Thomas Hebb 7ac389cf47 tcl/target/gd32vf103: work around broken ndmreset
On this chip, the ndmreset bit in the RISC-V debug module doesn't
trigger a system reset like it should. To work around this, add a custom
"reset-assert" handler in its config file that resets the system by
writing to memory-mapped registers.

I've tested this workaround on a Sipeed Longan Nano dev board with a
GD32VF103CBT6 chip. It works correctly for both "reset run" and "reset
halt" (halting at pc=0 for the latter).

I originally submitted[1] this workaround to the riscv-openocd fork of
OpenOCD. That fork's maintainers accepted it, but have not upstreamed it
like they have several other of my changes.

Antonio Borneo e6505b0489 tcl/target: 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/ 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.

The flash is compatible with stm32f1x, reuse the driver.

Extend the size of work area to RAM size of the smallest device.

Stop watchdogs before flash programming.
