Franck Jullien 1b22c6c0ad efinix: add a list of values to fix in xml
Sometimes the Python API of the interface designer produce a wrong XML
file. Values can be changed in the XML file with this new list.
For example:

fix_pll = [
	#      Tag              name                    properties / values
	("comp_output_clock", "mipi_clk",             [("out_divider", "20")]),
        ("comp_output_clock", "mipi_tx_clk_fastclk",  [("out_divider", "4"), ("phase_setting", "3")]),
        ("comp_output_clock", "mipi_tx_data_fastclk", [("out_divider", "4"), ("phase_setting", "1")]),
        ("comp_output_clock", "mipi_tx_slowclk",      [("out_divider", "16")])
]

platform.toolchain.ifacewriter.fix_xml += fix_pll

Franck Jullien 289c7fbf54 platform: fix add_sources
If the Builder class is not used to build the projet, platform sources
is still a list of tupples with 4 elements.

For now, we don't handle file copy when Builder is not used but at least
it won't crash.

Franck Jullien 9de86c84d6 efinix:dbparser: add get_pad_name_from_pin and use it
get_gpio_instance_from_pin returned the pad name.
It now returns the gpio block name.

To get the pad name, there is now get_pad_name_from_pin.

Florent Kermarrec f6d6611a81 software/liblitedram: Introduce SDRAM_PHY_DELAY_JUMP and set to 4 on 7-Series instead of 1 to improve calibration robustness on some boards.
This is for example required on the STLV7325 board.

Florent Kermarrec 82daa48e09 software/bios/libbase: Always do memtest/memspeed when main_ram is present.

Florent Kermarrec 1b62f14230 build: Add initial OpenFPGA build backend with SOFA support and minimal blinky example.
OpenFPGA should be installed by following installation steps from https://github.com/lnis-uofu/OpenFPGA.
SOFA can be cloned from https://github.com/lnis-uofu/SOFA

Environment variables then need to be set:
export LITEX_ENV_OPENFPGA=/PATH_TO_OPENFPGA
export LITEX_ENV_OPENFPGA_SOFA=/PATH_TO_SOFA

A simple blinky test design is provided and can be built by executing blinky.py.

Florent Kermarrec c494ea231b cpu: Add initial NaxRiscv support (From out of tree prototyping in litex_naxriscv_test).
- Supporting rv32ima for now.
- No interrupt support yet.
- AXI4 direct interfaces to LiteDRAM (fixed at 128-bit for now).
- AXI4-Lite interfaces to LiteX main bus.
- Pre-generated netlist used for now (need to allow customization/re-generation).
- Running in simulation with: litex_sim --cpu-type=naxriscv
- Running on hardware with: python3 -m litex_boards.targets.digilent_arty --cpu-type=naxriscv --build --load

Florent Kermarrec 38a047bed1 cpu: Add initial NEORV32 support (From out of tree prototyping in litex_neorv32_test repo).
- Only configured for rv32i for now (need to create variants).
- I/DBus interfaces probably not optimal (latency).
- Converted from VHDL to Verilog through GHDL-Yosys-Synth (should also support direct VHDL use with toolchains supporting it).
- Interrupt not yet implemented.
- Running in simulation with litex_sim --cpu-type=neorv32.
- Running on Arty with: python3 -m litex_boards.targets.digilent_arty --cpu-type=neorv32 --build --load:
