The xlnx_pcie_xvc_execute_stableclocks() function can and
should be static.

24db985f60 jtag: avoid checking for non NULL pointer to free it
The function free() can be called with a NULL pointer as argument,
no need to check the argument before. If the pointer is NULL, no
operation is performed by free().

Remove the occurrences of pattern:
	if (ptr)
		free(ptr);

2f62883161 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, ...).

64733434e2 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.

d91e19eb16 jtag: drivers: xlnx-pcie-xvc: fix build on Linux pre v4.10
The macro PCI_CFG_SPACE_EXP_SIZE is exposed to userspace from
Linux kernel v4.10, with commit cc10385b6fde ("PCI: Move config
space size macros to pci_regs.h")
http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cc10385b6fde

Define the macro in the driver code, if not already defined.

60aaf14837 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.

[1] ff6d0704ec ("jtag: drivers: xlnx-pcie-xvc: Add support for
    Xilinx XVC/PCIe")
[2] efd1d64222 ("adapter: switch from struct jtag_interface to
    adapter_driver")

ff6d0704ec 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.
