Add a new function fdt_copy_fixed_partitions to copy the fixed
partition nodes from U-Boot device tree to Linux kernel
device tree and to dynamically configure the MTD partitions.
This function fdt_copy_fixed_partitions is only based on device tree
with livetree compatible function and replace the function
fdt_fixup_mtdparts based on mtdparts variable.

- it fails to store (and thus echo) the last character of the invalid

- it fails to set esc_len to 0 when it finishes emitting the invalid
sequence, meaning that the following character will appear to be part
of a new escape sequence
- it processes the first character of the rejected sequence as a valid
character, just starting the sequence all over again

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to

where select is appropriate. Audit the current users of EVENT_SPY to

To quote the author:
So far standard boot lacks a boot menu, although it is possible to create
a rudimentary one using the existing 'bootmenu' command.
Even then, this text-based menu offer only basic functionality and does
not take full advantage of the displays which are common on many devices.
This series provides a 'bootflow menu' command which allows the user to
select from the available bootflows. An attempt is made to show the name
of the available operating systems, by reading more information into the
bootflow. A logo can be read also, where supported, so that this can be
presented to the user when an option is highlighted.
Full use is made of TrueType fonts, if enabled. For cases where only a
serial console is available, it falls back to a simple text-based menu.
All of this is implementing using a new 'expo' construct, a collection of
scenes (like menu screens) which can be navigated by the user to view
information and select options. This is fairly general and should be able
to cope with a wider array of use cases, with less hacking of the menu
code, such as is currently needed for CMD_BOOTEFI_BOOTMGR.
Of course it would be possible to enhance the existing menu rather than
creating a new setup. Instead it seems better to make the existing menu
use expo, if code space permits. It avoids the event-loop problem and
should be more extensible, given its loosely coupled components and use of
IDs instead of pointers. Further motivation is provided in the
documentation.
For now the CLI keypress-decoding code is split out to be used by the new
menu. The key codes defined by menu.h are reused also.
This is of course just a starting point. Some ideas for future work are
included in the documentation.
We should use the cmd/ directory for commands rather than for common code
used elsewhere in U-Boot. Move the common 'source' code into
image-board.c to achieve this.
The image_source_script() function needs to call run_command_list() so
seems to belong better in the command library. Move and rename it.

The current cread_line() function is very long. It handles the escape
processing inline. The menu command does similar processing but at the
character level, so there is some duplication.
Split the character processing into a new function cli_ch_process() which
processes individual characters and returns the resulting input character,
taking account of escape sequences. It requires the caller to set up and
maintain its state.
Update cread_line() to use this new function.
The only intended functional change is that an invalid escape sequence
does not add invalid/control characters into the input buffer, but instead
discards these.

Add a new CONFIG_USB_HUB_DEBOUNCE_TIMEOUT to increase the
HUB_DEBOUNCE_TIMEOUT value, for example to 2s because some usb device
needs around 1.5s or more to make the hub port status to be
connected steadily after being powered off and powered on.
This 2s value is aligned with Linux driver and avoids to configure
"usb_pgood_delay" as a workaround for connection timeout on
some USB device; normally the env variable "usb_pgood_delay" is used
to delay the first query after power ON and thus the device answer,
but this variable not used to increase the connection timeout delay.

The main issue the driver addresses is that a USB hub needs to be
powered before it can be discovered. This is often solved by using
"regulator-always-on".
This driver is inspired by the Linux v6.1 driver. It only enables (or
disables) the hub vdd (3v3) supply, so it can be enumerated.
Scanning of the device tree is done in a similar manner to the sandbox,
by the usb-uclass. DT part looks like:
&usbh_ehci {
...
#address-cells = <1>;
#size-cells = <0>;
hub@1 {
compatible = "usb424,2514";
reg = <1>;
vdd-supply = <&v3v3>;
};
};
When the bus gets probed, the driver is automatically probed/removed from
the bus tree, as an example on stm32:
STM32MP> usb start
starting USB...
STM32MP> dm tree
Class Index Probed Driver Name
-----------------------------------------------------------

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).

