Hi,

what would be the right place in modern pata driver to implement the
following old code from function do_probe() in ide-probe.c ?

/*
 *  ColdFire platforms boot up so quick that most hard drives
 *  have not completed there own self tests. Pause here for
 *  a couple of seconds if it looks like there is a drive
 *  present...
 */
if (IN_BYTE(IDE_SELECT_REG) != drive->select.all) {
  printk("IDE: waiting for drives to settle...\n");
  for (rc = 0; (rc < 400); rc++) {
    SELECT_DRIVE(hwif,drive);
    ide_delay_50ms();
    if (IN_BYTE(IDE_SELECT_REG) == drive->select.all)
     break;
 }
}

It has to be executed once, so placing it into command handler is
probably not the right solution.

Have you verified this is needed, under libata?  We already have several 
waits...

Unfortunately it is needed. It is embedded system, where bootloader
always tries to boot from the first device (dvd-rom). Second device
(hard disk) is not yet ready when kernel is loaded from flash and does
probe.

I placed the code into dev_select callback

void jasper_dev_select(struct ata_port *ap, unsigned int device)
{
        u8 tmp;
        if (device == 0)
                tmp = ATA_DEVICE_OBS;
        else
                tmp = ATA_DEVICE_OBS | ATA_DEV1;
        iowrite8(tmp, ap->ioaddr.device_addr);
        ata_pause(ap);          /* needed; also flushes, for mmio */
        if (device && firstSlaveAccess) {
                firstSlaveAccess = 0;
                printk("waiting for drive to settle...\n");
                if (ioread8(ap->ioaddr.device_addr) != tmp) {
                        int rc;
                        for (rc = 0; rc < 150; rc++) {
                                iowrite8(tmp, ap->ioaddr.device_addr);
                                mdelay(50); //ata_pause(ap);
                                if (ioread8(ap->ioaddr.device_addr) == tmp)
                                        break;
                        }
                }
        }
}

It takes about 30 cycles (1.5s) to select slave for the first time.

Can you show us the dmesg (printk) output from libata, _without_ 
dev_select or other "wait for drive to settle" special code?

Turn on ATA_DEBUG and ATA_VERBOSE_DEBUG in include/linux/libata.h before 
generating this output, please.

Thanks,

	Jeff

Boot log without special code but with ATA_DEBUG and ATA_VERBOSE_DEBUG
turned on is attached. Here is also a quote from a boot log with
