Since Issue B (November 2016) of the SMC Calling Convention document standard SMC calls are renamed to yielding SMC calls to help avoid confusion with the standard service SMC range, which remains unchanged. http://infocenter.arm.com/help/topic/com.arm.doc.den0028b/ARM_DEN0028B_SMC_Calling_Convention.pd A previous patch introduced a new define for yielding SMC call type. This patch updates the secure payload dispatchers (except the TSPD) to use this new define and also migrates the code to use the new terminology.
