Subject: [PATCH v2 00/11] Introduce STM32 Firewall framework

Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x
platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers
register to the framework to offer firewall services such as access
granting.

This series of patches is a new approach on the previous STM32 system
bus, history is available here:
https://lore.kernel.org/lkml/20230127164040.1047583/

The need for such framework arises from the fact that there are now
multiple hardware firewalls implemented across multiple products.
Drivers are shared between different products, using the same code.
When it comes to firewalls, the purpose mostly stays the same: Protect
hardware resources. But the implementation differs, and there are
multiple types of firewalls: peripheral, memory, ...

Some hardware firewall controllers such as the RIFSC implemented on
STM32MP2x platforms may require to take ownership of a resource before
being able to use it, hence the requirement for firewall services to
take/release the ownership of such resources.

On the other hand, hardware firewall configurations are becoming
more and more complex. These mecanisms prevent platform crashes
or other firewall-related incoveniences by denying access to some
resources.

The stm32 firewall framework offers an API that is defined in
firewall controllers drivers to best fit the specificity of each
firewall.

For every peripherals protected by either the ETZPC or the RIFSC, the
firewall framework checks the firewall controlelr registers to see if
the peripheral's access is granted to the Linux kernel. If not, the
peripheral is configured as secure, the node is marked populated,
so that the driver is not probed for that device.

The firewall framework relies on the feature-domain-controller device
tree bindings: https://lore.kernel.org/lkml/0c0a82bb-18ae-d057-562b.
It is used by peripherals to reference a domain controller, in this
case a firewall feature domain. The bus uses the ID referenced by
the feature-domains property to know where to look in the firewall
to get the security configuration for the peripheral. This allows
a device tree description rather than a hardcoded peripheral table
in the bus driver.

The STM32 ETZPC device is responsible for filtering accesses based on
security level, or co-processor isolation for any resource connected
to it.

The RIFSC is responsible for filtering accesses based on Compartment
ID / security level / privilege level for any resource connected to
it.

STM32MP13/15/25 SoC device tree files are updated in this series to
implement this mecanism.

Changes in V2:

generic:
- Add fw_devlink dependency for "feature-domains"
property.

bindings:
- Corrected YAMLS errors highlighted by Rob's robot
- Firewall controllers YAMLs no longer define the
maxItems for the "feature-domains" property
- Renamed st,stm32-rifsc.yaml to
st,stm32mp25-rifsc.yaml
- Fix examples in YAML files
- Change feature-domains maxItems to 2 in firewall
consumer files as there should not be more than
2 entries for now
- Declare "feature-domain-names" as an optional
property for firewall controllers child nodes.
- Add missing "feature-domains" property declaration
in bosch,m_can.yaml and st,stm32-cryp.yaml files

firewall framework:
- Support multiple entries for "feature-domains"
property
- Better handle the device-tree parsing using
phandle+args APIs
- Remove "resource firewall" type
- Add a field for the name of the firewall entry
- Fix licenses

RIFSC:
- Add controller name
- Driver is now a module_platform_driver
- Fix license

ETZPC:
- Add controller name
- Driver is now a module_platform_driver
- Fix license

Device trees:
- Fix rifsc node name
- Move the "ranges" property under the
"feature-domains" one

Subject: [PATCH v2 04/11] dt-bindings: treewide: add feature-domains description

feature-domains is an optional property that allows a peripheral to
refer to one or more feature domain controller(s).

Description of this property is added to all peripheral binding files of
the peripheral under the STM32 firewall controllers. It allows an accurate
representation of the hardware, where various peripherals are connected
to this firewall bus. The firewall can then check the peripheral accesses
before allowing it to probe.

Changes in V2:
- Add missing "feature-domains" property declaration
in bosch,m_can.yaml and st,stm32-cryp.yaml files

Changes in V2:
- Corrected errors highlighted by Rob's robot
- No longer define the maxItems for the "feature-domains"
property
- Fix example (node name, status)
- Declare "feature-domain-names" as an optional
property for child nodes
- Fix description of "feature-domains" property
- Reorder the properties so it matches RIFSC
- Add missing "feature-domain-controller" property

+description: |
+ Resource isolation framework (RIF) is a comprehensive set of hardware blocks
+ designed to enforce and manage isolation of STM32 hardware resources like
+ memory and peripherals.
+
+ The RIFSC (RIF security controller) is composed of three sets of registers,
+ each managing a specific set of hardware resources:
+ - RISC registers associated with RISUP logic (resource isolation device unit
+ for peripherals), assign all non-RIF aware peripherals to zero, one or
+ any security domains (secure, privilege, compartment).
+ - RIMC registers: associated with RIMU logic (resource isolation master
+ unit), assign all non RIF-aware bus master to one security domain by
+ setting secure, privileged and compartment information on the system bus.
+ Alternatively, the RISUP logic controlling the device port access to a
+ peripheral can assign target bus attributes to this peripheral master port
+ (supported attribute: CID).
+ - RISC registers associated with RISAL logic (resource isolation device unit
+ for address space - Lite version), assign address space subregions to one
+ security domains (secure, privilege, compartment).

Subject: [PATCH v2 09/11] bus: etzpc: introduce ETZPC firewall controller driver

ETZPC is a peripheral and memory firewall controller that filter accesses
based on Arm TrustZone secure state and Arm CPU privilege execution level.
It handles MCU isolation as well.

Changes in V2:
- Add controller name
- Driver is now a module_platform_driver
- Use error code returned by stm32_firewall_populate_bus()
- Fix license

ETZPC is a firewall controller. Put all peripherals filtered by the
ETZPC as ETZPC subnodes and reference ETZPC as a
feature-domain-controller.

For more information on which peripheral is securable or supports MCU
isolation, please read the STM32MP15 reference manual.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/bus/st,stm32-etzpc.example.dtb: serial@4c001000: Unevaluated properties are not allowed ('feature-domains' was unexpected)
from schema $id: http://devicetree.org/schemas/serial/st,stm32-uart.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Subject: [PATCH v2 08/11] arm64: dts: st: add RIFSC as a domain controller for STM32MP25x boards

RIFSC is a firewall controller. Change its compatible so that is matches
the documentation and reference RIFSC as a feature-domain-controller.

Signed-off-by: Gatien Chevallier <[email protected]>

Changes in V2:
- Fix rifsc node name
- Move the "ranges" property under the
"feature-domains" one

Subject: [PATCH v2 07/11] bus: rifsc: introduce RIFSC firewall controller driver

RIFSC is a peripheral firewall controller that filter accesses based on
Arm TrustZone secure state, Arm CPU privilege execution level and
Compartment IDentification of the STM32 SoC subsystems.

Signed-off-by: Gatien Chevallier <[email protected]>

Changes in V2:
- Add controller name
- Driver is now a module_platform_driver
- Use error code returned by stm32_firewall_populate_bus()
- Fix license

Hi Simon,

This is indeed incorrect, set_bit is used to modify bit fields, not
writing to a register. I'll change to writel, as in
stm32_rif_release_semaphore(). Thank you for pointing this out.
