[PATCH 0/2] xtensa: add GDBIO implementation to semihosting interface

[Max Filippov]

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.
