* This function does a reset on machines that lack the ability to

* for Atari machines, since the lowest 8 bytes of physical memory are
* really ROM (mapped by hardware). For other 680x0 machines: don't
* know if it works...
*
* To get the values at addresses 0 and 4, the MMU better is turned
* off first. After that, we have to jump into physical address space
* (the PC before the pmove statement points to the virtual address of
* the code). Getting that physical address is not hard, but the code
* becomes a bit complex since I've tried to ensure that the jump
* statement after the pmove is in the cache already (otherwise the
* processor can't fetch it!). For that, the code first jumps to the
* jump statement with the (virtual) address of the pmove section in
* an address register . The jump statement is surely in the cache
* now. After that, that physical address of the reset code is loaded
* into the same address register, pmove is done and the same jump
* statements goes to the reset code. Since there are not many
* statements between the two jumps, I hope it stays in the cache.
*
* The C code makes heavy use of the GCC features that you can get the
* address of a C label. No hope to compile this with another compiler
