Add a mailbox driver framework/uclass A mailbox is a hardware mechanism for transferring small message and/or notifications between the CPU on which U-Boot runs and some other device such as an auxilliary CPU running firmware or a hardware module. This patch defines a standard API that connects mailbox clients to mailbox providers (drivers). Initially, DT is the only supported method for connecting the two. The DT binding specification (mailbox.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.

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.
mailbox: implement a sandbox test This adds a sandbox mailbox implementation (provider), a test client device, instantiates them both from Sandbox's DT, and adds a DM test that excercises everything. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org> # v1

help
Enable support for a test mailbox implementation, which simply echos
back a modified version of any message that is sent.
