[PATCH 00/14] *** ARC port for review *** |

From: Cupertino Miranda <cmiranda@synopsys.com>
Hello everyone,
It is with utmost pleasure that on behalf of Synopsys I initiate the
upstream process for our ARCv2 architecture QEMU port.
I am one of the main contributors to this port and member of the
Synopsys GNU toolchain team, together with Claudiu Zissulescu and
Shahab Vahedi.
ARCv2 processors use RISC, and employ the 16-/32-bit instruction set
architecture (ISA).
ARC processors are configurable and extensible for a wide range of uses
in system on a chip (SoC) devices.
It is a common processor in deeply embedded systems, used in storage,
digital home, mobile, automotive, and Internet of Things (IoT)
applications.
To facilitate reviewing, we split the files through several commits,
attempting to keep file size to reviewable chunks.
The port as presented implements the system softmmu hardware emulation,
capable to boot and run Linux kernel.
It has also been integrated as a patch in Zephyr project, where it is
being used.
To validate and guarantee correctness of the port through development,
we have created TCG tests from the very beggining, covering the most
fundamental CPU features.
For the remaining instructions we validate the port through compiler
testsuites, like DejaGNU, comparing results with real hardware
executions.
Would like also to thank our colleagues Vineet Gupta and Alexey Broadkin
for their contributions, which due to the collapse of the development
commits, got their contributions overcast by major ones.

Looking forward to your comments and suggestions.
Best regards,
Cupertino Miranda
