/* Bootloader to resume MIO A701
* 2007-1-12 Robert Jarzmik
* This code is licenced under the GPLv2.
#include <linux/linkage.h>
#include <asm/assembler.h>
* Note: Yes, part of the following code is located into the .data section.
* This is to allow jumpaddr to be accessed with a relative load
* while we can't rely on any MMU translation. We could have put
* sleep_save_sp in the .text section as well, but some setups might
* insist on it to be truly read-only.
