---------
-LiteX is a MiSoC-based SoC builder using Migen as Python DSL that can be used
-to create SoCs and full FPGA designs.
-
-LiteX provides specific building/debugging tools for high level of abstraction
-and compatibily with the LiteX core ecosystem.
-
-Think of Migen as a toolbox to create FPGA designs in Python and LiteX as a
-toolbox to create/develop/debug FPGA SoCs in Python.
-
-
-Typical LiteX design flow:

- +---------------+

-LiteX already supports various softcores CPUs: LM32, Mor1kx, PicoRV32, VexRiscv
-and is compatible with the LiteX's Cores Ecosystem:

-[> Sub-packages
----------------
-gen:
- Provides specific or experimental modules to generate HDL that are not integrated
- in Migen.
-
-build:
- Provides tools to build FPGA bitstreams (interface to vendor toolchains) and to
- simulate HDL code or full SoCs.
-
-soc:
- Provides definitions/modules to build cores (bus, bank, flow), cores and tools
- to build a SoC from such cores.
-
-boards:
- Provides platforms and targets for the supported boards. All Migen's platforms
- can also be used in LiteX. The boards present in the LiteX repository are the
- official ones that are used for development/CI. More boards are available at:

------------------------------------------
-TimVideos.us has done an awesome job for setting up a LiteX environment easily in

-
-It's recommended for newcomers to go this way. Various FPGA boards are supported
-and multiple examples provided! You can even run Linux on your FPGA using LiteX
-very easily!
-
-Migen documentation can be found here: https://m-labs.hk/migen/manual
-
-[> Quick start guide (for advanced users)
------------------------------------------
-0. Install Python 3.5+ and FPGA vendor's development tools.
-
-1. Install Migen/LiteX and the LiteX's cores:
- wget https://raw.githubusercontent.com/enjoy-digital/litex/master/litex_setup.py
- chmod +x litex_setup.py
- ./litex_setup.py init install --user (--user to install to user directory)
- Later, if you need to update all repositories:
- ./litex_setup.py update
-
-2. Install a RISC-V toolchain:
- wget https://static.dev.sifive.com/dev-tools/riscv64-unknown-elf-gcc-8.1.0-2019.01.0-x86_64-linux-ubuntu14.tar.gz
- tar -xvf riscv64-unknown-elf-gcc-8.1.0-2019.01.0-x86_64-linux-ubuntu14.tar.gz
- export PATH=$PATH:$PWD/riscv64-unknown-elf-gcc-8.1.0-2019.01.0-x86_64-linux-ubuntu14/bin/
-
-3. Build the target of your board...:
- Go to litex-boards/litex_boards/**/targets (** being community/official/partner) and execute the target you want to build
-
-4. ... and/or install Verilator and test LiteX on your computer:
- Download and install Verilator: http://www.veripool.org/
- On Fedora:
- sudo dnf install libevent-devel json-c-devel
- On Ubuntu:
- sudo apt install libevent-dev libjson-c-dev
- run: litex_sim
-
-5. Run a terminal program on the board's serial port at 115200 8-N-1.
- You should get the BIOS prompt.
