boards/BRINGUP.md A6, FABRIC-3 SXLIII (ruled: one image, switch at boot). A STARFORTH_V4 kernel carries v3 too; system= in the boot arguments chooses, else the build's default (V4_DEFAULT: 1 for plain STARFORTH_V4 builds as before, 0 for board images). make boot_image builds both and always writes starforth.cfg / cmdline.txt with system=v3 first, and cleans its ISA's objects first -- that clean was removing build/<arch>/SER5, not the kernel's objects, until fixed here. Each ISA: v3 by default (hash unchanged), v4 with system=v4 (538/538). The SER5 image under OVMF: v3 as built, v4 after a one-word edit on it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# LithosAnanke / StarForth -- top-level Makefile

#
|
|
# Thin dispatcher. The real build lives in:
|
|
# v3/Makefile -- hosted StarForth v3 (Linux userland VM, POST, DoE)
|
|
# kernel/Makefile -- LithosAnanke kernel (UEFI loader, kernel ELF, QEMU)
|
|
# boards/<board>/ -- one directory per physical target (board.mk + boot files)
|
|
# docs/book/Makefile -- the single LaTeX book (build/docs/*.pdf)
|
|
# Every sub-make runs from this directory, so paths are always repo-relative.
|
|
#
|
|
# TARGET is either a board (SER5 RASPI MILKV ZYNQ7020), a hosted v3 profile
|
|
# (standard fast fastest turbo asan ...), or empty:
|

#
|
|
# make [all] every board that has a kernel port, the
|
|
# hosted v3 build, and the book
|
|
# make [all] TARGET=<board> that board's boot image + its book
|
|
# make [all] TARGET=<profile> hosted v3 build with that profile
|
|
#
|
|
# make boot_image TARGET=<board> only the board's boot image
|
