Move plat/common source file definitions to generic Makefiles These source file definitions should be defined in generic Makefiles so that all platforms can benefit. Ensure that the symbols are properly marked as weak so they can be overridden by platforms. NOTE: This change is a potential compatibility break for non-upstream platforms.

Introduce `el3_runtime` and `PSCI` libraries This patch moves the PSCI services and BL31 frameworks like context management and per-cpu data into new library components `PSCI` and `el3_runtime` respectively. This enables PSCI to be built independently from BL31. A new `psci_lib.mk` makefile is introduced which adds the relevant PSCI library sources and gets included by `bl31.mk`. Other changes which are done as part of this patch are: * The runtime services framework is now moved to the `common/` folder to enable reuse. * The `asm_macros.S` and `assert_macros.S` helpers are moved to architecture specific folder. * The `plat_psci_common.c` is moved from the `plat/common/aarch64/` folder to `plat/common` folder. The original file location now has a stub which just includes the file from new location to maintain platform compatibility. Most of the changes wouldn't affect platform builds as they just involve changes to the generic bl1.mk and bl31.mk makefiles. NOTE: THE `plat_psci_common.c` FILE HAS MOVED LOCATION AND THE STUB FILE AT THE ORIGINAL LOCATION IS NOW DEPRECATED. PLATFORMS SHOULD MODIFY THEIR MAKEFILES TO INCLUDE THE FILE FROM THE NEW LOCATION.

Introduce interrupt registration framework in BL3-1 This patch introduces a framework for registering interrupts routed to EL3. The interrupt routing model is governed by the SCR_EL3.IRQ and FIQ bits and the security state an interrupt is generated in. The framework recognizes three type of interrupts depending upon which exception level and security state they should be handled in i.e. Secure EL1 interrupts, Non-secure interrupts and EL3 interrupts. It provides an API and macros that allow a runtime service to register an handler for a type of interrupt and specify the routing model. The framework validates the routing model and uses the context management framework to ensure that it is applied to the SCR_EL3 prior to entry into the target security state. It saves the handler in internal data structures. An API is provided to retrieve the handler when an interrupt of a particular type is asserted. Registration is expected to be done once by the primary CPU. The same handler and routing model is used for all CPUs. Support for EL3 interrupts will be added to the framework in the future. A makefile flag has been added to allow the FVP port choose between ARM GIC v2 and v3 support in EL3. The latter version is currently unsupported. A framework for handling interrupts in BL3-1 will be introduced in subsequent patches. The default routing model in the absence of any handlers expects no interrupts to be routed to EL3.

Remove early_exceptions from BL3-1 The crash reporting support and early initialisation of the cpu_data allow the runtime_exception vectors to be used from the start in BL3-1, removing the need for the additional early_exception vectors and 2KB of code from BL3-1.

Move context management code to common location The upcoming Firmware Update feature needs transitioning across Secure/Normal worlds to complete the FWU process and hence requires context management code to perform this task. Currently context management code is part of BL31 stage only. This patch moves the code from (include)/bl31 to (include)/common. Some function declarations/definitions and macros have also moved to different files to help code sharing. Change-Id: I3858b08aecdb76d390765ab2b099f457873f7b0c

Move bakery algorithm implementation out of coherent memory This patch moves the bakery locks out of coherent memory to normal memory. This implies that the lock information needs to be placed on a separate cache line for each cpu. Hence the bakery_lock_info_t structure is allocated in the per-cpu data so as to minimize memory wastage. A similar platform per-cpu data is introduced for the platform locks. As a result of the above changes, the bakery lock api is completely changed. Earlier, a reference to the lock structure was passed to the lock implementation. Now a unique-id (essentially an index into the per-cpu data array) and an offset into the per-cpu data for bakery_info_t needs to be passed to the lock implementation.

Add Performance Measurement Framework(PMF) This patch adds Performance Measurement Framework(PMF) in the ARM Trusted Firmware. PMF is implemented as a library and the SMC interface is provided through ARM SiP service. The PMF provides capturing, storing, dumping and retrieving the time-stamps, by enabling the development of services by different providers, that can be easily integrated into ARM Trusted Firmware. The PMF capture and retrieval APIs can also do appropriate cache maintenance operations to the timestamp memory when the caller indicates so. `pmf_main.c` consists of core functions that implement service registration, initialization, storing, dumping and retrieving the time-stamp. `pmf_smc.c` consists SMC handling for registered PMF services. `pmf.h` consists of the macros that can be used by the PMF service providers to register service and declare time-stamp functions. `pmf_helpers.h` consists of internal macros that are used by `pmf.h` By default this feature is disabled in the ARM trusted firmware. To enable it set the boolean flag `ENABLE_PMF` to 1. NOTE: The caller is responsible for specifying the appropriate cache maintenance flags and for acquiring/releasing appropriate locks before/after capturing/retrieving the time-stamps.

Introduce interrupt handling framework in BL3-1 This patch adds a common handler for FIQ and IRQ exceptions in the BL3-1 runtime exception vector table. This function determines the interrupt type and calls its handler. A crash is reported if an inconsistency in the interrupt management framework is detected. In the event of a spurious interrupt, execution resumes from the instruction where the interrupt was generated. This patch also removes 'cm_macros.S' as its contents have been moved to 'runtime_exceptions.S' Change-Id: I3c85ecf8eaf43a3fac429b119ed0bd706d2e2093

# in BL31. This defaults to being present in DEBUG builds only
Make the BL3-1 crash reporting optional This patch makes the console crash dump of processor register state optional based on the CRASH_REPORTING make variable. This defaults to only being enabled for DEBUG builds. This can be overridden by setting a different value in the platform makefile or on the make command line.
