Cortex-A710 erratum 2291219 is a Cat B erratum that applies to revisions r0p0, r1p0, and r2p0, and is fixed in r2p1. The workaround is to set CPUACTLR2_EL1[36] to 1 before the power down sequence that sets CORE_PWRDN_EN. This allows the cpu to retry the power down and prevents the deadlock. TF-A never clears this bit even if it wakes up from the wfi in the sequence since it is not expected to do anything but retry to power down after and the bit is cleared on reset.
