From 3d85f4a79fe2933c239125b55981cabcde897223 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 30 Sep 2012 11:43:13 +0000 Subject: [brcm47xx]: Fix reading sprom from nvram without a prefix The bcma based SoCs with a ieee80211 core on the SoC and an other connected via PCIe or USB store the sprom for the SoC with a sb/1/ prefix. The SoC with just one wifi core do not use prefixes. The BCM4706 do not use a prefix for the SoC part at all, because the prefix is the path to the ieee80211 core and there is non on the BCM4706. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@33597 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- ...193-MIPS-BCM47xx-read-out-full-board-data.patch | 81 ++++++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 target/linux/brcm47xx/patches-3.3/193-MIPS-BCM47xx-read-out-full-board-data.patch (limited to 'target/linux/brcm47xx/patches-3.3/193-MIPS-BCM47xx-read-out-full-board-data.patch') diff --git a/target/linux/brcm47xx/patches-3.3/193-MIPS-BCM47xx-read-out-full-board-data.patch b/target/linux/brcm47xx/patches-3.3/193-MIPS-BCM47xx-read-out-full-board-data.patch new file mode 100644 index 0000000000..bdfc348cc7 --- /dev/null +++ b/target/linux/brcm47xx/patches-3.3/193-MIPS-BCM47xx-read-out-full-board-data.patch @@ -0,0 +1,81 @@ +--- a/arch/mips/bcm47xx/sprom.c ++++ b/arch/mips/bcm47xx/sprom.c +@@ -164,10 +164,6 @@ static void nvram_read_alpha2(const char + static void bcm47xx_fill_sprom_r1234589(struct ssb_sprom *sprom, + const char *prefix) + { +- nvram_read_u16(prefix, NULL, "boardrev", &sprom->board_rev, 0); +- if (!sprom->board_rev) +- nvram_read_u16(NULL, NULL, "boardrev", &sprom->board_rev, 0); +- nvram_read_u16(prefix, NULL, "boardnum", &sprom->board_num, 0); + nvram_read_u8(prefix, NULL, "ledbh0", &sprom->gpio0, 0xff); + nvram_read_u8(prefix, NULL, "ledbh1", &sprom->gpio1, 0xff); + nvram_read_u8(prefix, NULL, "ledbh2", &sprom->gpio2, 0xff); +@@ -214,13 +210,6 @@ static void bcm47xx_fill_sprom_r2389(str + nvram_read_u8(prefix, NULL, "pa1himaxpwr", &sprom->maxpwr_ah, 0); + } + +-static void bcm47xx_fill_sprom_r2(struct ssb_sprom *sprom, const char *prefix) +-{ +- nvram_read_u32_2(prefix, "boardflags", &sprom->boardflags_lo, +- &sprom->boardflags_hi); +- nvram_read_u16(prefix, NULL, "boardtype", &sprom->board_type, 0); +-} +- + static void bcm47xx_fill_sprom_r389(struct ssb_sprom *sprom, const char *prefix) + { + nvram_read_u8(prefix, NULL, "bxa2g", &sprom->bxa2g, 0); +@@ -241,9 +230,6 @@ static void bcm47xx_fill_sprom_r389(stru + + static void bcm47xx_fill_sprom_r3(struct ssb_sprom *sprom, const char *prefix) + { +- nvram_read_u32_2(prefix, "boardflags", &sprom->boardflags_lo, +- &sprom->boardflags_hi); +- nvram_read_u16(prefix, NULL, "boardtype", &sprom->board_type, 0); + nvram_read_u8(prefix, NULL, "regrev", &sprom->regrev, 0); + nvram_read_leddc(prefix, "leddc", &sprom->leddc_on_time, + &sprom->leddc_off_time); +@@ -252,11 +238,6 @@ static void bcm47xx_fill_sprom_r3(struct + static void bcm47xx_fill_sprom_r4589(struct ssb_sprom *sprom, + const char *prefix) + { +- nvram_read_u32_2(prefix, "boardflags", &sprom->boardflags_lo, +- &sprom->boardflags_hi); +- nvram_read_u32_2(prefix, "boardflags2", &sprom->boardflags2_lo, +- &sprom->boardflags2_hi); +- nvram_read_u16(prefix, NULL, "boardtype", &sprom->board_type, 0); + nvram_read_u8(prefix, NULL, "regrev", &sprom->regrev, 0); + nvram_read_s8(prefix, NULL, "ag2", &sprom->antenna_gain.a2, 0); + nvram_read_s8(prefix, NULL, "ag3", &sprom->antenna_gain.a3, 0); +@@ -555,9 +536,23 @@ void bcm47xx_fill_sprom_ethernet(struct + nvram_read_macaddr(prefix, "il0macaddr", &sprom->il0mac); + } + ++static void bcm47xx_fill_board_data(struct ssb_sprom *sprom, const char *prefix) ++{ ++ nvram_read_u16(prefix, NULL, "boardrev", &sprom->board_rev, 0); ++ if (!sprom->board_rev) ++ nvram_read_u16(NULL, NULL, "boardrev", &sprom->board_rev, 0); ++ nvram_read_u16(prefix, NULL, "boardnum", &sprom->board_num, 0); ++ nvram_read_u16(prefix, NULL, "boardtype", &sprom->board_type, 0); ++ nvram_read_u32_2(prefix, "boardflags", &sprom->boardflags_lo, ++ &sprom->boardflags_hi); ++ nvram_read_u32_2(prefix, "boardflags2", &sprom->boardflags2_lo, ++ &sprom->boardflags2_hi); ++} ++ + void bcm47xx_fill_sprom(struct ssb_sprom *sprom, const char *prefix) + { + bcm47xx_fill_sprom_ethernet(sprom, prefix); ++ bcm47xx_fill_board_data(sprom, prefix); + + nvram_read_u8(prefix, NULL, "sromrev", &sprom->revision, 0); + +@@ -571,7 +566,6 @@ void bcm47xx_fill_sprom(struct ssb_sprom + bcm47xx_fill_sprom_r1234589(sprom, prefix); + bcm47xx_fill_sprom_r12389(sprom, prefix); + bcm47xx_fill_sprom_r2389(sprom, prefix); +- bcm47xx_fill_sprom_r2(sprom, prefix); + break; + case 3: + bcm47xx_fill_sprom_r1234589(sprom, prefix); -- cgit v1.2.3
