- The API changes name from `_SWITCH_APP` to `_SYSTEM_MODE_CTRL`.
- The registers and wires changes name to `system_mode_*`, instead of a
mix of `switch_app_*` and `fw_app_mode`.
production_test related files are moved out of this repository, since it
relates to production of the hardware and not the fpga construction or
firmware.
* -abc2, run two passes of 'abc' for slightly improved logic density
* -device u, optimize timing for up5k device
* -dff, run 'abc'/'abc9' with -dff (D flip flop) option
Update digest of application_fpga.bin
Flags:
--indentation_spaces=2
--wrap_end_else_clauses=true
Verify flag, used in checkfmt, only returns error if the last file is
not formatted, temporary fix implemented with grep.
To simplify versioning and isolate the different parts of the projects
to their own repositories, these hardware parts are moved to separate
locations.
- tk1, mta1-usb-dev, mta-usb-v1 and mta1-library moves to
https://github.com/tillitis/tk1-pcba
- tp1, mta1-usb-programmer, mta1-library and KiCad-RP Pico moves to
https://github.com/tillitis/tp1
- Relevant documentation referring to these boards are also moved to the
new repositories, links are updated to point to the new location
- The CERN-OHL-S license is removed from this repo
- CI is no longer building the TP1 firmware
* Break long lines and use tab to indent
* Remove use of "tee" since it messes up the return status
* Remove the generated application_fpga_par.json if nextpnr-ice40 fails
on timing.
* Change log file ending from .log to .txt
* Fix some spacing
The removal is coordinated and approved by YosysHQ, and are removed
to keep our headers uniform. These files were written on behalf of
Tillitis.
Two typos was corrected as well.
- Remove the define `NOCONSOLE`, add define `QEMU_CONSOLE`
- Inverse the use of it, add the define to have QEMU debug output in fw.
- Add a make target `qemu_firmware.elf` which builds the firmware with
QEMU console enabled.

Move the logic implementing the RAM address and data
scrambling, descrambling into the RAM module. This cleans up
the top level, and makes it easier to change the scrambling
without chaning the top. In order to do correct scrambling the
address to the RAM core must be 16 bits, not 15.
Clean up some minor details at the top level, fixing text
aligment and grouping of ports in instances.

Add API address to trigger system reset.
When written to will send system_reset signal
to the reset generator, which then perform a complete
reset cycle of the FPGA system.
