Separate the two concerns the repo root was mixing:
- src/ — bs/, modules/, libs/ (code + vendored libs)
- data/ — fpga_registry.yaml, probes.yaml, bsdl_files/, bscan_proxies/,
scripts/ (everything the tool reads at runtime, CWD-relative)
- doc/ — kept at the root
CMake: repoint DIR_MODULES/DIR_LIBS and add_subdirectory at src/; emit
the binary at the build/ root (build/bs) via CMAKE_RUNTIME_OUTPUT_DIRECTORY
instead of the nested build/src/bs/. The jtag_core ../../libs path still
resolves since modules and libs moved together.
Runtime default paths now point under data/ (fpga.c, probes.c, script.c
bsdl_files lookup, init.c config.script). Docs (README/tutorial/CLAUDE)
updated for the new layout, src/ module paths, and ./build/bs.
Validated on the IGLOO2/FlashPro: profiles, autoinit, and svf_play all
work run from the repo root.

BSCAN proxy bitstreams
Pre-built "BSCAN proxy" bitstreams that bridge the JTAG USER1
instruction to an FPGA's SPI flash pins (via a BSCANE2 primitive),
enabling fast SPI flashing — see doc/tutorial.md, Phase 2.5.
These .bit files are not built here. They come from
quartiq/bscan_spi_bitstreams,
© QUARTIQ GmbH, MIT-licensed — see LICENSE.quartiq. The host-side
framing in src/modules/bscan/ matches OpenOCD's jtagspi so the same
bitstreams work.

To add another part, drop the matching bscan_spi_<part>.bit here and
point the registry entry's proxy_bitstream field at it.
