Ok thanks.

Could you please document in the patch how the WkupM3 memory is
managed? Perhaps add to this latter explanation of yours also what
stands behind the umem/dmem names, justify usage of '__force' and
document the code around the l4_offset math (which I suspect may not
always be correct, as it seems the value of l4_offset depends on the
order of mem resources returned by platform_get_resource_byname).

Thanks,
Ohad.
