Rasmus Villemoes <ravi@prevas.dk> says:
While looking through list.h, I saw that the regular list_* helpers
(and one of the hlist_* ones) still contain the prefetch() that was
removed in linux 14 years ago. It doesn't do anything, but makes the
macros harder to read, so get rid of it, and the fallback, no-op
definition that they relied on. That requires removing a few uses
outside list.h as well.
checkpatch warns about some whitespace issues in list.h, but as I've
copied whole kerneldoc+#define blocks directly from the linux kernel,
I think it's better to just accept that so that we don't introduce
needless diffs. The "macro argument reuse" arguments should also be
ignored, as e.g. the "member" arguments are obviously always just bare
identifiers, and the "pos" arguments must be assigned to multiple
times.

These all end up using the no-op prefetch() defined in linux/list.h,
because the only possible real implementation is in
arch/mips/include/asm/processor.h, which is behing
CONFIG_CPU_HAS_PREFETCH which is nowhere defined.
In order to be able to drop that fallback definition from list.h,
first remove all uses.

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.

This patch merges flush and reset logic for both host and gadget code
into a common set of functions, reducing duplication. It also adds support
for the updated reset logic to compatible with core version since v4.20a.
This patch mainly refers to the patch in the kernel.

The ULPI_UTMI_SEL bit in the DWC2 driver was set incorrectly. According
to the datasheet [1], this bit should be set to 0 for UTMI interface and 1
for ULPI interface. The existing code had this logic reversed,
causing the interface selection to be incorrect.
This commit corrects the ULPI_UTMI_SEL bit setting to match the
datasheet's description. Referencing the kernel's code [2] also confirms
this fix.

The way we enable ULPI support today isn't something that should work.
The "optional" keyword in a choice statement is not a documented
feature. To make this work in a supported way, make USB_ULPI something
we ask about if USB_HOST is set. Next, we move the choice of what
viewer to use to be after the framework portion and to depend on that.
We then borrow a few words from the top-level README to make the help
text here clearer. Finally we make the Qualcomm driver select ULPI as
it's required and we make the tegra driver not duplicate a check that
Kconfig now handles for us.

dwc3_core_init loops 'timeout' times to check if the IP block is out
of reset using 'while (timeout--)'. If there is some issue and
the block doesn't come out of reset, the loop will run till
'timeout' becomes zero and the post decrement operator would set
timeout to 0xffffffff. Though the IP block is not out reset, the
subsequent if check 'if !timeout' would fail as timeout is not
equal to zero and the function proceeds with the initialization.
Use poll API instead to resolve this.

Jerome Forissier <jerome.forissier@linaro.org> says:
This series introduces threads and uses them to improve the performance
of the USB bus scanning code and to implement background jobs in the
shell via two new commands: 'spawn' and 'wait'.
The threading framework is called 'uthread' and is inspired from the
barebox threads [2]. setjmp() and longjmp() are used to save and
restore contexts, as well as a non-standard extension called initjmp().
This new function is added in several patches, one for each
architecture that supports HAVE_SETJMP. A new symbol is defined:
HAVE_INITJMP. Two tests, one for initjmp() and one for the uthread
scheduling, are added to the lib suite.
After introducing threads and making schedule() and udelay() a thread
re-scheduling point, the USB stack initialization is modified to benefit
from concurrency when UTHREAD is enabled, where uthreads are used in
usb_init() to initialize and scan multiple busses at the same time.
The code was tested on arm64 and arm QEMU with 4 simulated XHCI buses
and some devices. On this platform the USB scan takes 2.2 s instead of
5.6 s. Tested on i.MX93 EVK with two USB hubs, one ethernet adapter and
one webcam on each, "usb start" takes 2.4 s instead of 4.6 s.
Finally, the spawn and wait commands are introduced, allowing the use of
threads from the shell. Tested on the i.MX93 EVK with a spinning HDD
connected to USB1 and the network connected to ENET1. The USB plus DHCP
init sequence "spawn usb start; spawn dhcp; wait" takes 4.5 seconds
instead of 8 seconds for "usb start; dhcp".

