From d6cc73e4e70a7f8712c52ef9d93a19a906cc3d4b Mon Sep 17 00:00:00 2001 From: Markus Klotzbuecher Date: Wed, 12 Jul 2006 09:08:36 +0200 Subject: Bugfix in FEC initialisation: All MII configuration is done via FEC1 registers. But MII_SPEED was configured according to FEC used. So if only FEC2 was used, this caused the real MII_SPEED register in FEC1 to stay uninitalised, what lead to "mii_send STUCK!" messages. Fix: always configure MII_SPEED on FEC1 only. --- cpu/mpc8xx/fec.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'cpu/mpc8xx') diff --git a/cpu/mpc8xx/fec.c b/cpu/mpc8xx/fec.c index 21c9070..9ebee59 100644 --- a/cpu/mpc8xx/fec.c +++ b/cpu/mpc8xx/fec.c @@ -396,8 +396,10 @@ static void fec_pin_init(int fecidx) * * to 2.5 MHz. * * This MDC frequency is equal to system clock / (2 * MII_SPEED). * * Then MII_SPEED = system_clock / 2 * 2,5 Mhz. + * + * All MII configuration is done via FEC1 registers: */ - fecp->fec_mii_speed = ((bd->bi_intfreq + 4999999) / 5000000) << 1; + immr->im_cpm.cp_fec1.fec_mii_speed = ((bd->bi_intfreq + 4999999) / 5000000) << 1; #if defined(CONFIG_NETTA) || defined(CONFIG_NETPHONE) || defined(CONFIG_NETTA2) /* our PHYs are the limit at 2.5 MHz */ -- cgit v1.1
