By the way, `Much more changes` came from the following message which
was commented on [PATCH v3 0/3] Add support for WDIOF_CARDRESET on TI
AM65x:


One thing I keep wondering about: What prevents the Linux kernel from
treating the special memory area like normal memory ? I would have
expected
some usage note, such as that the memory area must be reported as
reserved
to the kernel, but I don't see anything like that.
