008c4b3c31 cyclic: make clients embed a struct cyclic_info in their own data structure
There are of course not a whole lot of examples in-tree yet, but
before they appear, let's make this API change: Instead of separately
allocating a 'struct cyclic_info', make the users embed such an
instance in their own structure, and make the convention that the
callback simply receives the 'struct cyclic_info *', from which the
clients can get their own data using the container_of() macro.

This has a number of advantages.

First, it means cyclic_register() simply cannot fail, simplifying the
code. The necessary storage will simply be allocated automatically
when the client's own structure is allocated (often via
uclass_priv_auto or similar).

Second, code for which CONFIG_CYCLIC is just an option can more easily
be written without #ifdefs, if we just provide an empty struct
cyclic_info {}. For example, the nested CONFIG_IS_ENABLED()s in
https://lore.kernel.org/u-boot/20240316201416.211480-1-marek.vasut+renesas@mailbox.org/
are mostly due to the existence of the 'struct cyclic_info *' member
being guarded by #ifdef CONFIG_CYCLIC.

And we do probably want to avoid the extra memory overhead of that
member when !CONFIG_CYCLIC. But that is automatic if, instead of a
'struct cyclic_info *', one simply embeds a 'struct cyclic_info',
which will have size 0 when !CONFIG_CYCLIC. Also, the no-op
cyclic_register() function can just unconditionally be called, and the
compiler will see that (1) the callback is referenced, so not emit a
warning for a maybe-unused function and (2) see that it can actually
never be reached, so not emit any code for it.

3a11eada38 cyclic: stop strdup'ing name in cyclic_register()
We are not checking the return value of strdup(), nor
freeing the string in cyclic_unregister().

However, all current users either pass a string literal or the
dev->name of the client device. So in all cases the name string will
live at least as long as the cyclic_info is registered, so just make
that a requirement.

This series contains improvements for the 'eeprom' command:
- refactors
- fixes
- improvements
- ability to use driver model EEPROMs (uclass UCLASS_I2C_EEPROM)
- more flexible EEPROM layout support

It should not cause any behavior change for any existing board.

977fc15e98 Merge patch series "mcheck implementation for U-Boot"
Eugene Uriev <eugeneuriev@gmail.com> says:

There was no "mcheck" for U-Boot before.

Since U-Boot has only 1 thread, and normally makes 4000+ - 6000+
mallocs, it's better to use havier canaries to protect heap-chunks.
My variant uses 2x8 = 16byte-long protector. And
the multiplier could be changed to tune speed/protection tradeoff.
This protects not only against memset()-s, but against "near" wild
pointers too, and makes more probable to catch "distant" ones.

The core file of the set is included into the C-file, not complied
separately in order to enable (potential) coexisting of
mcheck-protectors, e.g. malloc_simple(.) and dlmalloc simultaneously.

My tests were for ARM SoC, 64bit, so the patch is
aware of alignment.

Primary this patch is for using by developers: to verify,
if a change doesn't break the heap integrity.
By default the mcheck is disabled and wouldn't affect the boot.

I used pedantic mode, canary=16byte, registry-size=6608.
For my system the overhead was 230ms.

63f6a449bf usb: kbd: Add probe quirk for Apple and Keychron keyboards
Those keyboards do not return the current device state. Polling will
timeout unless there are key presses. This is not a problem during
operation but the initial device state query during probing will fail.
Skip this step in usb_kbd_probe_dev() to make these devices useable.
Not all Apple keyboards behave like this. A keyboard with USB
vendor/product ID 05ac:0221 is reported to work with the current code.
Unfortunately some Keychron keyboards "re-use" Apple's vendor ID and
show the same behavior (Keychron C2, 05ac:024f for example).

Add the environment variable "usb_ignorelist" to prevent USB devices
listed in it from being bound to drivers. This allows to ignore devices
which are undesirable or trigger bugs in u-boot's USB stack.
Devices emulating keyboards are one example of undesirable devices as
u-boot currently supports only a single USB keyboard device. Most
commonly, people run into this with Yubikeys, so let's ignore those in
the default environment.

Based on previous USB keyboard specific patches for the same purpose.

Additionally, fix a potential uninitialised variable use caught by these
tests, the btn variable in get_button_cmd() is assumed to be null if
button_get_by_label() fails, but it's actually used uninitialised in
that case.

CONFIG_BUTTON is now enabled automatically and was removed when running

Return value of a function 'malloc_cache_aligned'
is dereferenced at autoboot.c:207 without checking for NULL,
but it is usually checked for this function.

