Currently save_boot_params saves the boot parameters passed from romcode. But this is not stored in a writable location consistently. So the current code would not work for a 'XIP' boot. Change this by saving the boot parameters in 'gd' which is always writable. Also add a 'C' function instead of an assembly code that is more readable. Signed-off-by: Sricharan R <r.sricharan@ti.com>
