arm: armada: dts: Add clock to armada-ap80x uart1

The uart1 node was missing the 'clock-frequency' property. This meant
the driver for this device would fail at probe.
The clock for uart1 is fed from the same source as uart0 and is a fixed
200MHz clock. This is confirmed via documentation for the CN9130 SoC

highbank: scan into hb_sregs DT subnodes

The DT used for Calxeda Highbank and Midway systems exposes a "system
registers" block, modeled as a DT subnode.
This includes several clocks, including the two fixed clocks for the
main oscillator and timer.

So far U-Boot was ignorant of this special construct (a "clocks" node
within the "hb-sregs" node), as it didn't need the PLL clocks in there.
But that also meant we lost the fixed clocks, which form the base for
the UART baudrate generator and also the SP804 timer.

To allow the generic PL011 and SP804 driver to read the clock rate,
add a simple bus driver, which triggers the DT node discovery inside this

Make it explicit what we want: the "addr" argument needs to go into r1,
so we add another register variable. This allows to drop the "noinline"

Rasmus Villemoes [Fri, 28 Oct 2022 11:50:54 +0000 (13:50 +0200)]
cyclic: get rid of cyclic_init()

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.

cyclic: switch to using hlist instead of list

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.

Merge branch '2022-10-31-FWU-add-FWU-multi-bank-update-feature-support'

To quote the author:
The patchset adds support for the FWU Multi Bank Update[1]
feature. Certain aspects of the Dependable Boot[2] specification have
also been implemented.

The FWU multi bank update feature is used for supporting multiple
sets(also called banks) of firmware image(s), allowing the platform to
boot from a different bank, in case it fails to boot from the active
bank. This functionality is supported by keeping the relevant
information in a structure called metadata, which provides information
on the images. Among other parameters, the metadata structure contains
information on the currect active bank that is being used to boot
image(s).

Functionality is being added to work with the UEFI capsule driver in
u-boot. The metadata is read to gather information on the update bank,
which is the bank to which the firmware images would be flashed to. On
a successful completion of the update of all components, the active
bank field in the metadata is updated, to reflect the bank from which
the platform will boot on the subsequent boots.

Currently, the feature is being enabled on the STM32MP157C-DK2 and
Synquacer boards. The DK2 board boots a FIP image from a uSD card
partitioned with the GPT partioning scheme, while the Synquacer board
boots a FIP image from a MTD partitioned SPI NOR flash device.

This feature also requires changes in a previous stage of
bootloader, which parses the metadata and selects the bank to boot the
image(s) from. Support has being added in tf-a(BL2 stage) for the
STM32MP157C-DK2 board to boot the active bank images. These changes
have been merged to the upstream tf-a repository.

The patch for adding a python test for the feature has been developed,
and was sent in the version 5 of the patches[3]. However, the test
script depends on adding support for the feature on MTD SPI NOR
devices, and that is being done as part of the Synquacer
patches. Hence these set of patches do not have the test script for
the feature. That will be added through the patches for adding support
for the feauture on Synquacer platform.

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.

events that need to be run after the platform has been initialised and

FWU: STM32MP1: Add support to read boot index from backup register

The FWU Multi Bank Update feature allows the platform to boot the
firmware images from one of the partitions(banks). The first stage
bootloader(fsbl) passes the value of the boot index, i.e. the bank
from which the firmware images were booted from to U-Boot. On the
STM32MP157C-DK2 board, this value is passed through one of the SoC's
backup register. Add a function to read the boot index value from the
backup register.
