* The following routine can be used here if booting from internal
* Flash and it is desired to changed the FLASHBAR from the reset
* value of 0x0000_0000 to something else (defined as ___FLASH in
* a linker file for this example).
*
* To accomplish this, the following instructions are coded into
* the internal SRAM and then executed from there:
*
* move.l #(___FLASH + 0x61),d0
* movec d0, FLASHBAR
* jmp _asm_startmeup
*
* This sequence must be executed from a non-Flash address since we
* are changing the location of Flash. All the code in Flash should
* be linked to run from the desired Flash address even though the
* initial FLASHBAR is going to be 0x0000_0000.
*
* If this routine is to be used, uncomment it and comment out the
* jmp to _asm_startmeup above.
