Benjamin Herrenschmidt 99c5b0fca1 bios/sdram: Use an LFSR to speed up pseudo-random number generation 
This speeds up the memory test by an order of magnitude, esp. on
cores without a hardware multiplier by getting rid of the
multiplication in the loop.

The LFSR implementation comes from microwatt's simple_random test
project.

Merge pull request #499 from DurandA/patch-2 
Add data dirs to manifest

Florent Kermarrec 8b9aa16d2e boards/platforms: update xilinx programmers. 2020-05-06 16:16:41 +02:00
Florent Kermarrec 3c34039b73 build/xilinx/vivado: ensure Vivado process our .xdc early. 
When generating the LitePCIe PHY wrappers from the .xci, Vivado is locking the
PCIe lanes to default locations that do not necessarily match the ones used in
the design.

Processing our constraints earlier makes Vivado use our constraints and not the
ones from the generated wrapper.

Florent Kermarrec b057858071 gen/fhdl/verilog: explicitly define input/output/inout wires. 
When integrating designs which set `default_nettype none, the top also needs
to explicitly define the type of the signals.

Florent Kermarrec 95b57899cd bios: remove usddrphy debug (we'll use a specific debug firmware to fix the usddrphy corner cases). 2020-05-05 16:27:21 +02:00

Florent Kermarrec 22bcbec03a boards: keep in sync with LiteX-Boards, integrate improvements. 
- create_programmer on all platforms.
- input clocks automatically constrainted.
- build/load parameters.
 2020-05-05 15:27:56 +02:00
Florent Kermarrec 28f85c7403 build/lattice/programmer: add UJProg (for ULX3S). 2020-05-05 13:31:58 +02:00
Florent Kermarrec 85ac5ef133 build/lattice/programmer: make OpenOCDJTAGProgrammer closer to OpenOCD programmer. 2020-05-05 12:17:12 +02:00
Florent Kermarrec 9a7f9cb87b build/generic_programmer: catch 404 not found when downloading config/proxy. 2020-05-05 12:16:29 +02:00
Florent Kermarrec d0b8daa005 build/platform: allow doing a loose lookup_request (return None instead of ConstraintError) and allow subname in lookup_request. 
In the platforms, insead of doing:
self.lookup_request("eth_clocks").rx
we can now do:
self.lookup_request("eth_clocks:rx")

This allows some try/except simplifications on constraints.
 2020-05-05 11:23:46 +02:00
Florent Kermarrec b8f9f83a8f build/openocd: add find_config method to allow using local config file or download it if not available locally. 2020-05-05 09:56:13 +02:00
Florent Kermarrec 9bef218ad6 cpu/microwatt: fix integration/crt0.S (thanks Benjamin Herrenschmidt).
