To quote the author:
This series replaces some more of the init hooks in board_f.c and
board_r.c with events. Notably it converts last_state_init() over.
It also provides a 'simple' event spy, which takes no arguments. It
turns out that this is quite a common case, so it is worth optimising
for this, to reduce code size, before events become too commonly used.
Finally, it introduces a way of emitting an event in an initcall,
instead of calling a function. This is likely to be used at least as
often as the functions, as we convert more of these initcalls.
As part of this, the initcall code is brought back into a C file. Somehow
the compiler has changed or something else, so that this does not confer
any benefits now.
For boards with EVENT enabled, this unfortunately results in small
growth, e.g. for firefly:
aarch64: (for 1/1 boards) all +114.0 data +16.0 rodata +22.0 text +76.0
arm: (for 1/1 boards) all +82.0 rodata +18.0 text +64.0
For boards without EVENT enabled the growth is smaller, e.g. nokia_rx51:
arm: (for 1/1 boards) all +32.0 data +8.0 rodata -8.0 text +32.0
I cannot find a good way to avoid the latter, other than macro magic
with an embedded comma (to completely remove an event entry), which
seems nasty.

the function to use the new event instead.
Make sure that EVENT is enabled by affected boards, by selecting it from

initcall: Support emitting events
At present the initcall list consists of a list of function pointers. Over
time the initcall lists will likely change to mostly emitting events,
since most of the calls are board- or arch-specific.
As a first step, allow an initcall to be an event type instead of a
function pointer. Add the required macro and update initcall_run_list() to
emit an event in that case, or ignore it if events are not enabled.
The bottom 8 bits of the function pointer are used to hold the event type,
with the rest being all ones. This should avoid any collision, since
initcalls should not be above 0xffffff00 in memory.
Convert misc_init_f over to use this mechanism.
Add comments to the initcall header file while we are here. Also fix up
the trace test to handle the change.

serial-uclass: reset gd->cur_serial_dev to NULL if serial not found
Reset gd->cur_serial_dev pointer to avoid calling non-relocated code
from relocated code if a serial driver is not found and
CONFIG_REQUIRE_SERIAL_CONSOLE is disabled.
Here is detailed explanation of what this patch is trying to fix.
U-boot calls the serial_find_console_or_panic() function twice.
The first console setup occurs before U-boot relocation in
the serial_init(). This stage uses simple FDT parsing and
assigns gd->cur_serial_dev to a "serial" device that lives in
non-relocated code too.
The second console setup after U-boot relocation(from serial_initialize())
may use full live DT (if OF_LIVE enabled) probe sequence with buses,
clocks, resets, etc... And if the console setup fails at this step,
than we should be caught by panic_str("No serial driver found").
But... If we disable CONFIG_REQUIRE_SERIAL_CONSOLE, than we
return from serial_init() with gd->cur_serial_dev pointing
to the "old"(non-relocated) serial device.
And if this area, where "old" serial device is placed, is changed
(e.g. Linux kernel may be relocated at this address), than we will get
an unexpected crash on the next call of printf().

pci: pcie-brcmstb: do not rely on CLKREQ# signal
When the Broadcom STB PCIe controller is initialized, it must be set
into one of three CLKREQ# modes: "none"/"aspm"/"l1ss". The Linux driver,
through today, hard-codes "aspm" since the vast majority of boards using
this driver have a fixed PCIe bus with the CLKREQ# signal wired up.
The Raspberry Pi CM4, however, can be connected to a plethora of PCIe
devices, some of which do not connect the CLKREQ# line (they just leave
it floating). So "aspm" mode is no longer appropriate in all cases. In
Linux, there is a proposed patchset [1] to determine the proper mode.
This doesn't really make sense in U-Boot's case, so we just change the
assumption from "aspm" to "none" (which is always safe).
This patch DOES resolve a real-world crash that occurs when U-Boot is
running on a Raspberry Pi CM4 installed in slot 3 of a Turing Pi 2

Merge branch '2023-08-24-enable-more-features-in-qemu-arm' into next
To quote the author:
Now that the driver for the Bochs VGA card emulated by QEMU is no longer
limited to x86 architectures, this series enables it on arm and arm64 virtual
machines to provide a graphical interface. In line with that series this also
enables console buffering and USB keyboard.
Tested with the Debian 12 installer using GRUB EFI:
doc: qemu: arm: Add a section on booting Linux distros
Add an example qemu-system-aarch64 command that can make U-Boot on QEMU
boot into the Debian Installer, along with resulting console messages
from U-Boot, based on the existing documentation section for the x86
version.
