From: Rod Whitby Date: Fri, 29 Jun 2007 06:30:32 +0000 (+0000) Subject: Added support for the D-Link DSM-G600 RevA, and fixed the clock frequency for NSLU2... X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5efd069ecb6780cda5a7f47cbdf980d3ada3c94c;p=openwrt%2Fstaging%2Fneocturne.git Added support for the D-Link DSM-G600 RevA, and fixed the clock frequency for NSLU2 and DSMG600. Had to refresh the gateway 7001 patch due to changes in the file being patched.
