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>

/* Linker script for the Raspberry Pi 5 native (non-UEFI) kernel image.
|
|
*
|
|
* Linked from the same objects as the aarch64 kernel ELF, entered at
|
|
* rpi5_native_start (arch/aarch64/native_rpi5_entry.S, section
|
|
* .text.entry -- placed first so it sits at the load address), then
|
|
* flattened with `objcopy -O binary` into kernel_2712.img.
|
|
*
|
|
* Load address 0x80000 must match boards/raspi/config.txt's
|
|
* kernel_address=0x80000: Pi 5 firmware's own default for
|
|
* kernel_2712.img is 0x200000, so the address is pinned on both sides
|
|
* rather than left to the firmware default.
|
|
*
|
|
* __kernel_start/__kernel_end span the whole image including .bss so
|
|
* pmm_init() reserves every page the image occupies (aarch64 boot.S's
|
|
* zero-length substitutes are only correct for the UEFI loader path,
|
|
* where UEFI owns the image pages). __bss_start/__bss_end are 16-byte
|
|
* aligned for the entry stub's zeroing loop: firmware does not clear
|
|
* memory past the end of the file it loads.
