Subject[RFC Patch v1 00/31] Synopsys ARC Linux kernel Port
Date
Hi,

This patchset based off-of 3.7-rc3, introduces the Linux kernel port to
ARC700 processor family (750D and 770D) from Synopsys.

ARC700 is highly configurable and power efficient 32-bit RISC core with MMU.
It is embedded in SoCs deployed in TV Set Top boxes, Digital Media Players,
all the way to Network-on-Chips.

More information is available @
http://www.synopsys.com/IP/ProcessorIP/ARCProcessors/Pages/default.aspx

This series is part #1 of the entire port - just enough to build the kernel
and bring up a Busybox shell on console (on ARCAngel4 FPGA ref platform)
The console driver has already been accepted/merged into tty-next tree for 3.8

The part #2 series containing additional features ptrace/SMP/perf/OProfile..
will follow as we move along the review cycle. It has been withheld just to
make it easier for reviewers.

The entire series however is available at
git://github.com/foss-for-synopsys-dwc-arc-processors/linux.git arc-3.7-rc3

The GNU tool-chain, based off of gcc 4.4 + uClibc 0.9.30.3 is also available
from github. Please refer to Readme.md in "toolchain" repository also in same
hierarchy as kernel above.

We are already working on a buildroot based distro, to be made available soon.

More info about the kernel port can also be found in the ELCE-Barclone '12
talk on same topic.

https://raw.github.com/vineetgarc/publish/master/ELCE-2012-ARC-Linux.pdf

All comments/criticisms are welcome !

P.S. Despite 3.7 based, we are still short of the UAPI split for arch headers.
That is also being worked upon with help from David. That will show up in v2
of the patchseries.

Thx,
-Vineet
