#
# Targetname Architecture CPU Boardname Vendor SoC
# each entry has the fields documented below.

# Unused fields can be specified as "-", or omitted if they

# Blank lines are ignored.

# The options field takes the form:
# <board config name>[:comma separated config options]
# Each config option has the form (value defaults to "1"):
# option[=value]
# So if you have:
# FOO:HAS_BAR,BAZ=64
# The file include/configs/FOO.h will be used, and these defines created:
# #define CONFIG_HAS_BAR 1
# #define CONFIG_BAZ 64
#
# To keep the list sorted, use something like
#
# :.,$! sort -f -k2,2 -k3,3 -k6,6 -k5,5 -k1,1
