Florent Kermarrec cb9f0fb1b0 ci/test_cpu: Install OpenRISC GCC toolchain in CI and add mor1kx to test_cpu. 2021-10-26 15:45:43 +02:00
Florent Kermarrec 71a91eac15 test: Rename test_boot.py to test_cpu.py. 2021-10-26 08:35:16 +02:00
Florent Kermarrec 47b3c9bc08 soc/interconnect/packet: Remove last_be support in LiteX, specialized Packetizer/Depacketizer have been moved to LiteEth to simplify development and avoid eventual regresion on others cores.
As seen during the last LiteEth developments, last_be data qualifier is not easy to handle correctly and should be replaced by a simpler data qualifier (similar to AXI's tkeep/tstrb). It will
be easier to do so by having a local copy of Packetizer/Depacketizer directly in LiteEth (still with last_be support) and work on the simpler data qualifier in LiteX (and test it on LitePCIe).

Florent Kermarrec 8e448592f0 interconnect/packet: Revert old last/ready logic handling (new one breaks test_packet) and comment out test_packet2 tests (does not seems to be working with previous last/ready handling). 2021-10-23 18:21:47 +02:00
Florent Kermarrec 59fd2d31c7 test/test_packet2: Fix imports. 2021-10-23 17:54:00 +02:00
Florent Kermarrec 32bb2554bc test: Rename new test_packet/stream to test_packet2/stream2 and revert old tests.
Old and new tests are complementary and would need to be merged.

Florent Kermarrec 99f3498f2d cores/icap/ICAP: Add Register read capability.
Useful to get some internal status, ex the IDCode or know if the executed bistream
in a multiboot configuration is the operational or fallback one.

Leon Schuermann a568b7e26a test_packet.py: test randomly generated headers
Also includes some fixes for the non-last_be test path such that the
expected behavior is the one currently oberserved with the Packetizer
and Depacketizer.

Florent Kermarrec 1ce48a973b clock/lattice_ecp5: Fix and rework 4-output solver implementation.
The implementation was causing regressions on actual designs, rework done:
- Only keep a common iteration loop as before.
- Add iteration on CLKO dividers (to fall in the VCO range).
- Do the iterations as before, if while doing it we find a clock suitable for feedback: just use it.
- If no feedback clock has been found: create it (if at least one free output available, if not raise an error).

George Hilliard 8954041a93 clock/lattice_ecp5/ECP5PLL: Only consider non-dpa clocks as feedback
Dynamically adjusting the phase of a feedback will cause it to unlock.
The phase adjust ports are shared by all the outputs, so there is no
technical way to prevent this.  Allow the user to indicate that they
will not adjust a clock when requesting an output by setting
uses_dpa=False, and only consider those that the user has promised not
to use.

Florent Kermarrec f31f9a20f0 boards: remove and switch to litex_boards.
Keeping board definition files directly in LiteX is no longer useful since we are already relying on board
definitions files from LiteX-Boards (https://github.com/litex-hub/litex-boards) in various benches/projects
and having definitions files directly in LiteX creates confusion/additional work.

For projects using board definition files from LiteX, the litex.boards import can just be replaced with litex_boards:

from litex.boards.platforms import kc705

from litex_boards.platforms import kc705
