+1
Just a note here that for Zynq and ZynqMP there should be doable to run
Microblaze in programmable logic with reusing fixed IPs.
There could be also other soft core CPUs which could do this on Xilinx
devices.
It means maybe moving this out of arm/arm64 to more generic location
would be one more step to consider as the part of this move.
