I David,

When I booted up 4.5-rc4 kernel on CN68xx board, both pass 1.1 and pass 
2.2 reports:

Kernel panic - not syncing: OCTEON II DCache prefetch workaround not in 
place (cfa00000).
Please build kernel with proper options (CONFIG_CAVIUM_CN63XXP1).

According to the description of he option, it should just have impact on 
63xx pass 1.x. It looks confusing.

Any hint is appreciated?

Thanks,
Yang
