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

  14         bool "Enable the sandbox mailbox test driver"
  15         depends on DM_MAILBOX && SANDBOX
  16         help
  17           Enable support for a test mailbox implementation, which simply echos
  18           back a modified version of any message that is sent.

  21         bool "Enable Tegra HSP controller support"
  22         depends on DM_MAILBOX && TEGRA
  23         help
  24           This enables support for the NVIDIA Tegra HSP Hw module, which
  25           implements doorbells, mailboxes, semaphores, and shared interrupts.
