Varun Wadekar df56e9d199 fix(bl31): pass the EA bit to 'delegate_sync_ea' During a synchronous exception, the 'enter_lower_el_sync_ea' handler tests the ESR_EL3 EA bit and calls 'report_unhandled_exception', if it is not set. EA = 0 and IFSC = SEA, seems to be a contradiction. EA provides further classification of a synchronous abort. A synchronous abort is determined by the IFSC value on an instruction fetch synchronous abort. As a result, EA will never be set to 1 on an instruction fetch synchronous abort and 'report_unhandled_exception' should not be called. This patch removes this behavior to allow the platform to handle the exception.
