From 374bb82f67f49829cb443fe95a11d88c83675be4 Mon Sep 17 00:00:00 2001 From: hauke Date: Sun, 1 May 2011 20:28:35 +0000 Subject: brcm47xx: add fallback sprom for pci devices without an own sprom. If there is no sprom on an ssb based pci device on the brcm47xx architecture ssb now asks the architecture code to look into the nvram to get some sprom data for this device. Now we are able to read out pci/1/1/ foo or pci/1/3/ foo config options. This will fix some problems where the wireless devices does not got an mac address and the following message was show: ssb: WARNING: Invalid SPROM CRC (corrupt SPROM) git-svn-id: svn://svn.openwrt.org/openwrt/trunk@26801 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../033-bcm47xx-register-fallback-callback.patch | 48 ++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 target/linux/brcm47xx/patches-2.6.38/033-bcm47xx-register-fallback-callback.patch (limited to 'target/linux/brcm47xx/patches-2.6.38/033-bcm47xx-register-fallback-callback.patch') diff --git a/target/linux/brcm47xx/patches-2.6.38/033-bcm47xx-register-fallback-callback.patch b/target/linux/brcm47xx/patches-2.6.38/033-bcm47xx-register-fallback-callback.patch new file mode 100644 index 0000000000..f63deacddf --- /dev/null +++ b/target/linux/brcm47xx/patches-2.6.38/033-bcm47xx-register-fallback-callback.patch @@ -0,0 +1,48 @@ +--- a/arch/mips/bcm47xx/nvram.c ++++ b/arch/mips/bcm47xx/nvram.c +@@ -23,7 +23,7 @@ + static char nvram_buf[NVRAM_SPACE]; + + /* Probe for NVRAM header */ +-static void __init early_nvram_init(void) ++static void early_nvram_init(void) + { + struct ssb_mipscore *mcore = &ssb_bcm47xx.mipscore; + struct nvram_header *header; +--- a/arch/mips/bcm47xx/setup.c ++++ b/arch/mips/bcm47xx/setup.c +@@ -156,6 +156,22 @@ static void bcm47xx_fill_sprom(struct ss + } + } + ++int bcm47xx_get_sprom(struct ssb_bus *bus) ++{ ++ char prefix[10]; ++ ++ if (bus->bustype == SSB_BUSTYPE_PCI) { ++ snprintf(prefix, sizeof(prefix), "pci/%x/%x/", ++ bus->host_pci->bus->number + 1, ++ PCI_SLOT(bus->host_pci->devfn)); ++ bcm47xx_fill_sprom(&bus->sprom, prefix); ++ return 0; ++ } else { ++ printk(KERN_WARNING "bcm47xx: unable to fill SPROM for given bustype.\n"); ++ return -EINVAL; ++ } ++} ++ + static int bcm47xx_get_invariants(struct ssb_bus *bus, + struct ssb_init_invariants *iv) + { +@@ -212,6 +228,11 @@ void __init plat_mem_setup(void) + char buf[100]; + struct ssb_mipscore *mcore; + ++ err = ssb_arch_register_fallback_sprom(&bcm47xx_get_sprom); ++ if (err) ++ printk(KERN_WARNING "bcm47xx: someone else already registered" ++ " a ssb SPROM callback handler (err %d)\n", err); ++ + err = ssb_bus_ssbbus_register(&ssb_bcm47xx, SSB_ENUM_BASE, + bcm47xx_get_invariants); + if (err) -- cgit v1.2.3
