Currently, we must call cyclic_init() at some point before
cyclic_register() becomes possible. That turns out to be somewhat
awkward, especially with SPL, and has resulted in a watchdog callback
not being registered, thus causing the board to prematurely reset.
We already rely on gd->cyclic reliably being set to NULL by the asm
code that clears all of gd. Now that the cyclic list is a hlist, and
thus an empty list is represented by a NULL head pointer, and struct
cyclic_drv has no other members, we can just as well drop a level of
indirection and put the hlist_head directly in struct
global_data. This doesn't increase the size of struct global_data,
gets rid of an early malloc(), and generates slightly smaller code.
But primarily, this avoids having to call cyclic_init() early; the cyclic
infrastructure is simply ready to register callbacks as soon as we
enter C code.
We can still end up with schedule() being called from asm very early,
so we still need to check that gd itself has been properly initialized
[*], but once it has, gd->cyclic_list is perfectly fine to access, and
will just be an empty list.
As for cyclic_uninit(), it was never really the opposite of
cyclic_init() since it didn't free the struct cyclic_drv nor set
gd->cyclic to NULL. Rename it to cyclic_unregister_all() and use that
in test/, and also insert a call at the end of the board_init_f
sequence so that gd->cyclic_list is a fresh empty list before we enter
board_init_r().
A small piece of ugliness is that I had to add a cast in
cyclic_get_list() to silence a "discards 'volatile' qualifier"
warning, but that is completely equivalent to the existing handling of
the uclass_root_s list_head member.
[*] I'm not really sure where we guarantee that the register used for
gd contains 0 until it gets explicitly initialized, but that must be
the case, otherwise testing gd for being NULL would not make much sense.

A hlist is headed by just a single pointer, so can only be traversed
forwards, and insertions can only happen at the head (or before/after
an existing list member). But each list node still consists of two
pointers, so arbitrary elements can still be removed in O(1).
This is precisely what we need for the cyclic_list - we never need to
traverse it backwards, and the order the callbacks appear in the list
should really not matter.
One advantage, and the main reason for doing this switch, is that an
empty list is represented by a NULL head pointer, so unlike a
list_head, it does not need separate C code to initialize - a
memset(,0,) of the containing structure is sufficient.
This is mostly mechanical:
- The iterators are updated with an h prefix, and the type of the
temporary variable changed to struct hlist_node*.
- Adding/removing is now just hlist_add_head (and not tail) and
hlist_del().
- struct members and function return values updated.

We're already relying on gd->cyclic being NULL before cyclic_init() is
called - i.e., we're relying on all of gd being zeroed before entering
any C code. And when we do populate gd->cyclic, its ->cyclic_ready
member is automatically set to true. So we can actually just rely on
testing gd->cyclic itself.
The only wrinkle is that cyclic_uninit() actually did set
->cyclic_ready to false. However, since it doesn't free gd->cyclic,
the cyclic infrastructure is actually still ready (i.e., the list_head
is properly initialized as an empty list).

The FWU Multi Bank Update feature supports updating firmware images
to one of multiple sets(also called banks) of images. The firmware
images are clubbed together in banks, with the system booting images
from the active bank. Information on the images such as which bank
they belong to is stored as part of the metadata structure, which is
stored on the same storage media as the firmware images on a dedicated
partition.
At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

The FWU Multi Bank Update specification requires the Update Agent to
carry out certain checks at the time of platform boot. The Update
Agent is the component which is responsible for updating the firmware
components and maintaining and keeping the metadata in sync.
The spec requires that the Update Agent perform the following checks
at the time of boot
* Sanity check of both the metadata copies maintained by the platform.
* Get the boot index passed to U-Boot by the prior stage bootloader
and use this value for metadata bookkeeping.
* Check if the system is booting in Trial State. If the system boots
in the Trial State for more than a specified number of boot counts,
change the Active Bank to be booting the platform from.
Call these checks through the main loop event at the time of platform
boot.

