This change introduces drivers to allow a platform to create a basic SCMI service and register handlers for client request (SCMI agent) on system resources. This is the first piece of the drivers: an entry function, the SCMI base protocol support and helpers for create the response message. With this change, scmi_process_message() is the entry function to process an incoming SCMI message. The function expect the message is already copied from shared memory into secure memory. The message structure stores message reference and output buffer reference where response message shall be stored. scmi_process_message() calls the SCMI protocol driver according to the protocol ID in the message. The SCMI protocol driver will call defined platform handlers according to the message content. This change introduces only the SCMI base protocol as defined in SCMI specification v2.0 [1]. Not all the messages defined in the specification are supported. The SCMI message implementation is derived from the OP-TEE project [2] itself based on the SCP-firmware implementation [3] of the SCMI protocol server side.

ETZPC stands for Extended TrustZone Protection Controller. It is a resource conditional access device. It is mainly based on Arm TZPC. ST ETZPC exposes memory mapped DECPROT cells to set access permissions to SoC peripheral interfaces as I2C, SPI, DDR controllers, and some of the SoC internal memories. ST ETZPC exposes memory mapped TZMA cells to set access permissions to some SoC internal memories.

Changes stm32mp1 reset driver to API to add a timeout argument to stm32mp_reset_assert() and stm32mp_reset_deassert() and a return value. With a supplied timeout, the functions wait the target reset state is reached before returning. With a timeout of zero, the functions simply load target reset state in SoC interface and return without waiting. Helper functions stm32mp_reset_set() and stm32mp_reset_release() use a zero timeout and return without a return code. This change updates few stm32 drivers and plat/stm32mp1 blé_plat_setup.c accordingly without any functional change. functional change.

Oscillators, PLLs and some system clocks can be related straight to a parent clock. Prior this change were only oscillators and few clocks supported by this look up. This changes adds PLLs and other system clocks. This enables for flexible use of clock tree exploration when computing a clock frequency value.

The device tree parsing code for the STM32 platform is using its own FDT helper functions, some of them being rather generic. In particular the existing fdt_read_uint32_array() implementation is now almost identical to the new generic code in fdt_wrappers.c, so we can remove the ST specific version and adjust the existing callers. Compared to the original ST implementation the new version takes a pointer to the DTB as the first argument, and also swaps the order of the number of cells and the pointer.

Introduce driver for STM32 IWDG peripheral (Independent Watchdog). It is configured according to device tree content and should be enabled from there. The watchdog is not started by default. It can be started after an HW reset if the dedicated OTP is fused. The watchdog also needs to be frozen if a debugger is attached. This is done by configuring the correct bits in DBGMCU. This configuration is allowed by checking BSEC properties. An increase of BL2 size is also required when adding this new code.

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__. All common C compilers predefine a macro called __ASSEMBLER__ when preprocessing a .S file. There is no reason for TF-A to define it's own __ASSEMBLY__ macro for this purpose instead. To unify code with the export headers (which use __ASSEMBLER__ to avoid one extra dependency), let's deprecate __ASSEMBLY__ and switch the code base over to the predefined standard.

Rework the macro that eases the table definition: the src and msk fields are now using MASK and SHIFT defines of each source register. Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to _UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields. Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7 to reflect the size of the register field, even if there are only 3 possible clock sources. The mask value is also corrected for QSPI and FMC clock selection.

Regulator configuration at boot takes more information from DT. I2C configuration from DT is done in I2C driver. I2C driver manages more transfer modes. The min voltage of buck1 should also be increased to 1.2V, else the platform does not boot. Heavily modifies stm32_i2c.c since many functions move inside the source file to remove redundant declarations.

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca339 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
