remote_bitbang: Add SWD support This adds new command characters to make SWD work with the new split jtag and swd operations of bitbang. The command characters are as follows: O - SWDIO drive 1 o - SWDIO drive 0 c - SWDIO read request d - SWD write 0 0 e - SWD write 0 1 f - SWD write 1 0 g - SWD write 1 1 Documentation has been updated accordingly. The new commands will be used by an adapted version of the jtag-openocd applet of the "Glasgow Debug Tool" (https://github.com/glasgowEmbedded/Glasgow). It has been tested against an stm32f103 and an at91samd21 target. contrib/remote/bitbang/remote_bitbang_sysfsgpio.c has also been adapted to support SWD via the new command set. Some limited testing has been done using a Raspberry Pi 2 with an stm32f103 and an at91samd21 target attached.

openocd: fix SPDX tag format for files .c With the old checkpatch we cannot use the correct format for the SPDX tags in the file .c, in fact the C99 comments are not allowed and we had to use the block comment. With the new checkpatch, let's switch to the correct SPDX format. Change created automatically through the command: sed -i \ 's,^/\* *\(SPDX-License-Identifier: .*[^ ]\) *\*/$,// \1,' \ $(find src/ contrib/ -name \*.c) Change-Id: I6da16506baa7af718947562505dd49606d124171 Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com> Reviewed-on: https://review.openocd.org/c/openocd/+/7153 Tested-by: jenkins
contrib: replace the GPLv2-or-later license tag Replace the GPLv2-or-later boilerplate with the SPDX tag. The SPDX tag on files *.c is incorrect, as it should use the C99 single line comment using '//'. But current checkpatch doesn't allow C99 comments, so keep using standard C comments, by now.

drivers/remote_bitbang: Group adapter commands Use a command group 'remote_bitbang' with subcommands instead of individual commands with 'remote_bitbang_' prefix. The old commands are still available for backward compatibility but marked as deprecated.

Move xsvf_tools and remote_bitbang to contrib/ It looks like tools/ should be used only for build tools, and contrib/ is a suitable place for everything else.
