/* ++roman:

*
|
|
* This function does a reset on machines that lack the ability to
|
|
* assert the processor's _RESET signal somehow via hardware. It is
|
|
* based on the fact that you can find the initial SP and PC values
|
|
* after a reset at physical addresses 0 and 4. This works pretty well
|
|
* 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
|
|
* than GCC!
