Current Cache Size ID Register (ccsidr_el1) has two "flavors" depending on whether FEAT_CCIDX is implemented or not. When FEAT_CCIDX is implemented Associativity parameter is coded on bits [23:3] and NumSets parameter on bits [55:32]. When FEAT_CCIDX is not implemented then Associativity parameter is coded on bits [12:3] and NumSets parameter on bits [27:13]. Current U-Boot code does not check whether FEAT_CCIDX is implemented and always parses ccsidr_el1 as if FEAT_CCIDX was not implemented. This is of course wrong on systems where FEAT_CCIDX is implemented. This patch fixes that problems and tests whether FEAT_CCIDX is implemented or not and accordingly parses the ccsidr_el1 register.
