# This is a quick-hack until the Linux version of FIXCODE.C is finished.
# Note that it does not search for the AiR-BOOT Protection Signature,
# but embeds it at the 'well known' location.
# If the protection image is moved, this script will produce a corrupted
# AIRBOOT.BIN.
# Also, a code-size of 35h (max size) is always inserted.
# Furthermore, it does not do any sanity checks whatsoever.

# This script is now obsolete.