Checks done in C are orders of magnitude faster and it is possible to get

the command line.
The model is to have a Python test set up some things and then use C code
(in a unit test) to check that they were done correctly. But we don't want
those checks to happen as part of normal test running, since each C unit
tests is dependent on the associate Python tests, so cannot run without
it.
To acheive this, add a new UT_TESTF_MANUAL flag to use with the C 'check'

Merge tag 'video-20221030' of https://source.denx.de/u-boot/custodians/u-boot-video
- fix [hv]sync active vs back porch in dw_mipi_dsi
- simplefb rotation support
- support splash as raw image from MMC
- enhancements to Truetype console (multiple fonts and sizes)
- drop old LCD support
This option should not have the SYS_ in it. Drop it so it fits in with the
other video options.
Also simplify the alignment code in gunzip_bmp(), since malloc() always
returns a 32-bit-aligned pointer.

This is not as simple as it seems. Add a function to provide it so that
the upcoming menu feature can space lines out correctly.

Add a new 'font' command which allows the fonts to be listed as well as
selecting a different font and size.
Allow the test to run on sandbox, where multiple font/size combinations
are supported, as well as sandbox_flattree, where they are not.

It is useful to be able to support multiple fonts. Add a function to
handle this as well as one to list the available fonts.

At present these are attached to vidconsole which means that the video
uclass requires that a console is enabled. This is not the intention.
The colours are a reasonable way of indexing common colours in any case,
so move them to the video uclass instead.
Rename vid_console_color() to video_index_to_colour() now that it is more
generic. Also fix the inconsistent spelling in these functions.

When probing a device fails NULL pointer is returned, and following
devices in uclass list cannot be iterated. Skip to next device on error
instead.
With that the only condition under which these simple iteration
functions return error is when the dm is not initialized at uclass_get
time. This is not all that interesting, change return type to void.

The GPMC is a unified memory controller dedicated for interfacing
with external memory devices like
- Asynchronous SRAM-like memories and ASICs
- Asynchronous, synchronous, and page mode burst NOR flash
- NAND flash
- Pseudo-SRAM devices
This driver will take care of setting up the GPMC based on
the settings specified in the Device tree and then
probe its children.

OMAP3 BeagleBoard NAND boot hangs when spl_load_legacy_img() tries
to read the header into 'struct hdr' which is allocated on the
stack.
As the header has already been read once before by spl_nand.c,
we can avoid the extra header allocation and read here by
simply passing around the pointer to the header.
This fixes NAND boot on OMAP3 BeagleBoard.

With the migration of the watchdog infrastructure to cyclic functions
it's been noticed, that at least one watchdog driver is broken now. As
the execution time of it's watchdog reset function is quite long.
In general it's not really necessary (right now) to disable the cyclic
function upon exceeding CPU time usage. So instead of disabling the
cylic function in this case, let's just print a warning once to show
this potential problem to the user.

In order to test that U-Boot actually maintains the watchdog device(s)
during long-running busy-loops, such as those where we wait for the
user to stop autoboot, we need a watchdog device that actually does
something during those loops; we cannot test that behaviour via the DM
test framework.
So introduce a relatively simple watchdog device which is simply based
on calling the host OS' alarm() function; that has the nice property
that a new call to alarm() simply sets a new deadline, and alarm(0)
cancels any existing alarm. These properties are precisely what we
need to implement start/reset/stop. We install our own handler so that
we get a known message printed if and when the watchdog fires, and by
just invoking that handler directly, we get expire_now for free.
The actual calls to the various OS functions (alarm, signal, raise)
need to be done in os.c, and since the driver code cannot get access
to the values of SIGALRM or SIG_DFL (that would require including a
host header, and that's only os.c which can do that), we cannot simply
do trivial wrappers for signal() and raise(), but instead create
specialized functions just for use by this driver.
Apart from enabling this driver for sandbox{,64}_defconfig, also
enable the wdt command which was useful for hand-testing this new
driver (especially with running u-boot under strace).
