joyride-1563 broken, olpc.fth missing, fails to boot [FIX]

[Mitch Bradley]

You don't really need the entire olpc.fth - the following lines should 
suffice:

ok setenv ramdisk n:\boot\olpcrd.img
ok boot n:\boot\vmlinuz root=mtd0 rootfstype=jffs2

Those lines are short enough to type manually.

The rest of olpc.fth is just automated reflash and support for boot-alt.
Most of the cmdline arguments (ro, console=, fbcon=) are unnecessary - 
the only required ones are the root specifiers.
