Claude 3bd81097e1 chore(license): an SPDX header on every source file that had none (LicenseRef-Starship-1.0) [skip ci]
The header scan (Captain Bob, 2026-11-10): 788 source files -- 351 with the
SL-1.0 header, 12 with the old name (docs/working/experiments, kept by
ruling), 31 under someone else's licence (tools/kconfig, Linux's, GPL-2.0:
kept), and 394 with none. Ruled: the SPDX form; capsules (.4th, .f18) and
proofs (.thy) left for a ruling of their own (mkcapsule's 64x16 block format,
content-addressed capsules).

as a /* */ block (C, headers, assembly, linker scripts) or # lines (scripts,
Makefiles, Kconfig; below a shebang or a coding line); tools/mkcapsule.c,
which had the copyright line, gets the SPDX line only.

Not touched: docs/working/ (archive and old campaign material, as the
ruling kept the experiments); v4/system/post_cases.c (generated by
v4/tools/mkpost.py, "do not edit" -- the generator has the header).

Comments only: the kernel builds on amd64, aarch64, riscv64; make -C v4
test-32: 39 programs, 0 failures; every changed script parses.

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
PC pc/ amd64 UEFI firmware, removable-media path -- any x86-64 PC 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 PC image has been booted in QEMU (q35 + OVMF, from its own disk) through POST. (PC was named SER5 until 2026-10-14, after the first PC on the bench; the image was never specific to it.) The Pi 5 native path (raspi/README.md) and the JH7110 peripherals have still only been checked by compiling.
