Hi LiZhiJian,
just one thing I noticed in your call stack, your $Subject talks about AArch64,
and you end up in arm_v7m_mmu_idx_for_secstate,
which means that ARM_FEATURE_M is detected, so definitely something looks off
when it comes to the feature bits..
That's true, so i guessboldly migration across this FBC are not trustable.
the FBC changed the feature bits offset. Previously ARM_FEATURE = 11(source
side), after this commit(destination side), it turned ARM_FEATURE = 9.
Ciao,
Claudio
