From 7152b1d0b3f8beec8c297d64664e41b4c4ef610a Mon Sep 17 00:00:00 2001 From: wdenk Date: Fri, 5 Sep 2003 23:19:14 +0000 Subject: * Add support for SK98xx driver * Add PCI support for SL8245 board * Support IceCube board configurations with 1 x AMD AM29LV065 (8 MB) or 1 x AM29LV652 (two LV065 in one chip = 16 MB); Run IPB at 133 Mhz; adjust the MII clock frequency accordingly * Set BRG_CLK on PM825/826 to 64MHz (VCO_OUT / 4, instead of 16 MHz) to allow for more accurate baudrate settings (error now 0.7% at 115 kbps, instead of 3.5% before) * Patch by Andreas Mohr, 4 Sep 2003: Fix a lot of spelling errors --- cpu/mpc5xxx/cpu_init.c | 16 ++++++++-------- cpu/mpc5xxx/fec.c | 5 +++-- 2 files changed, 11 insertions(+), 10 deletions(-) (limited to 'cpu/mpc5xxx') diff --git a/cpu/mpc5xxx/cpu_init.c b/cpu/mpc5xxx/cpu_init.c index cec5c2bc67..a93a198cf5 100644 --- a/cpu/mpc5xxx/cpu_init.c +++ b/cpu/mpc5xxx/cpu_init.c @@ -24,14 +24,6 @@ #include #include -#if defined(CONFIG_MGT5100) -#define START_REG(start) ((start) >> 15) -#define STOP_REG(start, size) (((start) + (size) - 1) >> 15) -#elif defined(CONFIG_MPC5200) -#define START_REG(start) ((start) >> 16) -#define STOP_REG(start, size) (((start) + (size) - 1) >> 16) -#endif - /* * Breath some life into the CPU... * @@ -159,6 +151,14 @@ void cpu_init_f (void) #if defined(CONFIG_MPC5200) /* enable timebase */ *(vu_long *)(MPC5XXX_XLBARB + 0x40) |= (1 << 13); + + /* Motorola reports IPB should better run at 133 MHz. */ + *(vu_long *)MPC5XXX_ADDECR |= 1; + /* pci_clk_sel = 0x02, ipb_clk_sel = 0x00; */ + addecr = *(vu_long *)MPC5XXX_CDM_CFG; + addecr &= ~0x103; + addecr |= 0x02; + *(vu_long *)MPC5XXX_CDM_CFG = addecr; #endif } diff --git a/cpu/mpc5xxx/fec.c b/cpu/mpc5xxx/fec.c index 557355f9d2..06dd56fc50 100644 --- a/cpu/mpc5xxx/fec.c +++ b/cpu/mpc5xxx/fec.c @@ -208,6 +208,7 @@ static void mpc5xxx_fec_set_hwaddr(mpc5xxx_fec_priv *fec, char *mac) /********************************************************************/ static int mpc5xxx_fec_init(struct eth_device *dev, bd_t * bis) { + DECLARE_GLOBAL_DATA_PTR; mpc5xxx_fec_priv *fec = (mpc5xxx_fec_priv *)dev->priv; struct mpc5xxx_sdma *sdma = (struct mpc5xxx_sdma *)MPC5XXX_SDMA; const uint8 phyAddr = 0; /* Only one PHY */ @@ -269,10 +270,10 @@ static int mpc5xxx_fec_init(struct eth_device *dev, bd_t * bis) fec->eth->x_cntrl = 0x00000004; /* full-duplex, heartbeat disabled */ /* - * Set MII_SPEED = (1/(mii_speed * 2)) * System Clock(25Mhz) + * Set MII_SPEED = (1/(mii_speed * 2)) * System Clock * and do not drop the Preamble. */ - fec->eth->mii_speed = (0x5 << 1); /* No MII for 7-wire mode */ + fec->eth->mii_speed = (((gd->ipb_clk >> 20) / 5) << 1); /* No MII for 7-wire mode */ } /* -- cgit v1.2.3
