# PS4 Linux Baikal Kernel — Makefile
#
# All real work happens in build.sh. The Makefile is just convenience
# shortcuts. Pass TARGET= to switch (default: 6.18-baikal).
#
# Examples:
#   make                        # build default target (6.18-baikal)
#   make TARGET=6.x-baikal      # build archived 6.15 target
#   make clean TARGET=5.4-baikal
#   make patches-only TARGET=5.4-baikal

SHELL := /bin/bash
TARGET ?= 6.18-baikal
