This patch provides separation of GICD, GICR accessor functions and adds new macros for GICv3 registers access as a preparation for GICv3.1 and GICv4 support. NOTE: Platforms need to modify to include both 'gicdv3_helpers.c' and 'gicrv3_helpers.c' instead of the single helper file previously.

On systems that have multiple platform components that can interpret the SCMI messages, there is a need to support multiple SCMI channels (one each to those platform components). Extend the existing SCMI interface that currently supports only a single SCMI channel to support multiple SCMI channels.

NOTE for platform integrators: API `plat_psci_stat_get_residency()` third argument `last_cpu_idx` is changed from "signed int" to the "unsigned int" type. Issue / Trouble points 1. cpu_idx is used as mix of `unsigned int` and `signed int` in code with typecasting at some places leading to coverity issues. 2. Underlying platform API's return cpu_idx as `unsigned int` and comparison is performed with platform specific defines `PLAFORM_xxx` which is not consistent Misra Rule 10.4: The value of a complex expression of integer type may only be cast to a type that is narrower and of the same signedness as the underlying type of the expression. Based on above points, cpu_idx is kept as `unsigned int` to match the API's and low-level functions and platform defines are updated where ever required Signed-off-by: Deepika Bhavnani <deepika.bhavnani@arm.com> Change-Id: Ib26fd16e420c35527204b126b9b91e8babcc3a5c

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.

The BL1 stage setup code for ARM platforms sets up the SP805 watchdog controller as the secure watchdog. But not all ARM platforms use SP805 as the secure watchdog controller. So introduce two new ARM platform code specific wrapper functions to start and stop the secure watchdog. These functions then replace the calls to SP805 driver in common BL1 setup code. All the ARM platforms implement these wrapper functions by either calling into SP805 driver or the SBSA watchdog driver.

This file is used when building the cert_create tool without using the 'standard' set of Arm OID values as defined in the TBBR specification (see tbbr_oid.h). This configuration is enabled by setting USE_TBBR_DEFS to 0 during build. At the moment this will fail because the header file included by this file was removed in commit bb41eb7a ("cert: move platform_oid.h to include/tools_share for all platforms"). For the SGM platform this means that there is no current use for this file. Change-Id: I3c82983ada62330f1ab6be6d6c0cf489adabae7b Signed-off-by: Paul Beesley <paul.beesley@arm.com>

From now on, platform_def.h must include any header with definitions that are platform-specific (like arm_def.h) and the included headers mustn't include back platform_def.h, and shouldn't be used by other files. Only platform_def.h should be included in other files. This will ensure that all needed definitions are present, rather than needing to include all the headers in all the definitions' headers just in case. This also prevents problems like cyclic dependencies. Change-Id: I9d3cf4d1de4b956fa035c79545222697acdaf5ca Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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.

In order to allow Arm platforms to override the default list of PSCI callbacks, remove the existing weak implementation of 'plat_arm_psci_override_pm_ops' function and let all the Arm platforms implement their own 'plat_arm_psci_override_pm_ops' function. For platforms that support SCMI protocol, the function 'css_scmi_override_pm_ops' can be additionally used as well to override the default PSCI callbacks.

The CSS_SYSTEM_PWR_DMN_LVL macro that defines the system power domain level is fixed at ARM_PWR_LVL2 for all CSS platforms. However, the system power domain level can be different for CSS platforms that use multi-threaded CPUs. So, in preparation towards adding support for platforms that use multi-threaded CPUs, refactor the definition of CSS_SYSTEM_PWR_DMN_LVL such that CSS_SYSTEM_PWR_DMN_LVL is uniquely defined for each of the CSS platform.

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>

The default values of 'plat_css_scmi_plat_info' is not applicable for all the platforms. There should be a provision to let platform code to register a platform specific instance of scmi_channel_plat_info_t. Add a new API 'plat_css_get_scmi_info' which lets the platform to register a platform specific instance of scmi_channel_plat_info_t and remove the default values. In addition to this, the existing 'plat_css_scmi_plat_info' structure is removed from the common code and instantiated for the platforms that need it. This allows for a consistent provisioning of the SCMI channel information across all the existing and upcoming platforms.

This file is shared between FVP and all CSS platforms. While it may be true that some definitions can be common, it doesn't make sense conceptually. For example, the stack size depends on the platform and so does the SRAM size. After removing them, there are not enough common definitions to justify having this header, so the other definitions have been moved to the platform_def.h of FVP, board_css_def.h and arm_def.h.

In the function, bl1_early_platform_setup in the file plat/arm/css/sgm/sgm_bl1_setup.c: plat_config_init(); arm_bl1_early_platform_setup(); The debug messages logged by plat_config_init() are lost because the console is initialized in the function arm_bl1_early_platform_setup() To see the logs of plat_config_init, this fix re-orders above calls so that the console is initialized before call to plat_config_init.

This option makes it hard to optimize the memory definitions of all Arm platforms because any change in the common defines must work in all of them. The best thing to do is to remove it and move the definition to each platform's header. FVP, SGI and SGM were using the definitions in board_arm_def.h. The definitions have been copied to each platform's platform_def.h. Juno was already using the ones in platform_def.h, so there have been no changes.
