Subject: [PATCH 0/2] xtensa: add GDBIO implementation to semihosting interface
Date: Fri, 26 Mar 2021 12:31:41 -0700 [thread overview]
Message-ID: <20210326193143.21016-1-jcmvbkbc@gmail.com> (raw)
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.
