-** linux/arch/m68k/boot/amiga/bootstrap.c -- This program loads the Linux/m68k
-**					     kernel into an Amiga and launches
-**					     it.

-** Modified 11-May-94 by Geert Uytterhoeven
-**			(Geert.Uytterhoeven@cs.kuleuven.ac.be)
-**     - A3640 MapROM check
-** Modified 31-May-94 by Geert Uytterhoeven
-**     - Memory thrash problem solved
-** Modified 07-March-95 by Geert Uytterhoeven
-**     - Memory block sizes are rounded to a multiple of 256K instead of 1M
-**	 This _requires_ >0.9pl5 to work!
-**	 (unless all block sizes are multiples of 1M :-)
-** Modified 11-July-95 by Andreas Schwab
-**     - Support for ELF kernel (untested!)
-** Modified 10-Jan-96 by Geert Uytterhoeven
-**     - The real Linux/m68k boot code moved to linuxboot.[ch]
-** Modified 9-Sep-96 by Geert Uytterhoeven
-**     - Rewritten option parsing
-**     - New parameter passing to linuxboot() (linuxboot_args)
-** Modified 6-Oct-96 by Geert Uytterhoeven
-**     - Updated for the new boot information structure
