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...
