^ ^
| have an ordering | no ordering
+----------------+---------------+
|
bootmeth_setup_iter_order()
bootflow_scan_first()
do_bootflow_scan()
Add an explicit device_probe() call in "we have an ordering" case to fix
the issue.

Merge patch series "bootstd: New bootmeth for RAUC A/B systems"
Martin Schwan <m.schwan@phytec.de> says:
This series implements a new bootmeth for RAUC A/B systems. RAUC (Robust
Auto Update Controller) is a lightweight update client, providing "Safe
and Secure OTA Updates for Embedded Linux". See the following links for
more information about RAUC:
https://rauc.io/
https://rauc.readthedocs.io/en/latest/
PHYTEC uses RAUC in its Yocto based distribution "Ampliphy" as the
default way of updating embedded devices based on PHYTEC hardware. So
far, the logic selecting the correct partitions and files to boot was
being implemented in the U-Boot environment. While this is a
straightforward way to do it, adding and supporting new platforms became
somewhat tedious and is platform-specific. The introduction of U-Boot's
"Standard Boot" provided a convincing alternative, promising a simpler
and more portable way of booting, even for RAUC systems. This led me to
implement a new bootmeth supporting RAUC A/B systems. Note, that this
new bootmeth is not proprietary to PHYTEC products and is designed to
work on other hardware with a RAUC A/B system, too.
The bootmeth currently only supports symmetric A/B partitioning layouts.
E.g. A/rescue is not (yet) supported. The partition indexes and default
slot tries can be specified via configuration options.
For now, the bootmeth_rauc uses a similar approach for loading the
Kernel and device tree as the bootmeth_script, in that it requires a FIT
containing a U-Boot script loading the desired distro. It could be
possible to support booting without a script and load the Kernel and DT
directly with this bootmeth, but I found the script method to be very
flexible for now, in letting the distro decide what to load.
The bootmeth_rauc was tested on a phyBOARD-Pollux i.MX8M Plus [1] with
BSP-Yocto-Ampliphy-i.MX8MP-PD24.1.2 [2].
Supported boot devices are currently only MMC devices, but it should be
possible to add SPI flashes in the future.
To test this patch stack with PHYTEC's phyBOARD-Pollux i.MX8M Plus
board, you need to adjust the boot files to include the boot.scr.uimg
containing the distro's boot script and set "optargs" to "${raucargs}"
in it. Also disable any legacyboot in the U-Boot environment and simply
boot with Standard Boot:
bootmeth order rauc
bootflow scan -lb

linux/list.h: drop use of prefetch()
The use of prefetch() in these list helpers was dropped back in 2011
in linux (
e66eed651fd1 ("list: remove prefetching from regular list
iterators")). No arch in U-Boot defines any actual prefetch(), and as
the referenced commit says, it's usually not a win anyway.
Whole-sale sync of list.h is not really feasible, but we can
synchronize the macros containing a prefetch() with their linux
implementations as of v6.15-rc5, also importing the various helpers
needed, e.g. list_is_head() and list_next_entry().

usb: gadget: atmel: reliably generate disconnect by disabling controller
Contrary to the datasheet, setting both DETACH and PULLD_DIS bits to 1
does not always drive the DP and DM lines to high-impedance. This
prevents the host from reliably detecting a USB disconnect and subsequent
reconnect.
The symptom is that the first gadget command (e.g., dhcp) succeeds, while
subsequent commands (e.g., nfs) fail.
Disabling and re-enabling the controller entirely, instead of toggling the
PULLD_DIS bit, reliably generates a disconnect event.
The Linux driver works correctly because gadget_disconnect/gadget_connect
are always followed by gadget_udc_start/gadget_udc_stop. In U-Boot
pullup() is used solely.
This behavior has been observed on the SAM9X60-Curiosity and
AT91SAM9G25-EK boards and has been reported to Microchip.

2. Pins LCD_DATA0 - LCD_DATA15, gpmc_ad8 - gpmc_ad15 and

pwm: ti: am33xx: Enable Auxiliary PWM using eCAP
In am33xx SoC[1], enhanced capture (eCAP) supports auxiliary PWM (APWM).
This series adds the PWM driver support for the APWM feature for eCAP on
AM33xx.
eCAP HW also supports the capture mode. Currently, this driver only
supports APWM.
This is based on the Linux kernel driver -> drivers/pwm/pwm-tiecap.c
Version: v6.12

ram: Move Kconfig options into their own menu entry
RAM drivers using Device Model currently lack of their own Kconfig menu
entry, which makes Kconfig put all options of the class in the top-level

pinctrl options in the generated .config, which is hard to read. Let's

fdt: Make sure there is no stale initrd left
Although if we don't setup an initrd, there could be a stale initrd
setting from the previous boot firmware in the live device tree. So,
make sure there is no setting left if we don't want an initrd.
This can happen when booting on a Raspberry Pi. The boot firmware can
happily load an initrd before us and configuring the addresses in the
live device tree we get handed over.
Especially the setting `auto_initramfs` in config.txt is dangerous.
When enabled (default), the firmware tries to be smart and looks for
initramfs files.

ext4fs: Fix: Read outside partition error (take 2)
Use lbaint_t for blknr to avoid overflow in ext4fs_read_file().
Background:
blknr (block number) used in ext4fs_read_file() could be increased to a
very large value and causes a wrap around at 32 bit signed integer max,
thus becomes negative. This results in an out-of-normal range for sector
number (during the assignment delayed_start = blknr) where delayed_start
sector is typed uint64 lbaint_t. This causes the "Read outside partition"
error.
Looks like we also have this overflown problem in ext4_write.c that needs
to be addressed.
This patch was tested on the Synology DS116 (Armada 385) board, and a
4TB Seagate HDD.
