dev: Added LupV script to configs
This commit adds run_lupv.py, the script to run the LupVBoard, as well
as a README that details how to set up your system in order to run
the LupIO devices.

+# README
+
+This README details how to build a RISCV full system that utilizes the
+lupIO devices. The LupIO devices were created by Professor Joël
Porquet-Lupine,
+and more information about the device can be found here
(https://luplab.cs.ucdavis.edu/assets/lupio/wcae21-porquet-lupio-paper.pdf).
The specs for each individual device can
+be found here (https://gitlab.com/luplab/lupio/lupio-specs), and the Linux
drivers
+for each of these devices can be found here
(https://gitlab.com/luplab/lupio/linux).
+
+In order to run this system, you need the following:
+
+* `run_lupv.py`
+* a built version of the lupIO gem5 repo
+* bbl
+* disk image
+
+Both the bbl and a working disk image can be found on the LupIO+gem5 Google
+Drive. In addition, instructions to build a version of Linux with the lupIO
+drivers are there, but should not be needed.
+
+In order for `run_lupv.py` to work in its current state, move it within the
+gem5 directory.
+
+Once you have everything set up, you can run the RISCV full system by using
+the following command line prompt. Note that for the cpu type, you can
choose
+between `atomic` and `simple` modes.
+
+``` bash
+[gem5 binary] gem5/run_lupv.py [path to bbl] [path to the disk image] [cpu
type] [num cpus]
+```
+
+example:
+
+```bash
+gem5/build/RISCV/gem5.opt gem5/run_lupv.py bbl rootfs.img atomic 1
+```
+
+Once you've started the gem5 simulation, you can open up a separate
terminal
+and use m5term to connect to the simulated console. The port number will be
+specified in the gem5 simulation.
+
+example:
+
+```bash
+m5term localhost 3456
+```
+
+This should allow you to run busybox, in which you can see the LupIO
device at
+work!
