Subject: [PATCH] network driver for Hilscher netx
Date: Thu, 22 Jun 2006 07:11:13 +0200 [thread overview]
Message-ID: <20060622051113.GC6831@localhost.localdomain> (raw)
This is a patch for the Hilscher netx builtin ethernet ports. The
netx board support was merged into 2.6.17-git2.
The netx is a arm926 based SoC.
