# Forked by Travis Goodspeed <travis at tnbelt.com> for use with the GoodFET
# JTAG programmer.
+# This WIP is intended to save the info flash when using --fromweb.
+# DONE:
+# - Save info flash before actionMassErase
+# - Make actionFromweb use board name to get the right firmware image
+# - Program saved info after other programming is complete
+# - Make saveinfo detect missing info (all 0xFF)
+# TODO:
+# - Trim unnecessary BSL unlocks
+# - Download image from web before erasing
+# - Add param to override saveinfo with a provided info.txt
+# - Figure out better way to saveinfo when -P is required
+# - Maybe use the best guess from contrib/infos/ when nothing better is provided?
+# - If saveinfo gets something interesting, request a copy
+# - Use FTDI Serial Number to archive info text and/or password (dragorn's idea)
+# /sys/bus/usb-serial/devices/ttyUSB0/../../serial
