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 |
|
|
|---|---|---|---|---|
|
|
| `SER5` | `ser5/` | amd64 | UEFI firmware, removable-media path | GPT + FAT32 ESP: `EFI/BOOT/BOOTX64.EFI` |
|
|
| `RASPI` | `raspi/` | aarch64 | Pi 5 EEPROM firmware, native | MBR + FAT32: `config.txt`, `kernel_2712.img`, `bcm2712-rpi-5-b.dtb` |
|
|
| `MILKV` | `milkv/` | riscv64 | SPI-flash U-Boot + OpenSBI, `bootefi` | GPT + FAT32 ESP: `EFI/BOOT/BOOTRISCV64.EFI` |
|
|
| `ZYNQ7020` | `zynq7020/` | armv7 | BootROM, `BOOT.BIN`, U-Boot | not yet: needs `kernel/src/arch/armv7` |
|
|
|
|
`board.mk` sets:
|
|
|
|
- `BOARD_DESC`: one-line description (`make boards`)
|
|
- `BOARD_ARCH`: kernel ISA (`kernel/src/arch/<arch>`)
|
|
- `BOARD_BOOT`: image recipe in `kernel/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.
