# RMC database bbclass
# provide functions to generate RMC database file on build host (native)
DEPENDS += "rmc-native"
# rmc_generate_db()
# $1: a list of directories. Each directory holds directories for a group of
# boards.
# $2: path_name of rmc generates database file and records
#
# WARNING: content of directory of database file will be removed.
#
# Each board directory shall contain a fingerprint file (*.fp) at least, with
# optional file blob(s) associated to the type of board. If a board directory
# has no file blob, no record is created for that board.
#
# An example of two directories each of which contains two boards for RMC:
# (All file and directory names are for illustration purpose.)
#
# dir_1/
# board_1/
# board_1_fingerprint.fp
# file_1.blob
# board_2/
# board_2.fp
# dir_2/
# board_3/
# b3.fp
# file_1.blob
# file_2.conf
# board_4/
# board_foo.fp
# mylib.config
#
# To generate a RMC database "rmc.db" with data of all (actually 3) of boards in
# a directory "deploy_dir":
#
# rmc_generate_db "dir_1 dir_2" "deploy_dir/rmc.db"
#
# The board_2 will be skipped. No record or any data for it is packed in
# generated database because it only contains a fingerprint file.
