Add improved logic to detect the exact CX2388[578] A/V core that is being probed. Also cleaned up detection and logging for CX2310[12], CX2583[67], and CX2584[0123] cores and chips. Also added code to identify a CX2388[578] A/V decoder core that is not responding properly. Typical symptoms include registers 0x00-0xff responding properly but all other registers returning the same value (0x13 and 0x5 have been observed). This state will cause proper detection of '885 vs. '887 vs. '888 to fail and the chip won't respond to get configured properly anyway. I have no method of reseting the core to a working state at this time; but I didn't try too hard to work one out either. The problem likely only occurs in development. I suspect configuring the SYS PLL VCO to oscillate too slowly (286.3 MHz?) before post divide may be the root cause, when encountered.
