[PATCH 0/4] Introducing the Alpine platform.

[Tsahee Zidenberg]

Annapurna Labs(TM) is a technology company providing innovative solutions
including chips, software, and systems for the datacenter and enterprise
infrastructure.

Alpine(TM) is one of Annapurna Labs? chip products targeting storage and
networking applications. It is a complete Platform-On-Chip,
integrating 2-4 cortex-A15 cores and multiple innovations to provide
a seamless networking and storage fabric for enterprise and datacenter
equipment.

This patchset provides initial support for the Alpine platform.

Patch #1 contains minimal, single-cpu architecture support.

Patch #2 adds early-debug capabilities via Alpine UART 0.

Patch #3 adds smp-support and a secondary cpu enable-method for the platform.

Patch #4 provides a device-tree for quad-core Alpine, along with documentation
for the available device-tree nodes.

The patchset was built on Linux 3.19-rc3,
tested with multi_v7_defconfig, adding CONFIG_ARCH_ALPINE

Looks very nice overall!

I've replied with some specific comments, but if you address them
quickly, this might still make it into 3.20.

Do you have a public git tree with the other device drivers and
bindings you will need on top of this?

Thank you! We are very excited about sending these patches. An update
patchset will be sent soon.

No public git tree yet.

A complete kernel supporting alpine platform is available in
accordance with GPL for a few products.
E.g. this from synology:
http://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/5004branch/synogpl-5004-alpine.tbz/download

Thank you!
