Florent Kermarrec 621d45cd9e digilent_arty: Review and improve CRG to avoid specific yosys+nextpnr code.
sys4x/sys4x_dqs/idelay clks can be disabled when integrated-main-ram is used.

Victor Suarez Rovere db77ea5c7a Add tweaks to Arty board to support yosys+nextpnr toolchain 2022-01-24 02:06:34 -03:00
Florent Kermarrec fccb952c4b target: Remove ident_version=True no longer required. 2022-01-18 17:13:02 +01:00
Florent Kermarrec 7114911cea targets: --no-ident-version is now directly provided by LiteX, remove it on targets implementing it. 2022-01-18 16:47:38 +01:00
Florent Kermarrec 16171282c8 digilent_arty/CRG: Add with_rst parameter to be able to easily disable rst.
On Arty, cpu_rst pin is connected to a button but also to USB-UART which also
resets the SoC when USB-UART is connected which is in some case not wanted.

with_rst provides an easy way to disable rst by setting it to False.

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

Florent Kermarrec 68fb163a27 targets: Remove spiflash mapping on targets where it's no longer useful. 2021-09-14 18:35:13 +02:00
Florent Kermarrec 7fa22a494b arty: Switch SPI Flash rate to 1:2 (DDR) (Possible on Arty since SPI Flash's clk does not require use of STARTUPE2).
On the Digilent Arty, the SPI Flash's clk is connected to CCLK (that can be driven
through the STARTUPE2) but also to another generic IO that can be use to drive the
clock through DDR primitives.

Florent Kermarrec a3f479837c digilent_arty: Allow exposing raw PMOD IOs (for tests with MicroPython). 2021-07-21 13:50:12 +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 7442639a5e targets/digilent_arty: Add default value for CRG's with_mapped_flash.
Otherwise break retro-compat on external design importing CRG without passing this new parameter.

Florent Kermarrec 5bfeb999e4 targets/digilent_arty/flash: Simplify, use Quad mode and sys_clk (fast enough ~5MB/s). 2021-04-26 16:30:35 +02:00

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.

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
