davinci: remove obsolete macro CONFIG_EMAC_MDIO_PHY_NUM fb1d6332b5430b90a8fa8ebab709f33a60e9f816 I get following warning on the enbw_cmc board: Err: serial Net: 5 ETH PHY detected miiphy_register: non unique device name 'KSZ8873 @ 0x01' DaVinci-EMAC Hit any key to stop autoboot: 0 Also I see some debug printfs: => run load + emac_close + emac_ch_teardown - emac_ch_teardown + emac_ch_teardown - emac_ch_teardown - emac_close + emac_open - emac_open Using DaVinci-EMAC device reason is 062fe7d332c28ede25626f448681e43d76bb312e new define MAX_PHY. This is set to 3! I get on this board 5 active phys, so this leads in wrong memory writes ... so I changed: - MAX_PHY from 3 to 7 - print an error message if more then MAX_PHYs are detected. - fill the active_phy_addr array in a for loop with 0xff - changed printf() in debug_emac() Signed-off-by: Heiko Schocher <h...@denx.de> Cc: Sandeep Paulraj <s-paul...@ti.com> Cc: Albert ARIBAUD <albert.u.b...@aribaud.net> Cc: Wolfgang Denk <w...@denx.de> Cc: Manjunath Hadli <manjunath.ha...@ti.com> --- drivers/net/davinci_emac.c | 17 +++++++++++------ 1 files changed, 11 insertions(+), 6 deletions(-) diff --git a/drivers/net/davinci_emac.c b/drivers/net/davinci_emac.c index fa31159..a31e9f1 100644 --- a/drivers/net/davinci_emac.c +++ b/drivers/net/davinci_emac.c @@ -85,7 +85,7 @@ static int emac_rx_queue_active = 0; /* Receive packet buffers */ static unsigned char emac_rx_buffers[EMAC_MAX_RX_BUFFERS * (EMAC_MAX_ETHERNET_PKT_SIZE + EMAC_PKT_ALIGN)]; -#define MAX_PHY 3 +#define MAX_PHY 7 /* PHY address for a discovered PHY (0xff - not found) */ static u_int8_t active_phy_addr[MAX_PHY] = { 0xff, 0xff, 0xff }; @@ -160,9 +160,8 @@ static int davinci_eth_phy_detect(void) int j; unsigned int count = 0; - active_phy_addr[0] = 0xff; - active_phy_addr[1] = 0xff; - active_phy_addr[2] = 0xff; + for (i = 0; i < MAX_PHY; i++) + active_phy_addr[i] = 0xff; udelay(1000); phy_act_state = readl(&adap_mdio->ALIVE); @@ -175,7 +174,13 @@ static int davinci_eth_phy_detect(void) for (i = 0, j = 0; i < 32; i++) if (phy_act_state & (1 << i)) { count++; - active_phy_addr[j++] = i; + if (count < MAX_PHY) + active_phy_addr[j++] = i; + else { + printf("%s: to much PHYs detected.\n", + __func__); + break; + } } num_phy = count; @@ -752,7 +757,7 @@ int davinci_emac_initialize(void) if (!ret) return(0); else - printf(" %d ETH PHY detected\n", ret); + debug_emac(" %d ETH PHY detected\n", ret); /* Get PHY ID and initialize phy_ops for a detected PHY */ for (i = 0; i < num_phy; i++) { -- 1.7.6.4 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
