Forgot? Or is it that there are no Bluetooth parts suited for OSH?

Yes, of course, switching/bridging is always something to avoid and to use only if really necessary to implement the desired features. Using a PCIe bridge without being really necessary would be bad design and just add to the costs.

The POWER microarchitecture implements the PowerPC ISA (as well as the more recent Power ISA), so yes, the POWER9 is a PPC and the Talos II is a PPC-based system.

I tend to think of PPCs as all CPUs implementing the 32-bit and/or 64-bit PowerPC ISA :-)

The block diagram looks good :-)
