Source tree reorganization: - Move StarForth v3 engine to v3/ (src/, include/, Makefile) - Move kernel to kernel/ (src/, include/, linker/, Makefile) - Create v4/ skeleton for F18-ISA golden model (DECOMPOSITION.md, JUSTIFICATION.md) - Move FABRIC-0..4.md to docs/fabric/ - Move ONTOLOGY.md and ROADMAP.md to docs/ Board infrastructure: - Add boards/ser5/, boards/raspi/, boards/milkv/, boards/zynq7020/ - Each board has board.mk (ISA, CPU flags, boot recipe) and README.md - Root Makefile becomes thin dispatcher: boot_image, all, clean, docs take TARGET - make boot_image TARGET=SER5|RASPI|MILKV builds one GPT/MBR image per board - ZYNQ7020 target exists but stops with clear error (ARMv7 port not built yet) - scripts/mkdiskimage.sh builds disk images for all boards Docs pipeline: - docs/book/ with LaTeX master (main.tex) and Makefile - pandoc converts Markdown to LaTeX at build time - Two Lua filters: table-widths.lua (wide tables wrap), code-breaks.lua (inline code breaks) - make docs builds single PDF (754 pages, 0 missing characters) - make docs TARGET=<board> adds board appendix - build/docs/<book|board>/meta.tex stamps git commit into PDF Bug fixes: - 42 include paths that only worked by accident now use correct relative paths - clang-18 hardcode replaced with configurable CC variable (fixed aarch64 build) - Pi 5: kernel_2712.img linked at 0x80000, .bss zeroed, memory reserved - Doxyfile, .clang-tidy, README.md, Kconfig paths updated Verified: - Hosted v3 build passes 1012 tests, 0 failures - SER5 image boots in QEMU (OVMF), POST passes, K exact (65536 = Q48_ONE) - Milk-V image boots in QEMU (OpenSBI + U-Boot + bootefi), POST passes - make clean TARGET=<board> removes only that board and its ISA objects - make all builds all boards, hosted v3, and docs in one run Co-authored-by: Junie <junie@jetbrains.com>
boards/
One directory per physical target. make boot_image TARGET=<NAME> (repo root) maps the
name to a directory here, reads its board.mk, and builds the single file that goes on
that board's boot medium into build/boards/<board>/.
| TARGET | Directory | ISA | Boot path | Image |

board.mk sets:
BOARD_DESC: one-line description (make boards)BOARD_ARCH: kernel ISA (kernel/src/arch/<arch>)BOARD_BOOT: image recipe inkernel/Makefile(uefi-esp,rpi-native, ...)BOARD_IMAGE: output file name
Disk images are assembled by scripts/mkdiskimage.sh, which needs no root access and no loop
devices. KERNEL_ARGS="..." is written as starforth.cfg (UEFI boards) or cmdline.txt
(Pi 5, where the firmware copies it into /chosen/bootargs). BOOT_IMAGE_SIZE_MIB sets the
image size; the default is 128.
Hardware status: none of these images has been booted on real silicon from this build. The
SER5 image has been booted in QEMU (q35 + OVMF, from its own disk) through POST. The Pi 5
native path (raspi/README.md) and the JH7110 peripherals have still only been checked by
compiling.
