makefile

一个很好的嵌入式linux平台下的bootloader

#
# This is just a Makefile fragment -- it is included by the master
# makefile, cfe.mk
#
# This file should just append object file names to "ALLOBJS",
# but since it is mean to be linked *first*, it will append
# modules to "CRT0OBJS"
#
#
#  Macro               Contains
#  CRT0OBJS            Files that must be linked first for CFE
#  ALLOBJS             Other files for CFE
#  ZCRTO0OBJS          Files that must be linked first for ZIPSTART
#  ZSOBJS              ZIPSTART object files
#

#
# Allow makefile to override init_mips.S.  If not overridden, it's
# either 'init_mips.S' or 'init_ram.o' for RAMAPP and ZIPSTART versions.
#
