Current RAS framework in TF-A only supports handling errors originating from NS world but the HANDLE_EA_EL3_FIRST flag configures it for all lower Els. To make the current design of RAS explicit, rename this macro to HANDLE_EA_EL3_FIRST_NS and set EA bit in scr_el3 only when switching to NS world. Note: I am unaware of any platform which traps errors originating in Secure world to EL3, if there is any such platform then it need to be explicitly implemented in TF-A Signed-off-by: Manish Pandey <manish.pandey2@arm.com> Change-Id: If58eb201d8fa792c16325c85c26056e9b409b750
