Apple SoCs have various co-processors required for certain
peripherals to work (NVMe, display controller, etc.). This
driver adds support for the mailbox controller used to
communicate with those.
Say Y here if you have an Apple SoC.

help
Apple SoCs such as the M1 come with various co-processors running
their proprietary RTKit operating system. This option enables support
for the protocol library used to communicate with those. It is used
by various client drivers.
Say 'y' here if you have an Apple SoC.

help
Apple SART is a simple DMA address filter used on Apple SoCs such
as the M1. It is usually required for the NVMe coprocessor which does
not use a proper IOMMU.
Say 'y' here if you have an Apple SoC.
