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>

This patch introduces new helper routines that allow configuring the individual IRQs to be edge/level-triggered via GICD_ICFGR registers. This is helpful to modify the default configuration of the non-secure GIC SPI's, which are all set during initialization to be level-sensitive.

The codebase was using non-standard headers. It is needed to replace them by the correct ones so that we can use the new libc headers. Change-Id: I530f71d9510cb036e69fe79823c8230afe890b9d Acked-by: Sumit Garg <sumit.garg@linaro.org> Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

Emit runtime warnings when intializing the GIC drivers using the deprecated method of defining integer interrupt arrays in the GIC driver data structures; interrupt_prop_t arrays should be used instead. This helps platforms detect that they have migration work to do. Previously, no warning was emitted in this case. This affects both the GICv2 and GICv3 drivers. Also use the __deprecated attribute to emit a build time warning if these deprecated fields are used. These warnings are suppressed in the GIC driver compatibility functions but will be visible if platforms use them.

The GIC driver initialization currently allows an array of interrupts to be configured as secure. Future use cases would require more interrupt configuration other than just security, such as priority. This patch introduces a new interrupt property array as part of both GICv2 and GICv3 driver data. The platform can populate the array with interrupt numbers and respective properties. The corresponding driver initialization iterates through the array, and applies interrupt configuration as required. This capability, and the current way of supplying array (or arrays, in case of GICv3) of secure interrupts, are however mutually exclusive. Henceforth, the platform should supply either: - A list of interrupts to be mapped as secure (the current way). Platforms that do this will continue working as they were. With this patch, this scheme is deprecated. - A list of interrupt properties (properties include interrupt group). Individual interrupt properties are specified via. descriptors of type 'interrupt_prop_desc_t', which can be populated with the macro INTR_PROP_DESC(). A run time assert checks that the platform doesn't specify both. Henceforth the old scheme of providing list of secure interrupts is deprecated. When built with ERROR_DEPRECATED=1, GIC drivers will require that the interrupt properties are supplied instead of an array of secure interrupts. Add a section to firmware design about configuring secure interrupts.

The back end GIC driver converts and assigns the interrupt type to suitable group. For GICv2, a build option GICV2_G0_FOR_EL3 is introduced, which determines to which type Group 0 interrupts maps to. - When the build option is set 0 (the default), Group 0 interrupts are meant for Secure EL1. This is presently the case. - Otherwise, Group 0 interrupts are meant for EL3. This means the SPD will have to synchronously hand over the interrupt to Secure EL1. The query API allows the platform to query whether the platform supports interrupts of a given type. API documentation updated.

The PE target mask is used to translate linear PE index (returned by platform core position) to a bit mask used when targeting interrupts to a PE, viz. when raising SGIs and routing SPIs. The platform shall: - Populate the driver data with a pointer to array that's to contain per-PE target masks. - Invoke the new driver API 'gicv2_set_pe_target_mask()' during per-CPU initialization so that the driver populates the target mask for that CPU. Platforms that don't intend to target interrupts or raise SGIs need not populate this.

This patch adds a driver for ARM GICv2 systems, example GIC-400. Unlike the existing GIC driver in `include/drivers/arm/arm_gic.h`, this driver is optimised for GICv2 and does not support GICv3 systems in GICv2 compatibility mode. The driver interface has been implemented in `drivers/arm/gic/v2/gicv2_main.c`. The corresponding header is in `include/drivers/arm/gicv2.h`. Helper functions are implemented in `drivers/arm/gic/v2/gicv2_helpers.c` and are accessible through the `drivers/arm/gic/v2/gicv2_private.h` header.
