Manish Pandey 1cbe42a510 fix(el3_runtime): allow SErrors when executing in EL3 ... SCR_EL3.EA is set to 1 in BL31 initialization and is cleared before entering to lower ELs(except for RAS FFH case "HANDLE_EA_EL3_FIRST_NS"). The cleared value persist even during run time when execution comes back to EL3. When SCR_EL3.EA is 0 and execution state is EL3, Async EAs(delivered as SErrors) are implicitly masked and hence any Async EA by EL3 will remain pending and will trap at the exception level EA is targeted to and unmasked when entering lower EL. This causes unexpected EA at lower EL. This is a very rare to get SError in EL3 until unless there is any programming error. This patch sets SCR_EL3.EA to 1 when entering EL3 from lower EL.
