 465 * This function does a reset on machines that lack the ability to
 466 * assert the processor's _RESET signal somehow via hardware. It is
 467 * based on the fact that you can find the initial SP and PC values
 468 * after a reset at physical addresses 0 and 4. This works pretty well
 469 * for Atari machines, since the lowest 8 bytes of physical memory are
 470 * really ROM (mapped by hardware). For other 680x0 machines: don't
 471 * know if it works...
 472 *
 473 * To get the values at addresses 0 and 4, the MMU better is turned
 474 * off first. After that, we have to jump into physical address space
 475 * (the PC before the pmove statement points to the virtual address of
 476 * the code). Getting that physical address is not hard, but the code
 477 * becomes a bit complex since I've tried to ensure that the jump
 478 * statement after the pmove is in the cache already (otherwise the
 479 * processor can't fetch it!). For that, the code first jumps to the
 480 * jump statement with the (virtual) address of the pmove section in
 481 * an address register . The jump statement is surely in the cache
 482 * now. After that, that physical address of the reset code is loaded
 483 * into the same address register, pmove is done and the same jump
 484 * statements goes to the reset code. Since there are not many
 485 * statements between the two jumps, I hope it stays in the cache.
 486 *
 487 * The C code makes heavy use of the GCC features that you can get the
 488 * address of a C label. No hope to compile this with another compiler
 489 * than GCC!
