Yep that’s exactly the sort of setup I am referring to. 

Not sure about 'virtual/xilinx-sdk' as the virtual target, maybe something like 'virtual/zynq7-platform-headers' would be more descriptive (and would work for microblaze too)? However as long as there is consistency that’s all that matters.

As for the location in the sysroot, probably worth following what the kernel does for kernel source for kernel modules, something like '${STAGING_DIR_HOST}/usr/src/zynq7-platform/'?

Nathan
