target-arm: add SCTLR_EL3 and make SCTLR banked
Implements SCTLR_EL3 and uses secure/non-secure instance when needed. Signed-off-by: Fabian Aggeler <aggelerf@ethz.ch> Signed-off-by: Greg Bellows <greg.bellows@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> --- v9 -> v10 - Fix SCTLR to use opc0 instead of cp v8 -> v9 - Remove the v8 check in arm_cpu_reset when setting regs[15] - Fix SCTLR definition component order v5 -> v6 - Changed _el field variants to be array based - Consolidate SCTLR and SCTLR_EL1 reginfo entries
