      fix(plat/arm_fpga): increase initrd size · c3ce73be
      Andre Przywara authored 
      

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.

      fdts: stm32mp1: add support for the Seeed Odyssey SoM and board · c3c6732f
      Grzegorz Szymaszek authored 
      

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.

The new pins—PA8, PA9, PE5, and PC7—are described in a new pinctrl node
named “sdmmc2-d47-3”, AKA phandle “sdmmc2_d47_pins_d”. These names are
identical to their Linux kernel counterparts (commit

      fdts: stm32mp1: add I2C2 pins in the pinctrl · 214b4f9a
      Grzegorz Szymaszek authored 
      

Some STM32MP1‐based boards, like Seeed Studio’s SoM‐STM32MP157C, have
the SoC connected to the PMIC via I2C2 instead of I2C4 (which is used on
the official ST development boards). This commit brings TF‑A one step
closer to boot on such boards.

The pins used, PH4 and PH5, are described in a new pinctrl node named
“i2c2-0”, AKA phandle “i2c2_pins_a”. These names are identical to their
Linux kernel counterparts (commit
7af08140979a6e7e12b78c93b8625c8d25b084e2).

      Plat FVP: Fix Generic Timer interrupt types · dfa6c540
      Alexei Fedorov authored 
      

The Arm Generic Timer specification mandates that the
interrupt associated with each timer is low level triggered,
see:

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

Arm Cortex-A53 MPCore Processor:
"It generates timer events as active-LOW interrupt outputs and
event streams."

The following files in fdts\

fvp-base-gicv3-psci-common.dtsi
fvp-base-gicv3-psci-aarch32-common.dtsi
fvp-base-gicv2-psci-aarch32.dts
fvp-base-gicv2-psci.dts
fvp-foundation-gicv2-psci.dts
fvp-foundation-gicv3-psci.dts

describe interrupt types as edge rising
IRQ_TYPE_EDGE_RISING = 0x01:

interrupts = <1 13 0xff01>,
             <1 14 0xff01>,
             <1 11 0xff01>,
             <1 10 0xff01>;

, see include\dt-bindings\interrupt-controller\arm-gic.h:

which causes Linux to generate the warnings below:
arch_timer: WARNING: Invalid trigger for IRQ5, assuming level low
arch_timer: WARNING: Please fix your firmware

This patch adds GIC_CPU_MASK_RAW macro definition to
include\dt-bindings\interrupt-controller\arm-gic.h,
modifies interrupt type to IRQ_TYPE_LEVEL_LOW and
makes use of type definitions in arm-gic.h.

      Add SiP service to configure Arm Ethos-N NPU · 76a21174
      Mikael Olsson authored 
      

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.

      plat/arm/juno: Add support to use hw_config in BL31 · 5d5fb10f
      Mikael Olsson authored 
      

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.

      fdts: stm32mp1: add support for Linux Automation MC-1 board · 2fbb6064
      Ahmad Fatoum authored 
      

The Linux Automation MC-1 is a SBC built around the Octavo Systems
OSD32MP15x SiP. The SiP features up to 1 GB DDR3 RAM, EEPROM and
PMIC. The board has eMMC and a SD slot for storage.

The SDRAM calibration values are taken as is from the DKx boards, which
seem to be suitable for operation at German room temperature.

This is deemed ok for now, but for use in the field, the SiP will likely
need to have its timings determined in a climate chamber.

      arm_fpga: Add devicetree file · b48883c7
      Andre Przywara authored 
      

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.

      fdts: stm32mp1: realign device tree with kernel · 277d6af5
      Yann Gautier authored 
      

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.

      tbbr/dualroot: rename SP package certificate file · 03a5225c
      Manish Pandey authored 
      

Currently only single signing domain is supported for SP packages but
there is plan to support dual signing domains if CoT is dualroot.

SP_CONTENT_CERT_ID is the certificate file which is currently generated
and signed with trusted world key which in-turn is derived from Silicon
provider RoT key.
To allow dual signing domain for SP packages, other certificate file
will be derived from Platform owned RoT key.

This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and
does other related changes.
