- * Useful bootup functions, which are more easily done in asm than C.
- *
- * NOTE:  Be very very careful about the registers you use here.
- *	We don't follow any ABI calling convention among the
- *	assembler functions that call each other, especially early
- *	in the initialization.  Please preserve at least r3 and r4
- *	for these early functions, as they often contain information
- *	passed from boot roms into the C decompress function.
