cmake: restore canonical git.beafrancois.fr FetchContent URLs

cahute.beafrancois.fr is a host-local alias of one development PC; the canonical Gitea name is git.beafrancois.fr. Machines where that name does not resolve to the Gitea host can rewrite it locally with: git config --global url."ssh://gitea@<host>:8329/".insteadOf \ "ssh://gitea@git.beafrancois.fr:8329/"
cmake: point FetchContent at cahute.beafrancois.fr

+a standalone library, **[libbsdl](ssh://gitea@git.beafrancois.fr:8329/electronics/libbsdl.git)**
+(LGPL, seeded from the same Viveris loader), and is now pulled in via
+CMake `FetchContent` instead of vendored. The SVF player core moved the
+same way into **[libsvf](ssh://gitea@git.beafrancois.fr:8329/electronics/libsvf.git)**
+(shared with the `wifi_jtag_programmer` Zephyr firmware, which plays SVF
+through an embedded JTAG port); `src/modules/svf/` is now only the
+bscan-backed glue. To build against local checkouts (side-by-side dev):
+configure with `-DFETCHCONTENT_SOURCE_DIR_BSDL=/path/to/libbsdl` and/or
+`-DFETCHCONTENT_SOURCE_DIR_SVF=/path/to/libsvf`.

François	f47295b94b	cmake: restore canonical git.beafrancois.fr FetchContent URLs cahute.beafrancois.fr is a host-local alias of one development PC; the canonical Gitea name is git.beafrancois.fr. Machines where that name does not resolve to the Gitea host can rewrite it locally with: git config --global url."ssh://gitea@<host>:8329/".insteadOf \ "ssh://gitea@git.beafrancois.fr:8329/"	2026-06-13 00:24:17 +02:00
François	8acc24eec7	cmake: point FetchContent at cahute.beafrancois.fr git.beafrancois.fr resolves to a host that no longer serves Gitea; all remotes already use cahute. Verified: a fresh configure clones libbsdl and libsvf and the full build succeeds with no local override.	2026-06-13 00:23:24 +02:00
François	831bd7c129	svf: extract player core into standalone libsvf, keep bscan glue The SVF player now lives in electronics/libsvf behind a five-function JTAG ops table, shared with the wifi_jtag_programmer Zephyr firmware. src/modules/svf/ shrinks to the bscan_*-backed port (bs_svf_play), which also keeps the FTDI stale-FIFO warm-up. Local checkout override: -DFETCHCONTENT_SOURCE_DIR_SVF=<path>.	2026-06-13 00:14:07 +02:00
François	2752c3404b	bsdl: extract parser into standalone libbsdl, pulled via FetchContent The BSDL loader (seeded from the Viveris parser) now lives in its own LGPL repo, electronics/libbsdl, consumed with CMake FetchContent. Local development override: -DFETCHCONTENT_SOURCE_DIR_BSDL=<path>. src/modules/bsdl_parser/ is removed; callers go through the libbsdl API. Build verified against the libbsdl checkout.	2026-06-13 00:10:02 +02:00
