Hello, this series adds GDBIO implementation to the semihosting interface and makes it a configuration time choice. GDBIO interface is useful for development hardware platforms that don't offer any peripherals and only accessible via JTAG. xtensa kernel built for ISS may be run on such platforms using GDBIO implementation of the semihosting interface.
