- *
- * This code emulates TT SCSI DMA on the Hades.
- *
- * Note the following:
- *
- * 1. When there is no byte available to read from the SCSI bus, or
- * when a byte cannot yet bet written to the SCSI bus, a bus
- * error occurs when reading or writing the pseudo DMA data
- * register (hades_psdm_reg). We have to catch this bus error
- * and try again to read or write the byte. If after several tries
- * we still get a bus error, the interrupt handler is left. When
- * the byte can be read or written, the interrupt handler is
- * called again.
- *
- * 2. The SCSI interrupt must be disabled in this interrupt handler.
- *
- * 3. If we set the EOP signal, the SCSI controller still expects one
- * byte to be read or written. Therefore the last byte is transferred
- * separately, after setting the EOP signal.
- *
- * 4. When this function is left, the address pointer (start_addr) is
- * converted to a physical address. Because it points one byte
- * further than the last transferred byte, it can point outside the
- * current page. If virt_to_phys() is called with this address we
- * might get an access error. Therefore virt_to_phys() is called with
- * start_addr - 1 if the count has reached zero. The result is
- * increased with one.
