I enabled CONFIG_HIBERNATION, implemented 'swsusp_arch_suspend'
which saves some general registers (%g,%i,%o,%l) and call
'swsusp_save', and 'swsusp_arch_resume' which load 'pblist' and
restore those registers.
Now my T2 can create hibernation images, but after restore the image,
it crashes. If there's something I missed?
Thanks!
