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
openocd: src: fix incorrect SPDX tags The SPDX tag is aimed at machine handling and it's thus expected to be placed in the first line in specific format. Move the SPDX tag to the first line and fix it where needed. 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.

jtag: use proper format with uint32_t Modify the format strings to properly handle uint32_t data types. Change the prototype of detect_swo_freq_and_prescaler() in 'jlink.c' to avoid an implicit cast in the caller function. Change the type of the variable retlen in some functions in 'usb_blaster.c' to properly pass their pointer to the local read and write functions. Use the proper parser COMMAND_PARSE_NUMBER(u32, ...).

jtag: drivers: xlnx-pcie-xvc: Add support for SWD mode. Add support for SWD debug to the Xilinx XVC/PCIe driver. This is possible since the device is essentially a shift-register. So doing SWD vs JTAG is a matter of wiring things correctly on the RTL side (use TMS for SWDI, TDO for SWDO). The clang static checker doesn't find any new problems with this change.

jtag: drivers: xlnx-pcie-xvc: fix build after merge Commit [1] was submitted in gerrit well before the conflicting commit [2] get merged in master branch. While it was fine committing in master branch [1] alone, it should not be committed "as is" after [2]. Unfortunately gerrit did not complained committing [1] after [2]. The result is that master branch does not build anymore when the driver xlnx-pcie-xvc is enabled at configure time by the optional flag --enable-xlnx-pcie-xvc. Apply to the driver the required changes as in [2]. While there, remove the duplicated struct xlnx_pcie_xvc_transports and the struct field already implicitly initialized to zero.

jtag: drivers: xlnx-pcie-xvc: Add support for Xilinx XVC/PCIe Add support for Xilinx Virtual Cable over PCIe JTAG controller. It is commonly used in Xilinx based PCI Express designs with JTAG IP in the FPGA fabric. Access to the JTAG registers happens via the PCI Express extended configuration space. This can be used to debug soft-cores instantiated in the FPGA fabric. The clang static checker doesn't find any new problems with this change.
