Vikram Kanigiri 28e3d2688a Rework handover interface between BL stages ... This patch reworks the handover interface from: BL1 to BL2 and BL2 to BL3-1. It removes the raise_el(), change_el() and run_image() functions as they catered for code paths that were never exercised. BL1 calls drop_el() to jump into BL2 instead of doing the same by calling run_image(). Similarly, BL2 issues the SMC to transfer execution to BL3-1 through BL1 directly. Only x0 and x1 are used to pass arguments to BL31. These arguments and parameters for running BL3-1 are passed through a reference to a 'el_change_info_t' structure. They were being passed value in general purpose registers earlier. Change-Id: Id4fd019a19a9595de063766d4a66295a2c9307e1		2014-05-20 16:36:31 +01:00
