Subject: [PATCH] brcm63xx: add initial support for Netgear EVG2000
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This patch adds support for the Netgear EVG2000 VoIP Gateway to the
bcm63xx targets.

This device was not sold to the general public, but rather is/was
provided by telcos to customers in Sweden, Australia, Singapore and
other parts of asia.

Known issues:
 - Unable to detect 53115 switch. This appear to be a problem with
probing for the PHY using MDIO and results in error 5. Doesn't seem to
be a problem with the configuration, and could use someone with
experience to have a look at it.
 - Uses the b43 driver as using the OpenWRT/LEDE broadcom-wl driver
fails to load the firmware for the 4322, so 802.11n is not supported.

More info on the device and the research can be found at:
