* While it would be legal to substitute a different hash operation
* entirely, let's keep it simple and just use an optimized multiply
* by GOLDEN_RATIO_32 = 0x61C88647.
*
* The best way to do that appears to be to multiply by 0x8647 with
* shifts and adds, and use mulu.w to multiply the high half by 0x61C8.
*
* Because the 68000 has multi-cycle shifts, this addition chain is
* chosen to minimise the shift distances.
*
* Despite every attempt to spoon-feed it simple operations, GCC
* 6.1.1 doggedly insists on doing annoying things like converting
* "lsl.l #2,<reg>" (12 cycles) to two adds (8+8 cycles).
*
* It also likes to notice two shifts in a row, like "a = x << 2" and
* "a <<= 7", and convert that to "a = x << 9". But shifts longer
* than 8 bits are extra-slow on m68k, so that's a lose.
*
* Since the 68000 is a very simple in-order processor with no
* instruction scheduling effects on execution time, we can safely
* take it out of GCC's hands and write one big asm() block.
*
* Without calling overhead, this operation is 30 bytes (14 instructions
* plus one immediate constant) and 166 cycles.
*
* (Because %2 is fetched twice, it can't be postincrement, and thus it
* can't be a fully general "g" or "m". Register is preferred, but
* offsettable memory or immediate will work.)

* Apple Peripheral System Controller (PSC)

* configured, and then you flip the active member and start all over again.
* The one-shot channels are grouped together and are:

* 3. Ethernet Write
* 4. Floppy Disk Controller
* 5. SCC Channel A Receive
* 6. SCC Channel B Receive
* 7. SCC Channel A Transmit

* The remaining two channels are handled somewhat differently. They appear
* to be closely tied and share one set of registers. They also seem to run
* continuously, although how you keep the buffer filled in this scenario is
* not understood as there seems to be only one input and one output buffer
* pointer.
*
* Much of this was extrapolated from what was known about the Ethernet
* registers and subsequently confirmed using MacsBug (ie by pinging the
* machine with easy-to-find patterns and looking for them in the DMA
