# There are two usages of the baseboard name that we want to change, using
# the Hatch baseboard and the Kohaku variant in this example.
# ---
# That one is easy; replace all-uppercase of the baseboard with all-uppercase
# of the variant. The second one is
# CONFIG_IFD_BIN_PATH="3rdparty/blobs/baseboard/hatch/descriptor-hatch.bin"
# ---
# CONFIG_IFD_BIN_PATH="3rdparty/blobs/baseboard/hatch/descriptor-kohaku.bin"
# The "hatch" name occurs twice in the original path, and we only want to
# change the last occurrence, so we get 'descriptor-kohaku.bin'.
# Another possibility for the IFD is that the baseboard doesn't use a
# hyphenated name, so we also need to search for descriptor.bin, e.g.
# CONFIG_IFD_BIN_PATH="3rdparty/blobs/baseboard-octopus/descriptor.bin"
