From 318c9e430b7381f99c0746209a428a3e0008b9fd Mon Sep 17 00:00:00 2001 From: hauke Date: Sat, 13 Jun 2009 21:20:53 +0000 Subject: [brcm47xx] Port to kernel 2.6.30. There is an error in the unlzma system in the kernel. A lzma compressed squashfs filesystem does not work for me. This should compile and works for me on my Asus WL-500GP, please test it on more systems. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@16441 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../700-ssb-gigabit-ethernet-driver.patch | 336 +++++++++++++++++++++ 1 file changed, 336 insertions(+) create mode 100644 target/linux/brcm47xx/patches-2.6.30/700-ssb-gigabit-ethernet-driver.patch (limited to 'target/linux/brcm47xx/patches-2.6.30/700-ssb-gigabit-ethernet-driver.patch') diff --git a/target/linux/brcm47xx/patches-2.6.30/700-ssb-gigabit-ethernet-driver.patch b/target/linux/brcm47xx/patches-2.6.30/700-ssb-gigabit-ethernet-driver.patch new file mode 100644 index 0000000000..a524dff5d2 --- /dev/null +++ b/target/linux/brcm47xx/patches-2.6.30/700-ssb-gigabit-ethernet-driver.patch @@ -0,0 +1,336 @@ +--- a/drivers/net/tg3.c ++++ b/drivers/net/tg3.c +@@ -41,6 +41,7 @@ + #include + #include + #include ++#include + + #include + #include +@@ -446,8 +447,9 @@ static void _tw32_flush(struct tg3 *tp, + static inline void tw32_mailbox_flush(struct tg3 *tp, u32 off, u32 val) + { + tp->write32_mbox(tp, off, val); +- if (!(tp->tg3_flags & TG3_FLAG_MBOX_WRITE_REORDER) && +- !(tp->tg3_flags2 & TG3_FLG2_ICH_WORKAROUND)) ++ if ((tp->tg3_flags3 & TG3_FLG3_FLUSH_POSTED_WRITES) || ++ (!(tp->tg3_flags & TG3_FLAG_MBOX_WRITE_REORDER) && ++ !(tp->tg3_flags2 & TG3_FLG2_ICH_WORKAROUND))) + tp->read32_mbox(tp, off); + } + +@@ -457,7 +459,7 @@ static void tg3_write32_tx_mbox(struct t + writel(val, mbox); + if (tp->tg3_flags & TG3_FLAG_TXD_MBOX_HWBUG) + writel(val, mbox); +- if (tp->tg3_flags & TG3_FLAG_MBOX_WRITE_REORDER) ++ if ((tp->tg3_flags & TG3_FLAG_MBOX_WRITE_REORDER) || (tp->tg3_flags3 & TG3_FLG3_FLUSH_POSTED_WRITES)) + readl(mbox); + } + +@@ -729,7 +731,7 @@ static void tg3_switch_clocks(struct tg3 + + #define PHY_BUSY_LOOPS 5000 + +-static int tg3_readphy(struct tg3 *tp, int reg, u32 *val) ++static int __tg3_readphy(struct tg3 *tp, unsigned int phy_addr, int reg, u32 *val) + { + u32 frame_val; + unsigned int loops; +@@ -743,7 +745,7 @@ static int tg3_readphy(struct tg3 *tp, i + + *val = 0x0; + +- frame_val = ((PHY_ADDR << MI_COM_PHY_ADDR_SHIFT) & ++ frame_val = ((phy_addr << MI_COM_PHY_ADDR_SHIFT) & + MI_COM_PHY_ADDR_MASK); + frame_val |= ((reg << MI_COM_REG_ADDR_SHIFT) & + MI_COM_REG_ADDR_MASK); +@@ -778,7 +780,12 @@ static int tg3_readphy(struct tg3 *tp, i + return ret; + } + +-static int tg3_writephy(struct tg3 *tp, int reg, u32 val) ++static int tg3_readphy(struct tg3 *tp, int reg, u32 *val) ++{ ++ return __tg3_readphy(tp, PHY_ADDR, reg, val); ++} ++ ++static int __tg3_writephy(struct tg3 *tp, unsigned int phy_addr, int reg, u32 val) + { + u32 frame_val; + unsigned int loops; +@@ -794,7 +801,7 @@ static int tg3_writephy(struct tg3 *tp, + udelay(80); + } + +- frame_val = ((PHY_ADDR << MI_COM_PHY_ADDR_SHIFT) & ++ frame_val = ((phy_addr << MI_COM_PHY_ADDR_SHIFT) & + MI_COM_PHY_ADDR_MASK); + frame_val |= ((reg << MI_COM_REG_ADDR_SHIFT) & + MI_COM_REG_ADDR_MASK); +@@ -827,6 +834,11 @@ static int tg3_writephy(struct tg3 *tp, + return ret; + } + ++static int tg3_writephy(struct tg3 *tp, int reg, u32 val) ++{ ++ return __tg3_writephy(tp, PHY_ADDR, reg, val); ++} ++ + static int tg3_bmcr_reset(struct tg3 *tp) + { + u32 phy_control; +@@ -2262,6 +2274,9 @@ static int tg3_nvram_read(struct tg3 *tp + { + int ret; + ++ if (tp->tg3_flags3 & TG3_FLG3_IS_SSB_CORE) ++ return -ENODEV; ++ + if (!(tp->tg3_flags & TG3_FLAG_NVRAM)) + return tg3_nvram_read_using_eeprom(tp, offset, val); + +@@ -2595,8 +2610,10 @@ static int tg3_set_power_state(struct tg + tg3_frob_aux_power(tp); + + /* Workaround for unstable PLL clock */ +- if ((GET_CHIP_REV(tp->pci_chip_rev_id) == CHIPREV_5750_AX) || +- (GET_CHIP_REV(tp->pci_chip_rev_id) == CHIPREV_5750_BX)) { ++ if ((tp->phy_id & PHY_ID_MASK != PHY_ID_BCM5750_2) && ++ /* !!!
