openocd: src/target: replace the GPL-2.0-or-later license tag Replace the FSF 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.

basic ARM semihosting support Semihosting enables code running on an ARM target to use the I/O facilities on the host computer. The target application must be linked against a library that forwards operation requests by using the SVC instruction that is trapped at the Supervisor Call vector by the debugger. The "hosted" library version provided with CodeSourcery's Sourcery G++ Lite for ARM EABI is one example. This is currently available for ARM9 processors, but any ARM variant should be able to support this with little additional work. Tested using binaries compiled with Sourcery G++ Lite 2009q1-161 and ARM RVCT 3.0.

Rework/update ARM semihosting In 2016, ARM released the second edition of the semihosting specs ("Semihosting for AArch32 and AArch64"), adding support for 64-bits. To ease the reuse of the semihosting logic for other platforms (like RISC-V), the semihosting code was isolated from the ARM target and updated to the latest specs. The new code is already in use since January (in GNU MCU Eclipse OpenOCD) and no problems were reported, neither for ARM nor for RISC-V targets, after more than 7K downloads. The 2 new files were formatted with uncrustify.

semihosting: support fileio operation This patch adds support for bridging semihosting to GDB's File-I/O remote protocol extension. For the most part operations match up 1:1, however some require a working area to complete successfully, namely operations that devolve to read, stat, and gettimeofday. A new command was added to enable support for fileio named `arm semihosting_fileio`, which ensures that the default behavior remains intact for those that prefer it. Finally, redundant logging was removed from the target_arch_state function; this permits ARM targets to quiesce log output when polling for a fileio reply. This prevents filling the logs with halt/resume messages when using semihosting fileio.