Use the uthread framework to initialize and scan USB buses in parallel
for better performance. The console output is slightly modified with a
final per-bus report of the number of devices found, common to UTHREAD
and !UTHREAD. The USB tests are updated accordingly.
Tested on two platforms:
1. arm64 QEMU on a somewhat contrived example (4 USB buses, each with
one audio device, one keyboard, one mouse and one tablet)
$ make qemu_arm64_defconfig
$ make -j$(nproc) CROSS_COMPILE="ccache aarch64-linux-gnu-"
$ qemu-system-aarch64 -M virt -nographic -cpu max -bios u-boot.bin \
$(for i in {1..4}; do echo -device qemu-xhci,id=xhci$i \
-device\ usb-{audio,kbd,mouse,tablet},bus=xhci$i.0; \
done)
2. i.MX93 EVK (imx93_11x11_evk_defconfig) with two USB hubs, each with
one webcam and one ethernet adapter, resulting in the following device
tree:

However, right now acm_stdio_stop() does not completely undo
acm_stdio_start(): The USB gadget is unregistered, but as long as dev->priv
stays set acm_stdio_start() will never register the USB gadget again.
Clear dev->priv after we detach to make sure a start operation after a stop

U-Boot has an older version of the Linux gadget API, where USB endpoints
returned by usb_ep_autoconfig() are not automatically claimed. As written
in the documentation comment:
"To prevent the endpoint from being returned by a later autoconfig call,
claim it by assigning ep->driver_data to some non-null value."
Right now f_acm doesn't do that, which means that e.g. ep_in and ep_notify
may end up being assigned the same endpoint. Surprisingly, the ACM console
is still somehow working, but this is not the expected behavior. It will
break with a later commit that disallows calling usb_ep_enable() multiple
times.
Fix this by assigning some data to ep->driver_data, similar to the other
gadget drivers.

Resetting CPU ...
This happens when fsg_common_init() fails to allocate memory and calls
fsg_common_release().
fsg_common_release() then calls kfree() which frees common->luns.
However, common->luns was never allocated via kmalloc/calloc(),
resulting in a crash.
Drop the invalid kfree. The memory from common->luns will be
reclaimed when we kfree(common) later in fgs_common_release().

The kref structure is locally to f_mass_storage and is not used
anywhere beside in fsg_common_release().
Remove it and use struct fsg_common* instead.

Andre Przywara <andre.przywara@arm.com> says:
C's implicit fallthrough behaviour in switch/case statements can lead to
subtle bugs. Quite some while ago many compilers introduced warnings in
those cases, requiring intentional fallthrough's to be annotated.
So far we were not enabling that compiler option, so many ambiguities
and some bugs in the code went unnoticed.
This series adds the required annotations in code paths that the first
stage of the U-Boot CI covers. There is a large number of cases left
in the libbz2 code. The usage of switch/case is borderline insane there,
labels are hidden in macros, and there are no breaks, but just goto's.
Upstream still uses very similar code, without any annotations. I still
am not 100% sure those are meant to fall through or not, and plan to do
further investigations, but didn't want to hold the rest of the patches
back. You can see for yourself by applying patch 18/18 and building for
sandbox64, for instance.
Because of this we cannot quite enable the warning in the Makefile yet,
but those fixes are worth regardless, and be it to increase readability.
Please note that those patches do not fix anything, really, they just add
those fallthrough annotations, so the series is not really critical.

The USB XHCI code uses an implicit switch/case fallthrough to share code
for handling full speed and low speed transfers.
Add our "fallthrough;" statement-like macro before the second label in
the XHCI code, to avoid a warning when GCC's -Wimplicit-fallthrough
warning option is enabled.

Even though we seem to catch POWEROFF and EFSCLEAR commands in the THOR
protocol request handling, we ultimately do not seem to handle them
(apart from sending a response), so those commands still print an error
message.
Annotate the switch/case fallthrough in this case, to make this clear to
the compiler.

empty/full"
Simon Glass <sjg@chromium.org> says:
The membuff implementation curently has no tests. It also assumes that
head and tail can never correspond unless the buffer is empty.
This series provides a compile-time flag to support a 'full' flag. It
also adds some tests of the main routines.
The data structure is also renamed to membuf which fits better with
U-Boot.
There may be some cases in the code which could be optimised a little,
but the implementation is functional.

The UUU tool excepts the interrupt-in endpoint to be ep1in, otherwise
it crashes. This is a result of the previous hard-coded EP setup in
drivers/usb/gadget/epautoconf.c which did special-case EP allocation
for SPL builds, and which was since converted to this callback, but
without the special-case EP allocation in SPL part.
This reinstates the SPL part in an isolated manner, only for NXP iMX
SoCs, only for SPL builds, and only for the ep1in interrupt-in endpoint.
