Hey all,
This is a v3 of Simon's series[1] and depends on the series[2] I posted
the other day that removes <env.h> from <command.h>. With this series
done, I believe we've tackled all of the current cases of headers which
include <env.h> without directly needing it. Much of this series is in
fact Simon's v2 with the main differneces being:
- Removing <env.h> from <net.h> at the end
- Removing env_to_ip() given how little it's used rather than shuffling
around where it's declared and un-inline'ing it. For a rarely used
helper, this ends up being cleaner I think. Especially looking at some
of the users (which called env_get repeatedly). If there's strong
opinion here about using the other method[3] we can do that instead.
- Setting aside for now how to handle CMD_ELF=y and NO_NET=y because
today it's actually fine as we unconditionally build lib/net_utils.c
where string_to_ip() is defined. I'm unsure if a further series is
warranted here or not. We rely on link-time optimization to keep code
readable too.

Now that env_get_ip() has been removed, the include file <net.h> does
not need anything from <env.h>. Furthermore, include/env.h itself
includes other headers which can lead to longer indirect inclusion
paths. To prepare to remove <env.h> from <net.h> fix all of the
remaining places which had relied on this indirect inclusion to instead
include <env.h> directly.

Given Simon's series at [1] I started looking in to what brings in
<env.h> when not strictly required and in turn has some unintended
implicit includes. This series takes care of the places where, commonly,
<linux/string.h> or <env.h> itself were required along with a few other
less common cases. This sets aside for the moment what to do about
net-common.h and env_get_ip() as I'm not entirely sure what's best
there.

This started as a rather simple patch, 1/12, adding the ability to
more conveniently do regex matching in shell.
But with that, it became very easy to see what the slre library can
and especially what it cannot do, and that way I found both outright
bugs and a "wow, doesn't it support that syntax" gotcha. I couldn't
find any tests ('git grep slre -- test/' was empty), so I added a
small test suite and tweaked slre.c.

CONFIG_VIDEO_COPY implemented a range-based copying mechanism: If we
print a single character, it will always copy the full range of bytes
from the top left corner of the character to the lower right onto the
uncached frame buffer. This includes pretty much the full line contents
of the printed character.
Since we now have proper damage tracking, let's make use of that to reduce
the amount of data we need to copy. With this patch applied, we will only
copy the tiny rectangle surrounding characters when we print them,
speeding up the video console.
After this, changes to the main frame buffer are not immediately copied
to the copy frame buffer, but postponed until the next video device
sync. So issue an explicit sync before inspecting the copy frame buffer
contents for the video tests.

The video tests have a helper function to generate a pseudo-digest of
frame buffer contents, but it only does so for the main one. There is
another check that the copy frame buffer is the same as that. But
neither is enough to test if only the modified regions are copied to the
copy frame buffer, since we will want the two to be different in very
specific ways.
Add a boolean argument to the existing helper function to indicate which
frame buffer we want to inspect, and update the existing callers.

While checking frame buffer contents, the video tests also check if the
copy frame buffer contents match the main frame buffer. To test if only
the modified regions are updated after a sync, we will need to create
situations where the two are mismatched. Split this check into another
function that we can skip calling, since we won't want it to error on
those mismatched cases.

It is very surprising that such an uclass, specifically designed to
handle resources that may be shared by different devices, is not keeping
the count of the number of times a power domain has been
enabled/disabled to avoid shutting it down unexpectedly or disabling it
several times.
Doing this causes troubles on eg. i.MX8MP because disabling power
domains can be done in recursive loops were the same power domain
disabled up to 4 times in a row. PGCs seem to have tight FSM internal
timings to respect and it is easy to produce a race condition that puts
the power domains in an unstable state, leading to ADB400 errors and
later crashes in Linux.
Some drivers implement their own mechanism for that, but it is probably
best to add this feature in the uclass and share the common code across
drivers. In order to avoid breaking existing drivers, refcounting is
only enabled if the number of subdomains a device node supports is
explicitly set in the probe function. ->xlate() callbacks will return
the power domain ID which is then being used as the array index to reach
the correct refcounter.
As we do not want to break existing users while stile getting
interesting error codes, the implementation is split between:
- a low-level helper reporting error codes if the requested transition
could not be operated,
- a higher-level helper ignoring the "non error" codes, like EALREADY and
EBUSY.
CI tests using power domains are slightly updated to make sure the count
of on/off calls is even and the results match what we *now* expect. They
are also extended to test the low-level functions.

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:
