According to the chromecast kernel sources (which seem to have all the
gtv stuff in them), they changed the CPU core between minor versons
of the 88de3100:
PJ4 based:
- MV88DE3100_BG2_A0
- MV88DE3100_BG2_A1
Cortex-A5 or Cortex-A9 based:
- MV88DE3100_BG2_CD
- MV88DE3100_BG2_CZ
- MV88DE3100_BG3
Those are Kconfig strings, I don't know how those correspond to
chip identification registers or labels printed on the SoC package.

/proc/cpuinfo will tell you what core you have, see
http://wiki.casthacks.com/index.php?title=Google_ChromeCast_Specs:
CPU implementer : 0x41 # 0x41 == ARM Ltd
CPU architecture: 7 # 0x07 == ARMv7
CPU variant : 0x3 # 0x03 == Core revision r3
CPU part : 0xc09 # 0xc0? == Cortex-A?, 0xc09 == A9
CPU revision : 0 # 0x00 == minor revision r3p0
On http://forum.gtvhacker.com/star-vap430-f40/topic972.html, I found
this for a PJ4 based 88de3100:
CPU implementer : 0x56
CPU architecture: 7
CPU variant : 0x2
CPU part : 0x584
CPU revision : 1
Comparing those to other bits I found on the web, it actually seems to
be a PJ4B rather than the original PJ4.
