The definitions for the AArch64 FEAT_TPS and FEAT_TPSP system registers have been updated to align with the latest specification. The change replaces the use of tpmin*/tpmax* register pairs with individual tpcr* registers, ensuring correct behavior and compliance with current ARM architecture standards.
