The Jaguar SBC provides an M.2 slot connected to the pcie3 controller.
In contrast to a number of other boards the pcie-refclk is gpio-controlled,
so the necessary clock and is added to the list of pcie3 clocks.

Marek Mojík <marek.mojik@nic.cz> says:
Hello all,
this is a continuation of previous work by Pali to add support for the
Turris 1.x board. As the patches were based on u-boot v2022.04, a
nontrivial rebasing was needed.
Some notes:
- Some options that are in SD defconfig are disabled in NOR defconfig
because over the years u-boot grew and the old NOR defconfig will not
fit into NOR memory.
- SD boot with RAM larger than 2GB will only allocate 2GB of RAM (We
were not able to fix this yet)
|
|
When U-Boot is running from flash memory (execute in place) then
gd->fdt_blob before relocation points to read-only flash memory.
So U-Boot calls board_fix_fdt() with read-only gd->fdt_blob pointer which
cause immediate CPU crash when callback is trying to modify gd->fdt_blob.
Fix this issue by introducing a new config option OF_INITIAL_DTB_READONLY
which moves fix_fdt callback after the reloc_fdt callback. This makes
CONFIG_OF_BOARD_FIXUP working also if U-Boot before relocation is not
running from read/write (S)RAM memory.
This is required for mpc85xx boards when booting from flash NOR.

Hi all,
This series enabled qemu-xtensa board.
For dc232b CPU it needs to be built with toolchain[1].
This is a side product of me investigating architectures
physical address != virtual address in U-Boot. Now we can
get it covered under CI and regular tests.
VirtIO devices are not working as expected, due to U-Boot's
assumption on VA == PA everywhere, I'm going to get this fixed
later.
My Xtensa knowledge is pretty limited, Xtensa people please
feel free to point out if I got anything wrong.
Thanks

Apart from the host-only usb3 controller (host2) the rk3588 also provides
two dual-role controllers. On the Tiger-Haikou combination these are
connected to the lower usb3-host port in host-only mode and the micro-usb3
port for dual-role operation.
Add the necessary controllers, phys to the Tiger-Haikou board and enable
the usb-id extcon.

The Q7 standard specifies a usb-id pin on the connector to distiuish
between host and device mode. Model this via the usb-id extcon binding.
While the pin is part of the Q7 standard, so part of the module, the
extcon stays disabled in the som dtsi and will only be enabled in a
baseboard using it.

The mmu600_pcie is connected with the five PCIe controllers.
The mmu600_php is connected with the USB3 controller, the GMAC
controllers, and the SATA controllers.
See 8.2 Block Diagram, in rk3588 TRM (Technical Reference Manual).
The IOMMUs are disabled by default, as further patches are needed to
program the SID/SSIDs in to the IOMMUs.
iommu: Default domain type: Translated
iommu: DMA domain TLB invalidation policy: strict mode
arm-smmu-v3 fc900000.iommu: ias 48-bit, oas 48-bit (features 0x001c1eaf)
arm-smmu-v3 fc900000.iommu: allocated 65536 entries for cmdq
arm-smmu-v3 fc900000.iommu: allocated 32768 entries for evtq
arm-smmu-v3 fc900000.iommu: msi_domain absent - falling back to wired irqs
Additionally, the IOMMU correctly triggers an IOMMU fault when
a PCIe device performs a write (since the device hasn't been
assigned a SID/SSID):
arm-smmu-v3 fc900000.iommu: event 0x02 received:
arm-smmu-v3 fc900000.iommu: 0x0000010000000002

arm-smmu-v3 fc900000.iommu: 0x0000000000000000
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
While this doesn't provide much value as is, having the devices as
disabled in the device tree will allow developers to see that the rk3588
actually has IOMMUs on the SoC.

This adds the build infrastructure for checking DT binding schema
documents and validating dtb files using the binding schema. Here we use
devicetree-rebasing subtree to provide the DT bindings. Along with that
adapt dts/upstream/Bindings/Makefile to align with old U-Boot Kbuild
infrastructure.
Dependency:
-----------
The DT schema project must be installed in order to validate the DT schema
binding documents and validate DTS files using the DT schema. The DT schema
project can be installed with pip::
pip3 install dtschema
Note that 'dtschema' installation requires 'swig' and Python development
files installed first. On Debian/Ubuntu systems::
apt install swig python3-dev
Testing:
--------
Build dts files and check using DT binding schema:
$ make dtbs_check
Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.
Note, at this point dtbs_check is an optional build target as there are
many warnings generated due to custom DT properties used by many
platforms in u-boot. It is expected with these checks that compliance
with DT bindings to take place. Once that's done it can be added to CI
builds to remain compliant with DT bindings.

