For historical reasons, no license information was added to the
tcl files. This makes trivial adding the SPDX tag through script:
fgrep -rL SPDX tcl/ target| while read a;do \
sed -i '1{i# SPDX-License-Identifier: GPL-2.0-or-later\n
}' $a;done
With no specific license information from the author, let's extend
the OpenOCD project license GPL-2.0-or-later to the files.

# according to errata, we need to use vectreset rather than sysresetreq to avoid lockup
|
|
# There is a bug in the chip, which means that when using external debuggers the chip
|
|
# may lock up in certain CPU clock modes. Affected modes are operating the CPU at
|
|
# 24MHz derived from the 24MHz crystal, or 12MHz derived from the high frequency RC
|
|
# oscillator. If an external debugger tool asserts SYSRESETREQ, the chip will lock up and
|
|
# require a pin reset or power cycle.
