As our offline discussion, Chetan found an issue with the value of MASK_CCSIDR so create this issue to have a record and tracking the fix.
Per BSA spec, if FEAT_CCIDX is implemented, the number of Sets [55:32] and the associativity of Caches [23:3] can be different on each PE's CCSIDR_EL1 registers. Now the value of MASK_CCSIDR is 0xFFFFFF8 so the Permitted architectural difference in "The number of Sets [55:32]" is wrongly identified as a failure.
