- * Support for broken devices :
- * The Seagate board has a handshaking problem. Namely, a lack
- * thereof for slow devices. You can blast 600K/second through
- * it if you are polling for each byte, more if you do a blind
- * transfer. In the first case, with a fast device, REQ will
- * transition high-low or high-low-high before your loop restarts
- * and you'll have no problems. In the second case, the board
- * will insert wait states for up to 13.2 usecs for REQ to
- * transition low->high, and everything will work.
- *
- * However, there's nothing in the state machine that says
- * you *HAVE* to see a high-low-high set of transitions before
- * sending the next byte, and slow things like the Trantor CD ROMS
- * will break because of this.
- *
- * So, we need to slow things down, which isn't as simple as it
- * seems. We can't slow things down period, because then people
- * who don't recompile their kernels will shoot me for ruining
- * their performance. We need to do it on a case per case basis.
- *
- * The best for performance will be to, only for borken devices
- * (this is stored on a per-target basis in the scsi_devices array)
- *
- * Wait for a low->high transition before continuing with that
- * transfer. If we timeout, continue anyways. We don't need
- * a long timeout, because REQ should only be asserted until the
- * corresponding ACK is received and processed.
- *
- * Note that we can't use the system timer for this, because of
- * resolution, and we *really* can't use the timer chip since
- * gettimeofday() and the beeper routines use that. So,
- * the best thing for us to do will be to calibrate a timing
- * loop in the initialization code using the timer chip before
- * gettimeofday() can screw with it.
