Todor Minchev ac83d7c726 rmc-db: allow multiple fingerprint per board directory
Different firmware revisions often result in different fingerprints for
the same hardware platform. This change allows multiple fingerprints to
be stored in the same board directory to avoid having to duplicate the
data for each record.

# 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.
