From cf8f985dfcea8bc0e0728645f643d6c8f71792b7 Mon Sep 17 00:00:00 2001 From: hauke Date: Sat, 16 Feb 2013 20:28:24 +0000 Subject: brcm47xx: add initial support for kernel 3.8 This contains the following new bigger changes: * new partition parser which still could lake some features or have bugs * new nand flash driver * using physmap-flash flash driver for parallel flash * some changes to the serial flash driver With these changes OpenWrt starts using more of the mainline flash drivers. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35632 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../brcm47xx/patches-3.8/760-bgmac-fixes.patch | 190 +++++++++++++++++++++ 1 file changed, 190 insertions(+) create mode 100644 target/linux/brcm47xx/patches-3.8/760-bgmac-fixes.patch (limited to 'target/linux/brcm47xx/patches-3.8/760-bgmac-fixes.patch') diff --git a/target/linux/brcm47xx/patches-3.8/760-bgmac-fixes.patch b/target/linux/brcm47xx/patches-3.8/760-bgmac-fixes.patch new file mode 100644 index 000000000..d764806cf --- /dev/null +++ b/target/linux/brcm47xx/patches-3.8/760-bgmac-fixes.patch @@ -0,0 +1,190 @@ +--- a/drivers/net/ethernet/broadcom/bgmac.c ++++ b/drivers/net/ethernet/broadcom/bgmac.c +@@ -301,7 +301,7 @@ static int bgmac_dma_rx_read(struct bgma + bgmac_err(bgmac, "Found poisoned packet at slot %d, DMA issue!\n", + ring->start);
