We already have specific constraints for SCTLR_EL1.{EE,E0E}, and
making them depend on FEAT_AA64EL1 is just buggy.Looking at the spec, I see that they depend on FEAT_MixedEnd and FEAT_MixedEndEL0, not on FEAT_AA64EL1. They are already in the right place in config.c. Reviewed-by: Fuad Tabba <tabba@google.com> Cheers, /fuad
