tcl: add SPDX tag 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 | 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.

cpld: altera-epm240: Increase adapter speed According to the datasheet, the minimum clock period with Vccio1 = 1.5V (the lowest voltage supported) is 143ns, or around 6MHz. Set the default adapter speed to 5 MHz.

# 200ns seems like a good speed
# c.f. Table 5-34: MAX II JTAG Timing Parameters
adapter speed 5000