39162d9348 log: fixup log_head after relocating global data
When `gd` is relocated during `spl_relocate_stack_gd()` the
doubly-linked circular list in the `log_head` member is broken.

The last element of the list should point back to the initial
`list_head`, but as the initial `list_head` is moved the pointer becomes
stale. As a result the loop in `log_dispatch` would never finish.

ARCH_NEXELL: Change calculation of monitor length (gd->mon_len) to fix
relocation at boards with s5p4418-SoC (ARCH_NEXELL). At s5p4418, _start
is after the header (NSIH). Therefore the monitor length has to be
calculated using __image_copy_start instead of _start in order the
whole monitor code is relocated.

ea3348ebc2 Merge patch series "Handoff bloblist from previous boot stage"
Raymond Mao <raymond.mao@linaro.org> says:

This patch set adds/adapts a few bloblist APIs and implements Arm arch
custom function to retrieve the bloblist (aka. Transfer List) from
previous loader via boot arguments when BLOBLIST option is enabled and
all boot arguments are compliant to the register conventions defined
in the Firmware Handoff spec v0.9.

If an arch wishes to have different behaviors for loading bloblist
from the previous boot stage, it is required to implement the custom
function xferlist_from_boot_arg().

66131310d8 bloblist: Load the bloblist from the previous loader
During bloblist initialization, load the bloblist via boot arguments
from the previous loader.
If a valid bloblist exists in boot arguments, relocate it into the
fixed bloblist memory region.
If not, fallback to support BLOBLIST_ADDR or BLOBLIST_ALLOC.

1ef43f3bf2 bloblist: refactor of bloblist_reloc()
The current bloblist pointer and size can be retrieved from global
data, so we don't need to pass them from the function arguments.
This change also help to remove all external access of gd->bloblist
outside of bloblist module.

6725421493 bloblist: check bloblist with specified buffer size
Instead of expecting the bloblist total size to be the same as the
pre-allocated buffer size, practically we are more interested in
whether the pre-allocated buffer size is bigger than the bloblist
total size.

08e2cd6cd3 common: usb-hub: Reset USB 3.0 hubs only
Additional testing of the changes introduced in commit 33e06dcbe5 "common:
usb-hub: Reset hub port before scanning") revealed that some USB 2.0 and 3.0
flash drives didn't work in U-Boot on some Allwinner SoCs that support USB
2.0 interfaces only.  More precisely, some of the tested USB 2.0 and 3.0
flash drives failed to be detected and work on an OrangePi Zero 3, based on
the Allwinner H616 SoC that supports USB 2.0 only, while the same USB flash
drives worked just fine on a Pine64 H64, based on the Allwinner H6 SoC that
supports both USB 2.0 and USB 3.0 interfaces.

The USB ID of the above-mentioned USB 3.0 flash drive that failed to work is
1f75:0917 (Innostor Technology Corporation IS917 Mass storage), it is 32 GB
in size and sold under the PNY brand.  The mentioned USB 2.0 drive is some
inexpensive no-name drive with an invalid USB ID.

Resetting USB 3.0 hubs only, which this patch introduces to the USB hub
resets, has been tested to work as expected, resolving the identified issues
on the Allwinner H616, while not introducing any new issues on other tested
Allwinner SoCs.  Thus, let's fix it that way.

According to the USB 3.0 specification, resetting a USB 3.0 port is required
when an attached USB device transitions between different states, such as
when it resumes from suspend.  Though, the Linux kernel performs additional
USB 3.0 port resets upon initial USB device attachment, as visible in commit
07194ab7be63 ("USB: Reset USB 3.0 devices on (re)discovery") in the kernel
source, to ensure proper state of the USB 3.0 hub port and proper USB mode
negotiation during the initial USB device attachment and enumeration.

These additional types of USB port resets don't exist for USB 2.0 hubs,
according the USB 2.0 specification.  The resets seem to be added to the USB
3.0 specification as part of the port and device mode negotiation.

The Linux kernel resets USB 3.0 (i.e. SuperSpeed) hubs only, as visible in
commit 10d674a82e55 ("USB: When hot reset for USB3 fails, try warm reset.")
in the kernel source.  The check for SuperSpeed hubs is performed in a way
that also applies to newer SuperSpeed Plus (USB 3.1 or 3.2) hubs as well,
which hopefully makes it future proof.
