Florent Kermarrec ce254208ff beaglewire: Review/Cleanup for consistency with other targets.
- Now uses regular UART.
- Build tested with: ./quertyembedded_beaglewire.py --cpu-type=serv --build
- Can still be build with Crossover UART with --uart-name=crossover+bridge.

Florent Kermarrec 8f1c15bdb8 ebaz4205: Remove PS7 support for now (since untested and we'll avoid the .xci in LiteX-Boards repository). 2021-08-31 18:56:47 +02:00
Dhiru Kholia 781d83bab6 Add support for EBAZ4205 'Development' Board
Usage:

```
./ebaz4205.py --cpu-type=vexriscv --build --load
```

```
$ pwd
litex-boards/litex_boards/targets
```

Tip: Use `GTKTerm` to connect to /dev/ttyUSB0 (usually) and interact
with the LiteX BIOS.

Note: The `PS7` stuff remains untested via LiteX for now.

Yoshimasa Niwa fc78c96444 FIX: OrangeCrab Feather SPI pad name
**Problems**

`SPIMaster` pad names are `clk`, `cs_n`, `mosi`, and `miso`.
However, `feather_spi` is using `sck` instead of `clk`, therefore
it is not able to use as-is for `SPIMaster`, for example,
with `add_spi` on Linux On LiteX VexRiscv.

**Solution**

In fact, `spisdcard` and other SPI related pad names are
using `clk`, only `feather_spi` is using `sck`.
Therefore, rename `sck` to `clk`.

Dan Callaghan cc9e39286a lattice_crosslink_nx_evn: allow specifying the FPGA device
This board is documented as having the LIFCL-40-9BG400C part, but some
versions of the board exist which were fitted with LIFCL-40-8BG400CES,
an engineering sample part. The distinction is important because the
engineering sample requires a different device ID to be embedded in the
bitstream. If you try to build a bitstream for LIFCL-40-9BG400C and load
it onto LIFCL-40-8BG400CES the configuration fails (indicated by the red
"INITN" LED on this board).

Accept --device to allow the user to specify which FPGA part their board
has.

We can still try to reduce it, but enabling Master should not use that much LCs.
