Jeenu Viswambharan caa84939a4 Add support for handling runtime service requests ... This patch uses the reworked exception handling support to handle runtime service requests through SMCs following the SMC calling convention. This is a giant commit since all the changes are inter-related. It does the following: 1. Replace the old exception handling mechanism with the new one 2. Enforce that SP_EL0 is used C runtime stacks. 3. Ensures that the cold and warm boot paths use the 'cpu_context' structure to program an ERET into the next lower EL. 4. Ensures that SP_EL3 always points to the next 'cpu_context' structure prior to an ERET into the next lower EL 5. Introduces a PSCI SMC handler which completes the use of PSCI as a runtime service Change-Id: I661797f834c0803d2c674d20f504df1b04c2b852 Co-authored-by: Achin Gupta <achin.gupta@arm.com>		2014-02-17 18:51:44 +00:00
