From 36576137d6b9bcd959dab7d4545d14939dde6fbe Mon Sep 17 00:00:00 2001 From: rwhitby Date: Fri, 29 Jun 2007 06:30:32 +0000 Subject: 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. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@7770 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../ixp4xx-2.6/patches/070-ixp4xx_freq_fixup.patch | 131 +++++++++++++++++++++ 1 file changed, 131 insertions(+) create mode 100644 target/linux/ixp4xx-2.6/patches/070-ixp4xx_freq_fixup.patch (limited to 'target/linux/ixp4xx-2.6/patches/070-ixp4xx_freq_fixup.patch') diff --git a/target/linux/ixp4xx-2.6/patches/070-ixp4xx_freq_fixup.patch b/target/linux/ixp4xx-2.6/patches/070-ixp4xx_freq_fixup.patch new file mode 100644 index 000000000..5b406a7bc --- /dev/null +++ b/target/linux/ixp4xx-2.6/patches/070-ixp4xx_freq_fixup.patch @@ -0,0 +1,131 @@ +This patch is required as the frequency fixup in nslu2_init does not +run sufficiently early in the boot sequence to take effect.
