# This file is included by ../$(ARCH)/Makefile.
# It defines the rules needed to build the boot blocks and
# standalone programs.
#
# Certain symbols must be defined before this header file may be included:
#	$(ARCH)		target kernel architecture (e.g., sun2, sun4c)
#	$(ARCHOPTS)	CFLAGS specific to target kernel architecture
#	$(ARCHOBJ)	list of arch-dependent object files for libboot.a
#	$(ARCHLIBS)	list of arch-dependent object libraries
#	$(MACHDIR)	directory in which to find Makefile.mach (eg, ../m68k)
#	$(BOOTBLOCKS)	list of machine-dependent targets
#
# All targets are built in ../$(ARCH)

#ALL is now defined in each architecture's Makefile
