# this is a collection of support procs for the target data
# structures. We use a named array, since Tcl has no real data
# structures. Here's the special index words for the array:
# Required fields are:
# name - the name of the target. (mostly for error messages) This
# should also be the string used for this target's array.
# It should also be the same as the linker script so we
# can find them dynamically.
# Optional fields are:
# ldflags - the flags required to produce a fully linked executable.
# config - the target canonical for this target. This is a regexp
# as passed to istarget or isnative.
# cflags - the flags required to produce an object file from a
# source file.
# connect - the connectmode for this target. This is for both IP and
# serial connections.
# hostname - the hostname of the target. This is for TCP/IP based
# connections, and is also used for versions of tip that
# use /etc/remote.
# serial - the serial port. This is typically /dev/tty? or com?:.
# baud - the baud rate for a serial port connection.
# netport - the IP port.
# x10 - parameters for the x10 controller (used to reboot)
# fileid - the fileid or spawn id of of the connection.
# prompt - a regexp for matching the prompt.
# ioport - the port for I/O on dual port systems.
#
