The workaround addresses the incorrect wiring of upper address bits in the A53 subsystem that corrupts TLBI and IC maintenance operations between A53 and A72 clusters. Previously the A72 CPUs (cpu@100, cpu@101) and cpu-map were removed from the TQMa8QM DTSI with an explicit comment "Due to missing workaround for ERR050104". With the software workaround is in place, remove the workaround-comment block and restore the full SMP topology.
