Instead of using defines for the RAM size and base address, retrieve these
information from the devicetree.
This aligns with the sama5d27_som1_ek board in commit 73c1589f025d9

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.

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.

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

this configuration option. The early SPL stack is however pointing

System RAM instead, where it cannot interfere with the payload loaded

Rasmus Villemoes <[email protected]> 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.
Link: https://lore.kernel.org/r/[email protected]

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.

AFAICT, CONFIG_CPU_HAS_PREFETCH has never existed as a proper Kconfig

Signed-off-by: Rasmus Villemoes <[email protected]>
|

These all end up using the no-op prefetch() defined in linux/list.h,
because the only possible real implementation is in
arch/mips/include/asm/processor.h, which is behing
CONFIG_CPU_HAS_PREFETCH which is nowhere defined.
In order to be able to drop that fallback definition from list.h,
first remove all uses.

The use of prefetch() in these list helpers was dropped back in 2011
in linux (e66eed651fd1 ("list: remove prefetching from regular list
iterators")). No arch in U-Boot defines any actual prefetch(), and as
the referenced commit says, it's usually not a win anyway.
Whole-sale sync of list.h is not really feasible, but we can
synchronize the macros containing a prefetch() with their linux
implementations as of v6.15-rc5, also importing the various helpers
needed, e.g. list_is_head() and list_next_entry().

Contrary to the datasheet, setting both DETACH and PULLD_DIS bits to 1
does not always drive the DP and DM lines to high-impedance. This
prevents the host from reliably detecting a USB disconnect and subsequent
reconnect.
The symptom is that the first gadget command (e.g., dhcp) succeeds, while
subsequent commands (e.g., nfs) fail.
Disabling and re-enabling the controller entirely, instead of toggling the
PULLD_DIS bit, reliably generates a disconnect event.
The Linux driver works correctly because gadget_disconnect/gadget_connect
are always followed by gadget_udc_start/gadget_udc_stop. In U-Boot
pullup() is used solely.
This behavior has been observed on the SAM9X60-Curiosity and
AT91SAM9G25-EK boards and has been reported to Microchip.
