EHCI is usually used with companion controller (like OHCI) as companion
controller. This information on the companion is missing currently in

So, if the usb-uclass isn't aware, it may scan busses in any order: OHCI
first, then EHCI.
This is seen on STM32MP1 where DT probing makes the probe order to occur
by increasing address (OHCI address < EHCI address).
When a low speed or full-speed device is plugged in, it's not detected as
EHCI should first detect it, and give ownership (handover) to OHCI.

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

For boards without EVENT enabled the growth is smaller, e.g. nokia_rx51:

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.

Reset gd->cur_serial_dev pointer to avoid calling non-relocated code

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().

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

the signature node containing the capsule public key in the platform's

Corresponding changes have also been made to the test setup of the EFI

sandbox: capsule: Add path to the public key ESL file
Add the path to the public key EFI Signature List(ESL) file for the
sandbox variants which enable capsule authentication. This ESL file
gets embedded into the platform's device-tree as part of the build.

scripts/Makefile.lib: Embed capsule public key in platform's dtb
The EFI capsule authentication logic in u-boot expects the public key
in the form of an EFI Signature List(ESL) to be provided as part of
the platform's dtb. Currently, the embedding of the ESL file into the
dtb needs to be done manually.
Add a target for generating a dtsi file which contains the signature
node with the ESL file included as a property under the signature
node. Include the dtsi file in the dtb. This brings the embedding of
the ESL in the dtb into the U-Boot build flow.
The path to the ESL file is specified through the
CONFIG_EFI_CAPSULE_ESL_FILE symbol.
