Florent Kermarrec 877bc4b45e targets: Use full imports (vendor_board). 2022-05-02 12:55:11 +02:00
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 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 773444a7dd targets: Switch to get_bios_filename/get_bitstream_filename. 2022-03-17 09:21:05 +01:00
Florent Kermarrec fccb952c4b target: Remove ident_version=True no longer required. 2022-01-18 17:13:02 +01:00
Florent Kermarrec 53dc00eab7 targets/parser: Rely on argparse.ArgumentDefaultsHelpFormatter to provide default in help description.
Also do minor adjustments while doing this.

Dan Callaghan 74c2178150 lattice_crosslink_nx_evn: don't set MASTER_SPI_PORT=SERIAL
Setting MASTER_SPI_PORT=SERIAL causes the SPI flash pins to be reserved
for use by the sysCONFIG logic, and prevents user logic from assigning
them. This made it impossible to have a Litex design which accesses the
SPI flash on this board.

Remove the setting, so that we get the default behaviour which permits
user logic to assign these pins. In the unlikely event that someone
needs the pins to stay reserved for sysCONFIG after configuration (I'm
not sure why this would be needed) they could explicitly add this
command in their design.

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.

Florent Kermarrec 55ba0591df targets: Remove SpiFlash imports (Obsolete since integration is provided by LiteX). 2021-07-27 19:35:19 +02:00
Joey Bushagour 1920db3535 Add with_led_chaser argument to constructor of boards using LedChaser submodule. 2021-07-06 16:39:37 -05:00
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.

Florent Kermarrec e2de69496a targets/lattice_crossing: Avoid direct override of SoCCore.mem_map (break default SoCore.mem_map with updated imports). 2021-03-25 22:41:26 +01:00
Florent Kermarrec 8a3cacae32 boards: Add Vendor prefix to platforms/targets name when useful and when multiple boards from the same vendor. (With Retro-Compat on the imports). 2021-03-25 14:11:17 +01:00
