Florent Kermarrec 45494f60e0 targets: Change SoC/Software headers generation behaviour (Now only generated with --build).
Re-generating the SoC/Software headers was causing some un-expected behaviours for users not familiar
with the flow. For example doing a --load with a different configuration, was re-generating the Software
headers and messing up things when trying to run software on the SoC.

Florent Kermarrec a611f035d6 targets: Move CRG before SoCCore init (More logical and simplify some specific reset schemes) and switch SoCCore to one line when possible.
Moving CRG simplify reset with NaxRiscv debug module and is in fact more logical.
Also do some minor updates/cosmetic changes while touching CRG/SoCCore.

Florent Kermarrec cc8da9d341 targets: Simplify imports and switch to LiteXSocArgumentParser.
CPU parameters are now selectively exposed to the user:
./digilent_arty.py --cpu-type=vexriscv_smp --help will show VexRiscv-SMP parameters.
./digilent_arty.py --cpu-type=naxriscv --help will show NaxRiscv parameters.

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.
