Florent Kermarrec 00ff61baa9 targets: Simplify clock domains and remove useless reset_less.
rst was not directly assigned/used on reset_less clock domains, so reset_less
property was not really useful. With the changes on stream.CDC, having a rst
(Even fixed at 0) is now mandatory on clock domains involved in the CDC, so this
also fixes targets.

Florent Kermarrec 2a206def0f targets/ecp5/ddr3: Uniformize cd_sys2x (reset_less). 2022-03-22 17:32:35 +01:00
Florent Kermarrec 9d452b0d74 targets: Create target_group for target arguments. 2022-03-21 18:37:40 +01:00
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 f52a915487 lambdaconcept_ecpix5: Add initial Video support at 640x480 (with Terminal/Framebuffer).
I2C intialization code adapted from https://github.com/ultraembedded/ecpix-5.

Tested with:
- python3 -m litex_boards.targets.lambdaconcept_ecpix5 --cpu-type=firev --with-video-terminal --build --load
- python3 -m litex_boards.targets.lambdaconcept_ecpix5 --cpu-type=firev --with-video-framebuffer --build --load

Florent Kermarrec 53dc00eab7 targets/parser: Rely on argparse.ArgumentDefaultsHelpFormatter to provide default in help description.
Also do minor adjustments while doing this.

Florent Kermarrec 1ca8ef97a1 targets/add_sdram: Specific size only when useful (ie for targets with > 1GB of RAM). 2021-03-29 16:03:19 +02:00
Florent Kermarrec ba01776432 targets/add_sdram: Simplify call by removing useless arguments.
- main_ram mem_map is now directly used by add_sdram when origin is None.
- max_sdram_size/min_l2_data_width are no longer exposed as targets arguments this can
still be used enforced directly in the few cases it is useful.
