HALF_A (EVEN) means only A is enabled and HALF_B (ODD) means only B is enabled. For DD1X, the values of UNK_OFF, UNK_ON, UNK_HALF_A and UNK_HALFB were added because early parts did not have the fuses blown correctly, so the cache repairs may not have worked. This value is set by the platform which can get the chips value by running the mss_cen_get_ecid function.
Note: Cronus and Firmware plus our initfiles do not really support any of the UNK values.  It is the responsibility of the platform to map the UNK values to the appropriate value of OFF/ON/HALF_A/HALF_B</description>
