NOTE Recommend Host controllers move to taking EHS length from UTRD, and in UFS-5, it will be mandatory." So, when UFSHCI 4.0 doesn't support EHS Length field in UTRD, we could use EHS Length field in CMD UPIU. This patch aims to remove the limitation that advanced RPMB only works when EHS length is supported in UTRD.
