- * Misc. bootloader code for many machines. This assumes you have are using
- * a 6xx/7xx/74xx CPU in your machine. This assumes the chunk of memory
- * below 8MB is free. Finally, it assumes you have a NS16550-style uart for
- * your serial console. If a machine meets these requirements, it can quite
- * likely use this code during boot.
