New subject: [LinuxBIOS] broadcom HT1000 SATA PHY initializing

Good.

Where to call it? Auto stage or called by hardwaremain driver?

Need to be effective after soft_reset?

Sata should be working with the following initializing code. (verified
on
two boards). Thanks!

Jianwei

void HT1000_SATA_init( void )
{
        volatile unsigned int *mmio_reg;
        unsigned int mmio_base,val32;
        int i;

        pcibios_write_config_byte( 1, HT1000_SATA, 0x70, 0x18);
        pcibios_write_config_byte( 1, HT1000_SATA, 0x78, 0x04);

        pcibios_read_config_dword (1, HT1000_SATA, 0x24, &mmio_base);

        mmio_base &= 0xfffffffc;

        mmio_reg = (unsigned int *)( mmio_base + 0x10f0 );

        * mmio_reg = 0x40000001;

        mmio_reg = ( unsigned int *)( mmio_base + 0x8c );
        * mmio_reg = 0x00ff2007;
        mdelay( 10 );
        * mmio_reg = 0x78592009;
        mdelay( 10 );
        * mmio_reg = 0x00082004;
        mdelay( 10 );
        * mmio_reg = 0x00002004;
        mdelay( 10 );

        for( i = 0; i < 4; i ++ )
        {
                mmio_reg = ( unsigned int *)( mmio_base + 0x40 + i * 256
);
                val32 = *mmio_reg ;
                if( val32 & 0x4 )
                {
                        mmio_reg = ( unsigned int *)( mmio_base + 0x48 +
i *
256);
                        val32 = *mmio_reg;
                        val32 |= 1;
                        *mmio_reg = val32;
                        mdelay( 10 );
                        val32 &= ( ~1 );
                        *mmio_reg = val32;
                        mdelay( 10 );
                }
        }

}

  You should be right.

 When I was testing that on Broadcom BLAST ref board: STAT and IDE
 doesn't work.

 But on another MB (serverworks HT1000 based), IDE is working.

 Maybe some magic bit in pci conf space need to set by option rom...

 You could compare the pci conf dump between system bios and LinuxBIOS...
...

 BTW, Can drop your funny signature in LinuxBIOS?
