Subject: [PATCH] ramips: rt305x: add kernel support for the Planex MZK-W300NH2
Router
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
This is a Japanese market router, for details check
http://www.planex.co.jp/product/router/mzk-w300nh2/. It has only 16MB
RAM, but base OpenWRT install worked fine for days without issues.
Even an image with built-in Luci worked, but don't expect smooth
experience, due to the lack of RAM. Wifi was not extensively tested,
but seems it is working. GPIO LEDs & buttons, factory flash image and
switch config are confirmed working. Tested against revision 34882 +
this patch.
[juhosg: move user-space support and image generation changes into
separate patches]
