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.

menu "Mailbox Controller Support"
config DM_MAILBOX
bool "Enable mailbox controllers using Driver Model"
depends on DM && OF_CONTROL
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

config SANDBOX_MBOX
bool "Enable the sandbox mailbox test driver"
depends on DM_MAILBOX && SANDBOX
help
Enable support for a test mailbox implementation, which simply echos
back a modified version of any message that is sent.
mailbox: add Tegra186 HSP driver Tegra186's HSP module implements doorbells, mailboxes, semaphores, and shared interrupts. This patch provides a driver for HSP, and hooks it into the mailbox API. Currently, only doorbells are supported. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

config TEGRA_HSP
bool "Enable Tegra HSP controller support"
depends on DM_MAILBOX && TEGRA
help
This enables support for the NVIDIA Tegra HSP Hw module, which
implements doorbells, mailboxes, semaphores, and shared interrupts.
mailbox: Introduce K3 Secure Proxy Driver Secure Proxy module manages hardware threads that are meant for communication between the processor entities. Adding support for this driver.

config K3_SEC_PROXY
bool "Texas Instruments K3 Secure Proxy Driver"
depends on DM_MAILBOX && ARCH_K3
help
An implementation of Secure proxy slave driver for K3 SoCs from
Texas Instruments. Secure proxy is a communication entity mainly
used for communication between multiple processors with the SoC.
Select this driver if your platform has support for this hardware
block.
