Check with whoever you'd be getting the hardware from about a BSP.
And yes, it should be supported upstream at some point.

The cache line is 64 bytes. As with e500mc, there is a "dcbz32" mode
for compatibility, though you probably lose much of the performance
benefit of dcbz, and it might upset other software that properly checks
for the cache line size but doesn't use dcbzl.
