2018-12-12esirisc: support eSi-TraceSteven Stallion
This patch adds support for instruction tracing to eSi-RISC targets. The command interface is borrowed heavily from ETM; eSi-Trace uses a less sophisticated model for tracing, however the setup and usage is similar. This patch also cleans up the command interfaces of the other esirisc command groups and adds additional debugging information to log messages when dealing with CSRs. This patch "finalizes" support for 32-bit eSi-RISC targets.

2018-10-16esirisc: support eSi-RISC targetsSteven Stallion
eSi-RISC is a highly configurable microprocessor architecture for embedded systems provided by EnSilica. This patch adds support for 32-bit targets and also includes an internal flash driver and uC/OS-III RTOS support. This is a non-traditional target and required a number of additional changes to support non-linear register numbers and the 'p' packet in RTOS support for proper integration into EnSilica's GDB port.
