Integrate black-parrot into LiteX and LiteX-BuildEnv

[mithro]

LiteX is an FPGA SoC generator that supports a wide range of FPGA boards and platforms. It currently support multiple soft-cpus, including multiple RISC-V implementations. You can find the details about supported CPUs on this wiki page -> https://github.com/enjoy-digital/litex/wiki/Soft-CPU

It would be awesome to see Black-Parrot in the LiteX system. It would let us very easily compare the resource usage of Black-Parrot to Rocket and VexRISCV.

LiteX-BuildEnv is my environment which uses LiteX to create images for many different FPGA boards. It supports Zephyr, Linux, Micropython and bare metal firmware.

You can find a diagram of this below;

There is also a Linux on LiteX VexRISCV repository which would be cool to port to use Black-Parrot as an alternative option.

You can find the existing CPUs at https://github.com/enjoy-digital/litex/tree/master/litex/soc/cores/cpu
Rocket is probably the closest configuration which can be found at https://github.com/enjoy-digital/litex/blob/master/litex/soc/cores/cpu/rocket/core.py

Nice we will take a look!

Completed.
