DSU Erratum 2900952 is a Cat B erratum that applies to some DSU-120 implementations of revision r2p0 and is fixed in r2p1. This erratum is fixed in certain implementations of r2p0 which can be determined by reading the IMP_CLUSTERREVIDR_EL1[1] register field where a set bit indicates that the erratum is fixed in this part.
The workaround is to set the CLUSTERACTLR_EL1 bits [21:20] to 0x3 which ignores CBusy from the system interconnect and setting CLUSTERACTLR_EL1 bit [8] to 1 to assert CBusy from DSU to all the cores when DSU is busy.
