477 * (the PC before the pmove statement points to the virtual address of
478 * the code). Getting that physical address is not hard, but the code
479 * becomes a bit complex since I've tried to ensure that the jump
480 * statement after the pmove is in the cache already (otherwise the
481 * processor can't fetch it!). For that, the code first jumps to the
482 * jump statement with the (virtual) address of the pmove section in
483 * an address register . The jump statement is surely in the cache
484 * now. After that, that physical address of the reset code is loaded
485 * into the same address register, pmove is done and the same jump
486 * statements goes to the reset code. Since there are not many
487 * statements between the two jumps, I hope it stays in the cache.
