469 * after a reset at physical addresses 0 and 4. This works pretty well
470 * for Atari machines, since the lowest 8 bytes of physical memory are
471 * really ROM (mapped by hardware). For other 680x0 machines: don't
472 * know if it works...
473 *
474 * To get the values at addresses 0 and 4, the MMU better is turned
475 * off first. After that, we have to jump into physical address space
476 * (the PC before the pmove statement points to the virtual address of
477 * the code). Getting that physical address is not hard, but the code
478 * becomes a bit complex since I've tried to ensure that the jump
479 * statement after the pmove is in the cache already (otherwise the
480 * processor can't fetch it!). For that, the code first jumps to the
481 * jump statement with the (virtual) address of the pmove section in
482 * an address register . The jump statement is surely in the cache
483 * now. After that, that physical address of the reset code is loaded
484 * into the same address register, pmove is done and the same jump
485 * statements goes to the reset code. Since there are not many
486 * statements between the two jumps, I hope it stays in the cache.
487 *
488 * The C code makes heavy use of the GCC features that you can get the
