#
# Hash descriptor database file consists of sections for various Chrome OS
# boards. Each board description section starts with a line of 4 characters
# which is the board ID (the same as the board's RLZ code).
#
# Each board description section includes variable number of range
# descriptor entries, each entry consisting of semicolon separated fields:
#
# {a|e|g}:{h|d}:base_addr:size[:value[:value[:value...]]]]
#
# Where
#
# - the first sindgle character field defines the way the range is accessed:
# a - AP flash
# e - EC flash
# g - EC flash requiring gang programming mode
# - the second single character field defines the range type
# h - Cr50 returns the hash of the range
# d - Cr50 returns actual contents of the range (hex dump)
# - the third and and forth fields are base address and size of the range
# - ranges of type 'h' include one or more values for the hash of the range.
#
# Descriptor entries can be split along multiple lines. Each entry is
# terminated by an empty line. Board description section is completed when
# another board ID or end of file is encountered.
#
# All values are expressed in hex. Repeating empty lines and lines starting
# with '#' are ignored.
