Tom Rini 73fd245623 Merge patch series "bootstd: Fix efi_mgr usage in bootmeths env var"
Sam Protsenko <semen.protsenko@linaro.org> says:

Defining the 'bootmeths' environment variable with efi_mgr causes NULL
pointer dereference when running 'bootflow scan' on the E850-96 board.
This patch series fixes that, and cleans up the surrounding code a

Sam ProtsenkoandTom Rini 8c61fc082e bootstd: Fix incorrect struct name in bootmeth_setup_iter_order()
There is no such thing as struct bootmeth, it's probably a typo. This
issue doesn't affect the execution as it's a pointer, and pointer sizes
are the same for all data types. But it can be confusing, so make it
struct udevice, as it should be.

Sam ProtsenkoandTom Rini 8da358c0a1 bootstd: Probe bootmeth devices for bootmeths env var
Specifying efi_mgr in 'bootmeths' environment variable leads to NULL
pointer dereference when 'bootflow scan' is executed, with call trace
like this:

    priv->fake_dev // NULL pointer dereference
    .read_bootflow = efi_mgr_read_bootflow()
    bootmeth_get_bootflow()
    bootflow_check()
    bootflow_scan_first()
    do_bootflow_scan()
    'bootflow scan -l'

That happens because in case when 'bootmeths' env var is defined the
bootmeth_efi_mgr driver is not probed, and the memory for its private
data isn't allocated by .priv_auto. In case when 'bootmeths' env var is
not defined, the std->bootmeth_count is 0, and the execution flow in
bootmeth_setup_iter_order() takes "no ordering" path, which in turn runs
uclass_get_device_by_seq() -> ... -> device_probe(), so issue isn't
present there. But when 'bootmeths' is defined and contains efi_mgr, the
std->bootmeth_count > 0, so bootmeth_setup_iter_order() follows the "we
have an ordering" path, where devices are not probed. In other words:

    'bootmeths' defined           'bootmeths' not defined
    --------------------------------------------------------
    priv == NULL                    priv != NULL

             bootmeth_setup_iter_order()
             bootflow_scan_first()
             do_bootflow_scan()

Add an explicit device_probe() call in "we have an ordering" case to fix
the issue.

Tom Rini ff43c2272a Merge patch series "Print version of the DM firmware"
Moteen Shah <m-shah@ti.com> says:

This patch series adds the functionality to print the DM firmware
version being used. Before requesting TISCI for the DM version we
first check if the DM split mode capability exists, if yes, we proceed
onto making the call to TISCI for retrieving the version information.

DM split mode capability indicates that the DM is a separate binary
altogether and has its own versioning information similar to TIFS.

Tom Rini 6226bfa41a Merge patch series "Add IPC support on MCU R5F cluster in Split Mode"
Beleswar Padhi <b-padhi@ti.com> says:

This series adds remoteproc support on MCU R5F in Split mode.

During boot, ROM can bring up the boot R5F cores in either lockstep or
split mode based on X509 certificate flags. If booted in lockstep mode,
the MCU R5F cores will run first the R5 SPL, and then once A72 comes up,
will run the Device Manager (DM) firmware. But if booted in split mode, core
0 will run DM firmware and second core sits in WFI. Shut it down so that
other firmwares can later be loaded on them.

The shutdown of MCU R5 Core 1 is invoked at A72 SPL init, as by that
time Device Manager (DM) is up and running on R5 Core 0. The shutdown
of MCU R5 Core 1 is handled by Device Manager itself.

Tom Rini 009d7722ff Merge patch series "bootstd: New bootmeth for RAUC A/B systems"
Martin Schwan <m.schwan@phytec.de> says:

This series implements a new bootmeth for RAUC A/B systems. RAUC (Robust
Auto Update Controller) is a lightweight update client, providing "Safe
and Secure OTA Updates for Embedded Linux". See the following links for
more information about RAUC:

  https://rauc.io/
  https://rauc.readthedocs.io/en/latest/

PHYTEC uses RAUC in its Yocto based distribution "Ampliphy" as the
default way of updating embedded devices based on PHYTEC hardware. So
far, the logic selecting the correct partitions and files to boot was
being implemented in the U-Boot environment. While this is a
straightforward way to do it, adding and supporting new platforms became
somewhat tedious and is platform-specific. The introduction of U-Boot's
"Standard Boot" provided a convincing alternative, promising a simpler
and more portable way of booting, even for RAUC systems. This led me to
implement a new bootmeth supporting RAUC A/B systems. Note, that this
new bootmeth is not proprietary to PHYTEC products and is designed to
work on other hardware with a RAUC A/B system, too.