Sandbox unit tests in U-Boot proper load a test device tree to have some
devices to work with. In order to do the same in SPL, we must enable
SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When
generating platdata from a devicetree, it is expected that we will not need
devicetree access functions (even though SPL_OF_CONTROL is enabled). This
expectation does not hold for sandbox, so allow user control of
SPL_OF_REAL.
There are several places in the tree where conditions involving OF_PLATDATA
or OF_REAL no longer function correctly when both of these options can be
selected at the same time. Adjust these conditions accordingly.

When building for a custom board, it is quite common to maintain a
private branch which include some defconfig and .dts files. But to
hook up those .dts files requires modifying a file "belonging" to
upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
to a newer upstream then often results in a conflict which, while it
is trivial to resolve by hand, makes it harder to have a CI do "try to
build our board against latest upstream".
The .config usually includes information on precisely what .dtb(s) are
needed, so to avoid having to modify the Makefile, simply add the
files in (SPL_)OF_LIST to dtb-y.
A technicality is that (SPL_)OF_LIST is not always defined, so rework
the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
(SPL_)OF_CONTROL), but only prompted for in the cases which used to be
their "depends on".
nios2 and microblaze already have something like this in their
dts/Makefile, and the rationale in commit 41f59f68539 is similar to
the above. So this simply generalizes existing practice. Followup
patches could remove the logic in those two makefiles, just as there's
potential for moving some common boilerplate from all the
arch/*/dts/Makefile files to the new scripts/Makefile.dts.

The build system already automatically looks for and includes an
in-tree *-u-boot.dtsi when building the control .dtb. However, there
are some things that are awkward to maintain in such an in-tree file,
most notably the metadata associated to public keys used for verified
boot.
The only "official" API to get that metadata into the .dtb is via
mkimage, as a side effect of building an actual signed image. But
there are multiple problems with that. First of all, the final U-Boot
(be it U-Boot proper or an SPL) image is built based on a binary
image, the .dtb, and possibly some other binary artifacts. So
modifying the .dtb after the build requires the meta-buildsystem
(Yocto, buildroot, whatnot) to know about and repeat some of the steps
that are already known to and handled by U-Boot's build system,
resulting in needless duplication of code. It's also somewhat annoying
and inconsistent to have a .dtb file in the build folder which is not
generated by the command listed in the corresponding .cmd file (that
of course applies to any generated file).
So the contents of the /signature node really needs to be baked into
the .dtb file when it is first created, which means providing the
relevant data in the form of a .dtsi file. One could in theory put
that data into the *-u-boot.dtsi file, but it's more convenient to be
able to provide it externally: For example, when developing for a
customer, it's common to use a set of dummy keys for development,
while the consultants do not (and should not) have access to the
actual keys used in production. For such a setup, it's easier if the
keys used are chosen via the meta-buildsystem and the path(s) patched
in during the configure step. And of course, nothing prevents anybody
from having DEVICE_TREE_INCLUDES point at files maintained in git, or
for that matter from including the public key metadata in the
*-u-boot.dtsi directly and ignore this feature.
There are other uses for this, e.g. in combination with ENV_IMPORT_FDT
it can be used for providing the contents of the /config/environment
node, so I don't want to tie this exclusively to use for verified
boot.

U-Boot always needs some sort of a device tree in the build. Some boards
never actually use this, at least in production systems, since a prior
firmware stage sets one up and passes it to U-Boot. At present the only
mechanism to do that is with custom function (OF_BOARD), but future work
will include a standard way of doing this ('standard passage').
It can be confusing to see a device tree emitted from the U-Boot build in
this situation. Add an option to drop it.

When U-Boot is started from another firmware program, not just a prior
phase of U-Boot, special behaviour is typically used. In particular, the
device tree may come from that prior stage.
At present this is sort-of indicated by OF_BOARD, although the
correlation is not 1:1, since that option simply means that the board has
a custom mechanism for obtaining the device tree. For example, sandbox
defines OF_BOARD. Also the board_fdt_blob_setup() function can in fact
make use of the devicetree in U-Boot if it wishes, as used by
dragonboard410c until very recently.
Add an explicit Kconfig for this situation. Update the OF_BOARD option to
more-accurately reflect what it is doing, e.g. for sandbox.
Drop the docs in the README as it is out of date.

This was added as a hack to work around not having an in-tree devicetree.
Now that this is fixed it is not needed.
Drop it.

This should not be a separate option from OF_SEPARATE. It is a run-time
option to override the devicetree, even if present.
Move the option out of the choice.
Disable BINMAN_FDT for a few boards which don't actually use it.

OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined, even
when DTC is provided. The built dtc is not actually used, so this is a
waste of time.
Update the Makefile logic to build dtc only if one is not provided to the
build with the DTC variable. Add documentation to explain this.
This saves about 3.5 seconds of elapsed time on a clean build of
sandbox_spl for me.