This is inconvenient since we sometimes want to provide several

Beside some rather unexciting sync of the DTs from the kernel tree, and
some Kconfig cleanup, there are some improvements for the ARMv5 Allwinner
family, to support boards with the F1C200s (64MB DRAM) better. We will
get actual board support as soon as the DTs have passed the Linux review
process.
There is also support for the X96 Mate TV Box, featuring the H616 SoC and
a full 4GB of DRAM.
Also we found the secret to enable SPI booting on the H616 (pin PC5 must
be pulled to GND), so the SPI boot support patch is now good to go.
Passed the gitlab CI, plus briefly tested on Pine64-LTS, LicheePi Nano,
X96 Mate and OrangePi Zero.
Some configuration symbols formerly defined in header files were
recently converted to Kconfig symbols. This moved their value definition
into *every* defconfig file, even though those values are hardly board
choices.
Use the new Kconfig option to define per-SoC default values, in just one
place, which makes the definition in each defconfig file redundant.
We refrain from setting a sunxi specific value for CONFIG_SYS_BOOTM_LEN,
so this defaults to a much better 64MB for uncompressed arm64 kernels.

broken when one has an external always-running watchdog device with a

WATCHDOG_RESET() in the loops where we wait for the bootdelay to

This is done implicitly in the !AUTOBOOT_KEYED case,

udelay(10000), and udelay() does a WATCHDOG_RESET().

A recurring theme on LKML is the boot process deadlocking due to some
process blocking waiting for random numbers, while the kernel's
Cryptographic Random Number Generator (crng) is not initalized yet,
but that very blocking means no activity happens that would generate
the entropy necessary to finalize seeding the crng.
This is not a problem on boards that have a good hwrng (when the
kernel is configured to trust it), whether in the CPU or in a TPM or
elsewhere. However, that's far from all boards out there. Moreover,
there are consumers in the kernel that try to obtain random numbers
very early, before the kernel has had any chance to initialize any
hwrng or other peripherals.
Allow a board to provide a board_rng_seed() function, which is
responsible for providing a value to be put into the rng-seed property
under the /chosen node.
The board code is responsible for how to actually obtain those
bytes.
- One possibility is for the board to load a seed "file" from
somewhere (it need not be a file in a filesystem of course), and
then ensure that that the same seed file does not get used on
subsequent boots.
* One way to do that is to delete the file, or otherwise mark it as
invalid, then rely on userspace to create a new one, and living
with the possibility of not finding a seed file during some boots.
* Another is to use the scheme used by systemd-boot and create a new
seed file immediately, but in a way that the seed passed to the
kernel and the new (i.e. next) seed cannot be deduced from each
other, see the explanation at
https://lore.kernel.org/lkml/20190929090512.GB13049@gardel-login/
and the current code at
https://github.com/systemd/systemd/blob/main/src/boot/efi/random-seed.c
- The board may have an hwrng from which some bytes can be read; while
the kernel can also do that, doing it in U-Boot and providing a seed
ensures that even very early users in the kernel get good random
numbers.
- If the board has a sensor of some sort (temperature, humidity, GPS,
RTC, whatever), mixing in a reading of that doesn't hurt.
- etc. etc.
These can of course be combined.
The rng-seed property is mixed into the pool used by the linux
kernel's CRNG very early during boot. Whether it then actually
contributes towards the kernel considering the CRNG initialized
depends on whether the kernel has been configured with
CONFIG_RANDOM_TRUST_BOOTLOADER (nowadays overridable via the
random.trust_bootloader command line option). But that's for the BSP
developer to ultimately decide.
So, if the board needs to have all that logic, why not also just have
it do the actual population of /chosen/rng-seed in ft_board_setup(),
which is not that many extra lines of code?
I considered that, but decided handling this logically belongs in
fdt_chosen(). Also, apart from saving the board code from the few
lines of boilerplate, doing it in ft_board_setup() is too late for at
least some use cases. For example, I want to allow the board logic to
decide
ok, let's pass back this buffer and use that as seed, but also let's
set random.trust_bootloader=n so no entropy is credited.
This requires the rng-seed handling to happen before bootargs
handling. For example, during the very first boot, the board might not
have a proper seed file, but the board could still return (a hash of)
some CPU serial# or whatnot, so that at least no two boards ever get
the same seed - the kernel always mixes in the value passed in
rng-seed, but if it is not "trusted", the kernel would still go
through the same motions as it would if no rng-seed was passed before
considering its CRNG initialized. I.e., by returning that
unique-to-this-board value and setting random.trust_bootloader=n, the
board would be no worse off than if board_rng_seed() returned nothing
at all.
