Bryan O'Donoghue 520f864e66 bl1-smc-handler: Ensure the lower-order 16 bits of SPSR are programmed A bug recently fixed in bl2/aarch32/bl2_el3_entrypoint.S relates to programming the lower-order 16 bits of the SPSR to populate into the CPSR on eret. The BL1 smc-handler code is identical and has the same shortfall in programming the SPSR from the platform defined struct entry_point_info->spsr. msr spsr, r1 will only update bits f->[31:24] and c->[7:0] respectively. In order to ensure the 16 lower-order processor mode bits x->[15:8] and c->[7:0] this patch changes msr spsr, r1 to msr spsr_xc, r1. This change ensures we capture the x field, which we are interested in and not the f field which we are not.
