RAS extensions are mandatory for ARMv8.2 CPUs, but are also optional extensions to base ARMv8.0 architecture. This patch adds build system support to enable RAS features in ARM Trusted Firmware. A boolean build option RAS_EXTENSION is introduced for this. With RAS_EXTENSION, an Exception Synchronization Barrier (ESB) is inserted at all EL3 vector entry and exit. ESBs will synchronize pending external aborts before entering EL3, and therefore will contain and attribute errors to lower EL execution. Any errors thus synchronized are detected via. DISR_EL1 register. When RAS_EXTENSION is set to 1, HANDLE_EL3_EA_FIRST must also be set to 1.
