# Edit History
# 201406xx: WestfW: More Makefile restructuring.
#                   Split off Makefile.1284, Makefile.extras, Makefile.custom
#                   So that in theory, the main Makefile contains only the
#                   official platforms, and does not need to be modified to
#                   add "less supported" chips and boards.
# 201303xx: WestfW: Major Makefile restructuring.
#                   Allows options on Make command line "make xx LED=B3"
#                   (see also pin_defs.h)
#                   Divide into "chip" targets and "board" targets.
#                   Most boards are (recursive) board targets with options.
#                   Move isp target to separate makefile (fixes m8 EFUSE)
#                   Some (many) targets will now be rebuilt when not
#                     strictly necessary, so that options will be included.
#                     (any "make" with options will always compile.)
#                   Set many variables with ?= so they can be overridden
#                   Use arduinoISP settings as default for ISP targets

#---------------------------------------------------------------------------
# "Chip-level Platform" targets.
# A "Chip-level Platform" compiles for a particular chip, but probably does
# not have "standard" values for things like clock speed, LED pin, etc.
# Makes for chip-level platforms should usually explicitly define their
# options like: "make atmega1285 AVR_FREQ=16000000L LED=D0"
#---------------------------------------------------------------------------
#
# Note about fuses:
# the efuse should really be 0xf8; since, however, only the lower
# three bits of that byte are used on the atmega168, avrdude gets
# confused if you specify 1's for the higher bits, see:
# http://tinker.it/now/2007/02/24/the-tale-of-avrdude-atmega168-and-extended-bits-fuses/
#
# similarly, the lock bits should be 0xff instead of 0x3f (to
# unlock the bootloader section) and 0xcf instead of 0x2f (to
# lock it), but since the high two bits of the lock byte are
# unused, avrdude would get confused.
