Laurent Carlier	1c65989e70	feat(drivers/arm/ethosn)!: multi-device support Add support for Arm Ethos-N NPU multi-device. The device tree parsing currently only supports one NPU device with multiple cores. To be able to support multi-device NPU configurations this patch adds support for having multiple NPU devices in the device tree. To be able to support multiple NPU devices in the SMC API, it has been changed in an incompatible way so the API version has been bumped.

Mikael Olsson	76a21174d2	Add SiP service to configure Arm Ethos-N NPU By default the Arm Ethos-N NPU will boot up in secure mode. In this mode the non-secure world cannot access the registers needed to use the NPU. To still allow the non-secure world to use the NPU, a SiP service has been added that can delegate non-secure access to the registers needed to use it. Only the HW_CONFIG for the Arm Juno platform has been updated to include the device tree for the NPU and the platform currently only loads the HW_CONFIG in AArch64 builds.

feat(drivers/arm/ethosn)!: multi-device support

Add support for Arm Ethos-N NPU multi-device.

The device tree parsing currently only supports one NPU device with
multiple cores. To be able to support multi-device NPU configurations
this patch adds support for having multiple NPU devices in the device
tree.

To be able to support multiple NPU devices in the SMC API, it has been
changed in an incompatible way so the API version has been bumped.

Add SiP service to configure Arm Ethos-N NPU

By default the Arm Ethos-N NPU will boot up in secure mode. In this mode
the non-secure world cannot access the registers needed to use the NPU.
To still allow the non-secure world to use the NPU, a SiP service has
been added that can delegate non-secure access to the registers needed
to use it.

Only the HW_CONFIG for the Arm Juno platform has been updated to include
the device tree for the NPU and the platform currently only loads the
HW_CONFIG in AArch64 builds.
