114 *
115 * This code emulates TT SCSI DMA on the Hades.
116 *
117 * Note the following:
118 *
119 * 1. When there is no byte available to read from the SCSI bus, or
120 * when a byte cannot yet bet written to the SCSI bus, a bus
121 * error occurs when reading or writing the pseudo DMA data
122 * register (hades_psdm_reg). We have to catch this bus error
123 * and try again to read or write the byte. If after several tries
124 * we still get a bus error, the interrupt handler is left. When
125 * the byte can be read or written, the interrupt handler is
126 * called again.
127 *
128 * 2. The SCSI interrupt must be disabled in this interrupt handler.
129 *
130 * 3. If we set the EOP signal, the SCSI controller still expects one
131 * byte to be read or written. Therefore the last byte is transferred
132 * separately, after setting the EOP signal.
133 *
134 * 4. When this function is left, the address pointer (start_addr) is
135 * converted to a physical address. Because it points one byte
136 * further than the last transferred byte, it can point outside the
137 * current page. If virt_to_phys() is called with this address we
138 * might get an access error. Therefore virt_to_phys() is called with
139 * start_addr - 1 if the count has reached zero. The result is
140 * increased with one.
