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.

Yann Gautier 1d204ee4ab feat(plat/st): use FIP to load images
BL2 still uses the STM32 header binary format to be loaded from ROM code.
BL32 and BL33 and their respective device tree files are now put together
in a FIP file.
One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are
in charge of removing useless nodes for a given BL. This is done because
BL2 and BL32 share the same device tree files base.

The previous way of booting is still available, the compilation flag
STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files
are duplicated and their names modified with _stm32_ to avoid too much
switches in the code.

Andre Przywara c3ce73be0b fix(plat/arm_fpga): increase initrd size
In the comment in the ARM FPGA DT we promise a generous 100 MB initrd,
but actually describe only a size of 20 MB.

As initrds are the most common and easy userland option for the boards,
let's increase the maximum size to the advertised 100 MB, to avoid
unpacking errors when an initrd exceeds the current limit of 20 MB.

Grzegorz Szymaszek c3c6732f8e fdts: stm32mp1: add support for the Seeed Odyssey SoM and board
Seeed Studio’s SoM‐STM32MP157C is a System‐on‐Module that integrates the
STM32MP157C MPU (the 650 MHz dual‐core variant with a GPU and a
cryptographic processor) the STPMIC1A PMIC, 512 MB of DDR3 RAM and a
4 GB eMMC. There are two LEDs as well, one hardwired to the PMIC’s VDD
output, and the other available at the MPU’s port PG3. The SoM can be
plugged into a carrier board using its three 70‑pin connectors.

Seeed Odyssey‐STM32MP157C is the reference carrier board for the SoM in
a Raspberry Pi‐like form factor. It features a WiFi/Bluetooth chip, a
microSD card port and various I/O interfaces.

The device tree is based on the DKx boards. TF‑A was successfully tested
on the board with Buildroot 2021.02 and U-Boot 2021.04.

see:

Arm Cortex-A76 Core:
"Each timer provides an active-LOW interrupt output to the SoC."

"It generates timer events as active-LOW interrupt outputs and
event streams."

IRQ_TYPE_EDGE_RISING = 0x01:

interrupts = <1 13 0xff01>,
             <1 14 0xff01>,
             <1 11 0xff01>,

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.

Mikael Olsson 5d5fb10f9c plat/arm/juno: Add support to use hw_config in BL31
To make it possible to use the hw_config device tree for dynamic
configuration in BL31 on the Arm Juno platform. A placeholder hw_config
has been added that is included in the FIP and a Juno specific BL31
setup has been added to populate fconf with the hw_config.

Juno's BL2 setup has been updated to align it with the new behavior
implemented in the Arm FVP platform, where fw_config is passed in arg1
to BL31 instead of soc_fw_config. The BL31 setup is expected to use the
fw_config passed in arg1 to find the hw_config.

This is deemed ok for now, but for use in the field, the SiP will likely

Andre Przywara b48883c79a arm_fpga: Add devicetree file
The FPGA images used in Arm Ltd. focus on CPU cores, so they share a
common platform, with a minimal set of peripherals (interconnect, GIC,
UART).
This allows to support most platforms with a single devicetree file.
The topology and number of CPU cores differ, but those will added at
runtime, in BL31. Other adjustments (GICR size, SPE node, command line)
are also done at this point.

Add the common devicetree file to TF-A's build system, so it can be
build together with BL31. At runtime, the resulting .dtb file should be
uploaded to the address given with FPGA_PRELOADED_DTB_BASE at build time.

Yann Gautier 277d6af561 fdts: stm32mp1: realign device tree with kernel
There is one dtsi file per SoC version:
- STM32MP151: common part for all version, Single Cortex-A7
- STM32MP153: Dual Cortex-A7
- STM32MP157: + GPU and DSI, but not needed for TF-A

The STM32MP15xC include a cryptography peripheral, add it in a dedicated
file.

There are 4 packages available, for which  the IOs number change. Have one
file for each package. The 2 packages AB and AD are added.

STM32157A-DK1 and STM32MP157C-DK2 share most of their features, a common
dkx file is then created.

Some reordering is done in other files, and realign with kernel DT files.

The DDR files are generated with our internal tool, no changes in the
registers values.