The bootmeth currently only supports symmetric A/B partitioning layouts.
E.g. A/rescue is not (yet) supported. The partition indexes and default
slot tries can be specified via configuration options.

For now, the bootmeth_rauc uses a similar approach for loading the
Kernel and device tree as the bootmeth_script, in that it requires a FIT
containing a U-Boot script loading the desired distro. It could be
possible to support booting without a script and load the Kernel and DT
directly with this bootmeth, but I found the script method to be very
flexible for now, in letting the distro decide what to load.

The bootmeth_rauc was tested on a phyBOARD-Pollux i.MX8M Plus [1] with
BSP-Yocto-Ampliphy-i.MX8MP-PD24.1.2 [2].

Supported boot devices are currently only MMC devices, but it should be
possible to add SPI flashes in the future.

To test this patch stack with PHYTEC's phyBOARD-Pollux i.MX8M Plus
board, you need to adjust the boot files to include the boot.scr.uimg
containing the distro's boot script and set "optargs" to "${raucargs}"
in it. Also disable any legacyboot in the U-Boot environment and simply
boot with Standard Boot:

  bootmeth order rauc
  bootflow scan -lb

Moteen ShahandTom Rini 3bc174031d ti_sci_*: Add utility to access tisci firmware and SOC capability
Introduce response and request structs for receiving information
regarding FW/SOC capability from DM. The received capability can
further be used to call certain API's based on the feature supoorted
by the DM firmware.

Beleswar PadhiandTom Rini 87a9c1f5a0 arch: mach-k3: common: Add support to shutdown MCU R5 Core 1
During boot, ROM can bring up the MCU R5F cores in either lockstep or
split mode based on X509 certificate flags. If booted in split mode,
core 0 will run DM firmware and second core sits in WFI. Add support to
shut down core 1 so that other firmwares can later be loaded on them.

The shutdown of MCU R5 Core 1 is invoked at A72 SPL init, as by that
time Device Manager (DM) is up and running on R5 Core 0. The shutdown
request of Core 1 is handled by Device Manager itself.

Shmuel Leib MelamudandMarek Vasut b1d017afda renesas: Renesas R-Car Gen4 watchdog driver
Add support of Renesas R-Car Gen4 watchdog timer. Timeouts up to
8184.0s are supported (CKS1 register is not involved). The watchdog
uses the clock of type CLK_TYPE_GEN4_MDSEL.

The timeout is set in
dts/upstream/src/arm64/renesas/r8a779f0-spider-cpu.dtsi section &rwdt.

This driver is based on upstream linux commit:

Tom Rini ce2a7fcbd5 Merge patch series "list.h/treewide: get rid of no-op prefetch()"
Rasmus Villemoes <ravi@prevas.dk> says:

While looking through list.h, I saw that the regular list_* helpers
(and one of the hlist_* ones) still contain the prefetch() that was
removed in linux 14 years ago. It doesn't do anything, but makes the
macros harder to read, so get rid of it, and the fallback, no-op
definition that they relied on. That requires removing a few uses
outside list.h as well.

checkpatch warns about some whitespace issues in list.h, but as I've
copied whole kerneldoc+#define blocks directly from the linux kernel,
I think it's better to just accept that so that we don't introduce
needless diffs. The "macro argument reuse" arguments should also be
ignored, as e.g. the "member" arguments are obviously always just bare
identifiers, and the "pos" arguments must be assigned to multiple
times.

Rasmus VillemoesandTom Rini 1d19bbcb68 linux/list.h: drop fallback definition of prefetch()
None of the list helpers use prefetch() anymore, and no C code relies
on getting this definition from list.h. In any case, such an arch/cpu
specific thing does not belong in a header that just consists of cpp
helper macros.
