Add support for the Renesas MFIS mailbox, which provides an interface
between the different CPU Cores, such as AP System Core domain and the
Realtime Core domain, SCP Core domain and AP System Core domain or
Realtime Core domain and AP System Core domain or Realtime Core domain.

Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> # Update the driver
[Marek: Rename the driver to renesas-mfis, simplify the driver.
Always use only one TX channel and no RX channel, drop all
unnecessary code. Perform 1ms delay in send callback which
is perfectly fine to do in U-Boot which does RX polling]

help
|
|
Enable support for the mailbox driver class. Mailboxes provide the
|
|
ability to transfer small messages and/or notifications from one
|
|
CPU to another CPU, or sometimes to dedicated HW modules. They form
|
|
the basis of a variety of inter-process/inter-CPU communication
|
|
protocols.

such as the System Management Controller (SMC) and NVMe and this
|
|
driver is required to get that functionality up and running.
