Re: [LinuxBIOS] broadcom HT1000 SATA PHY initializing

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 );
                }
        }

}
