Govindraj Raja 306551362c feat(d128): add support for FEAT_D128 ... This patch disables trapping to EL3 when the FEAT_D128 specific registers are accessed by setting the SCR_EL3.D128En bit. If FEAT_D128 is implemented, then FEAT_SYSREG128 is implemented. With FEAT_SYSREG128 certain system registers are treated as 128-bit, so we should be context saving and restoring 128-bits instead of 64-bit when FEAT_D128 is enabled. FEAT_SYSREG128 adds support for MRRS and MSRR instruction which helps us to read write to 128-bit system register. Refer to Arm Architecture Manual for further details. Change the FVP platform to default to handling this as a dynamic option so the right decision can be made by the code at runtime.
