Florent Kermarrec 0a1ae7b413 setup.py: Expose litex_soc_gen and litex_periph_gen and sort console scripts. 2022-05-05 17:44:59 +02:00
Florent Kermarrec e8b6200225 tools: Add initial LiteX standalone SoC generator. 
Allow generating standalone SoC with CPU/Peripherals that can be re-integrated in
external design or top level LiteX SoCs.

Example of of use:
python3 litex_soc_gen.py --cpu-type=vexriscv --bus-standard=wishbone --build
python3 litex_soc_gen.py --cpu-type=naxriscv --bus-standard=axi-lite --build
 2022-05-05 17:36:34 +02:00
Florent Kermarrec e7cee80670 tools/litex_gen: Rename to litex_periph_gen to make it more explicit (And also to prepare for litex_soc_gen). 2022-05-05 17:36:22 +02:00
Florent Kermarrec 36ea82546f litex_setup: Allow specifying tag for --init --update. 
Allow installing from release tags, ex to install 2022.04 from scratch:
./litex_setup.py --tag=2022.04 --init --install --user.

To update to 2022.04 from a previous installation:
./litex_setup.py --tag=2022.04 --update

To update to latest (dev):
./litex_setup.py --updatelitex_setup: Allow specifying tag for --init --update.

software/bios: Fix build error for targets with sdcard but without main_ram_base
 2022-04-25 19:26:47 +02:00
Florent Kermarrec 63cda6c7b9 soc/add_ethernet: soc/add_etherbone: Add data_width parameter and allow 8-bit/32-bit core data_width. 2022-04-25 18:44:52 +02:00
Florent Kermarrec bdbb6c0b3f soc/add_etherbone: Add data_width parameter and allow 8-bit/32-bit core data_width. 2022-04-25 17:49:57 +02:00
Christian Klarhorst 6ca890ebc0 software/bios: Fix build error for targets with sdcard but without main_ram_base 
sdcardboot_from_bin assumes that the MAIN_RAM_BASE is set which is not always
the case. This commit deactivates the sdcardboot_from_bin support for targets
without main-ram. In those cases, the boot_from_json method can still be used.

- Increase similarities with other CPUs.
- Classify instance signals.
- Use Open instead of Signal on open ports.
- Switch pbus to AXILite instead of Wishbone.
- Directly connect AXI ports.
- Rename connect_jtag to add_jtag.
